Does a Famous Jewellery Brand Make a Better Diamond?

 The luxury of the name, the value of the stone, and what happens when you come to sell

The luxury of the name, the value of the stone, and what happens when you come to sell

Walking into a prestigious jewellery boutique is an experience.

The polished stone, the carefully designed interior, the champagne, the personal attention and the beautifully presented jewellery all contribute to a sense that you are purchasing something truly exceptional.

And sometimes you are.

But there is an important question that every sophisticated jewellery buyer should ask:

Are you paying for a better diamond or gemstone — or are you paying for the brand surrounding it?

The answer can be both.

The diamond does not know whose box it is in

A diamond’s physical properties do not change because it is mounted in a famous piece of jewellery.

Its colour, clarity, carat weight, cut, proportions, fluorescence and other gemmological characteristics remain the same whether the stone is set by a world-famous luxury maison or an independent jeweller.

A 1.50-carat diamond does not become a 1.60-carat diamond because it carries a prestigious name.

Likewise, a diamond graded as a particular colour and clarity does not automatically become a higher-quality stone because it was purchased from an internationally recognised brand.

This is where independent diamond knowledge becomes important.

DCLA’s Diamond Grading Report provides an independent description of a diamond’s characteristics, including its carat weight, colour, clarity and cut.

A luxury brand can provide extraordinary design, craftsmanship, provenance, service and heritage. But these are different attributes from the intrinsic gemmological characteristics of the diamond itself.

So why can branded jewellery cost so much more?

Because the jewellery is more than its raw materials.

When you purchase from a major luxury house, you may be buying:

  • The brand’s heritage and reputation
  • Original design
  • Highly skilled craftsmanship
  • Boutique and after-sales service
  • Marketing and global recognition
  • Packaging and presentation
  • Limited collections
  • Celebrity association
  • Provenance and collectability
  • The emotional experience of owning it

These elements can have real commercial value.

The important distinction is that commercial value and intrinsic gemmological value are not necessarily the same thing.

Does a famous brand make jewellery more valuable?

Not necessarily.

It can make a piece more desirable to a particular market, and in some circumstances that desirability can translate into a stronger resale price.

But that is not guaranteed.

The secondary market operates very differently from the luxury boutique.

When a customer buys a new piece of jewellery at retail, the price can include the brand, boutique experience, design, manufacturing, marketing, distribution and retail margins.

When the same piece is sold later, the next buyer may not place the same value on those elements.

This is why the original retail price should never automatically be treated as an indication of future resale value.

DCLA has also highlighted the distinction between the price originally paid for jewellery and its potential value when sold later. Retail prices can include manufacturing, design, branding, retail margins, GST and other costs that may not be recoverable in the secondary market.

The difference between retail value and resale value

This is one of the most misunderstood areas of jewellery ownership.

Imagine two rings containing diamonds with broadly comparable gemmological characteristics.

One is purchased from a famous international maison for $50,000.

The other is purchased from an independent jeweller for $25,000.

It would be incorrect to assume that the first ring will necessarily be worth twice as much when it is sold.

The resale market may place considerable importance on the brand — or it may focus primarily on the diamonds, precious metal, design, condition and current market demand.

The circumstances of the sale also matter.

A private sale, specialist auction, dealer purchase, insurance replacement valuation and immediate sale can all produce very different figures.

There is no single “value” for a piece of jewellery.

Where famous brands can make a difference

There are situations where the brand itself can become an important part of the value.

Certain historically significant pieces, rare collections, discontinued designs and jewellery with exceptional provenance can attract collectors.

At auction, the identity of the maker can be highly relevant.

A piece from a recognised maison with documented provenance, original paperwork and a desirable design may have a very different market than an otherwise similar piece from an unknown manufacturer.

But this is the crucial distinction:

The brand can create collectability. It does not automatically create gemmological quality.

What about the diamond itself?

This is where buyers should look beyond the name on the shopping bag.

When considering a significant diamond purchase, understand exactly what you are buying.

Look at:

Carat weight
The weight of the diamond, not simply the overall size of the jewellery.

Colour
For white diamonds, colour grading can have a significant influence on value.

Clarity
The nature, position and visibility of inclusions matter. DCLA’s Diamond Clarity guide explains how clarity is assessed and why it can influence a diamond’s appearance and value.

Cut and proportions
Two diamonds with identical carat weight, colour and clarity can look dramatically different because of their cut and proportions. DCLA explains the importance of diamond cut, proportions, symmetry and polish in determining light performance and appearance.

Natural or laboratory-grown
This distinction is fundamental and should be clearly established. DCLA discusses the differences between natural and laboratory-grown diamonds, including their different market characteristics.

Laboratory report
For significant diamonds, independent documentation can provide important information about the stone’s characteristics.

Provenance
For some exceptional diamonds, documented history can itself become an important part of the story and potentially the market appeal.

The boutique experience is real — and there is nothing wrong with paying for it

There is another side to this discussion.

Why do people buy luxury jewellery from famous boutiques?

Because jewellery is emotional.

People are not always trying to buy the cheapest diamond or achieve the lowest possible price per carat.

They may want to celebrate an anniversary.

They may want a particular design.

They may admire a maison’s history.

They may want the experience of walking into a beautiful boutique and being treated exceptionally well.

They may simply love the piece.

That experience has value to the person buying it.

There is nothing wrong with paying a premium for something you genuinely appreciate.

The mistake is assuming that the premium automatically represents an equivalent increase in the underlying value of the diamonds or gemstones.

Jewellery is not always an investment

This is perhaps the most important point.

A beautiful piece of jewellery can be a wonderful store of wealth, a family heirloom or an object that carries enormous emotional significance.

But buying jewellery primarily because you believe the retail price will automatically be recovered — or exceeded — when you eventually sell is a very different proposition.

Luxury jewellery should not be confused with a guaranteed investment.

Even exceptional jewellery can take time to sell, and the price achieved will depend upon market conditions, the buyer, the selling channel, the condition of the piece, documentation, desirability and many other factors.

So what are you really buying?

When purchasing high-end jewellery, it is useful to separate the purchase into three components:

1. The materials

The diamond, coloured gemstones and precious metals.

2. The craftsmanship and design

The skill involved in creating the piece and the originality or desirability of its design.

3. The brand and experience

The name, heritage, boutique experience, packaging, service, marketing and emotional connection.

All three can have value.

But they are not interchangeable.

A buyer who understands this can make a much more informed decision.

The DCLA perspective

At DCLA, our role is to examine the diamond and provide objective gemmological information about its characteristics.

A diamond does not become scientifically superior because it is sold from a particular boutique.

Equally, a famous brand should not automatically be dismissed as simply a premium for a name. Design, craftsmanship, provenance, rarity and collectability can all contribute to the market appeal of a piece.

The intelligent approach is to understand what portion of the price relates to the diamond, what relates to the jewellery itself, and what relates to the brand.

Then you can decide how much the complete experience is worth to you.

DCLA explains that a diamond grading report is not a valuation. A grading report documents the characteristics of the diamond, while a valuation estimates monetary value for a particular purpose and point in time.

Because ultimately, there is nothing wrong with buying the beautiful box, the boutique experience and the famous name.

Just make sure you also know exactly what is inside the box.

DCLA — Independent Diamond Expertise

When purchasing a significant diamond, independent gemmological assessment can help separate the diamond’s documented characteristics from the marketing and retail presentation surrounding it.

DCLA examines diamonds according to recognised gemmological standards and provides independent diamond reporting and certification services. Its grading process examines characteristics including colour, fluorescence, clarity, cut, proportions, polish, symmetry and transparency.

Know the diamond. Understand the jewellery. Then decide what the name is worth to you.

DCLA reports are gemmological documents and are not valuations. Market value can vary according to the circumstances of sale, market conditions, provenance, design, brand, condition and other factors.

The Extraordinary Rarity of Pink Diamonds: Christie’s Sets a $12 Million Estimate

 8.41-carat pear modified brilliant-cut Fancy Vivid Purple-Pink diamond

Few gemstones command the combination of fascination, rarity and value associated with a natural pink diamond.

Unlike many coloured gemstones, the extraordinary pink colour of a natural diamond is not simply the result of a trace element creating a familiar colour. The science behind natural pink diamonds is considerably more complex. Their colour is generally associated with structural distortion within the diamond’s crystal lattice, created deep within the Earth over immense periods of geological time.

It is this extraordinary combination of natural rarity, geological history and optical beauty that has placed the finest pink diamonds among the world’s most coveted gemstones.

Now, Christie’s is preparing to offer another remarkable example.

At its Hong Kong Magnificent Jewels Autumn Auction on November 24, Christie’s will present an 8.41-carat pear modified brilliant-cut Fancy Vivid Purple-Pink diamond, with an estimate reaching HKD 95 million, approximately US$12 million.

The stone is also classified as Type IIa, adding another notable dimension to its gemmological profile.

When colour becomes the rarity

In the world of diamonds, carat weight is only one part of the story.

For exceptional coloured diamonds, hue, tone, saturation and distribution of colour can be every bit as important as size. A diamond may be large, yet its colour characteristics can determine whether it becomes merely unusual or genuinely extraordinary.

The Christie’s diamond combines several characteristics rarely encountered together: significant size, a strong purple-pink colour, Fancy Vivid intensity and Type IIa classification.

The result is a gemstone occupying an exceptionally rare position within the natural diamond market.

The distinction between a pink diamond and an exceptional pink diamond can be subtle to the untrained eye. Under professional examination, however, the precise characteristics of colour become a sophisticated subject of gemmological analysis.

The science behind natural pink

The colour of most natural diamonds is associated with impurities within the crystal structure. Nitrogen, for example, plays a major role in many yellow diamonds.

Pink diamonds are different.

Their colour is generally linked to deformation of the diamond’s atomic lattice, rather than simply the presence of a colouring impurity. Scientists believe that immense geological forces can distort the crystal structure during the diamond’s formation and subsequent journey toward the Earth’s surface.

This distortion affects the way light interacts with the diamond, producing the extraordinary pink appearance for which these stones are renowned.

The exact relationship between crystal deformation and the resulting colour remains an area of sophisticated scientific study, making pink diamonds particularly fascinating from both a gemmological and geological perspective.

Type IIa: exceptional chemical purity

The Christie’s diamond is classified as Type IIa, a designation that describes the diamond’s chemical composition.

Type IIa diamonds contain extremely low levels of detectable nitrogen and are regarded as among the chemically purest diamonds.

This classification should not, however, be confused with a quality grade.

Type IIa is a scientific classification, not a statement that a diamond is automatically more valuable. A diamond’s desirability and market value depend on the complete combination of its characteristics.

In this case, Type IIa adds another intriguing scientific feature to an already exceptional natural coloured diamond.

Why the strongest pinks are so difficult to find

The rarity of exceptional natural pink diamonds has been reinforced by the limited availability of significant sources of these stones.

For decades, Australia’s Argyle mine in Western Australia was internationally recognised as the world’s most important source of natural pink diamonds. The mine produced an extraordinary range of pink, red and purplish diamonds, but ceased production in 2020.

Its closure fundamentally changed the landscape for the supply of important natural pink diamonds.

While pink diamonds can occur in other deposits around the world, stones possessing the combination of strong colour, exceptional saturation, significant size and desirable clarity remain exceptionally uncommon.

This scarcity has helped establish the finest natural pink diamonds as important collector gemstones rather than simply luxury jewellery.

The auction market for exceptional colour

Major jewellery auctions provide a fascinating window into the upper end of the natural coloured diamond market.

When a rare stone comes to auction, collectors are not simply buying carat weight. They are competing for a combination of characteristics that may never be replicated.

The provenance of a jewel, its laboratory documentation, its natural colour, treatment status, cutting quality and historical significance can all contribute to its desirability.

For a gemstone of this calibre, laboratory examination is therefore fundamental.

A second extraordinary jewel

Christie’s Hong Kong sale will feature another remarkable gemstone in the form of a 10.10-carat Burmese ruby, set within a Cartier brooch incorporating triangular and square diamonds.

The jewel carries a high estimate of approximately HKD 60 million, or US$7.7 million.

The ruby is particularly significant for its Burmese origin and substantial size, while the Cartier design connects the jewel with the maison’s pioneering use of platinum during the early 20th century.

Exceptional Burmese rubies are among the world’s most celebrated coloured gemstones, particularly when they display desirable colour, transparency and other characteristics associated with fine-quality material.

The importance of knowing what lies beneath the beauty

At the highest levels of the jewellery market, beauty and science increasingly go hand in hand.

A spectacular diamond may capture the eye, but professional gemmology seeks to establish what the stone actually is, how its characteristics were formed and whether those characteristics are natural or treatment-related.

For coloured diamonds, this distinction can be particularly important.

Independent laboratory examination can investigate characteristics such as natural versus laboratory-grown origin, colour treatment, diamond type and other identifying features. For important stones, such documentation provides an objective scientific foundation for the jewel’s description.

At DCLA, the Diamond Certification Laboratory of Australia, gemmological examination is centred on independent scientific assessment and reporting in accordance with recognised international standards.

A jewel measured in rarity, not simply carats

The Christie’s 8.41-carat Fancy Vivid Purple-Pink diamond illustrates why exceptional gemstones occupy a category of their own.

Its significance lies not simply in its weight.

It is the combination of natural colour, vivid intensity, purple-pink hue, substantial size, Type IIa classification and exceptional geological rarity that makes the stone so compelling.

As it takes its place under the hammer in Hong Kong, collectors will once again be reminded of one of the enduring truths of the diamond world:

The rarest diamonds are not necessarily the largest. They are the diamonds in which nature has created something extraordinarily difficult to reproduce.

And in the case of a truly exceptional natural pink diamond, that rarity began billions of years before it ever became a jewel.

Diamond Detection Keeps Advancing, And DCLA Has used the Technology for Decades

 DCLA has been at the forefront of diamond detection and disclosure for more than two decades,

The technology used to identify laboratory-grown diamonds continues to advance, with De Beers Group announcing its next-generation SynthDetect™ 2 desktop diamond screening instrument.

For DCLA, however, the challenge of distinguishing natural diamonds from laboratory-grown diamonds is not new.

DCLA has been at the forefront of diamond detection and disclosure for more than two decades, recognising well before laboratory-grown diamonds became a mainstream commercial product that advances in diamond-growing technology would create a major challenge for the jewellery industry.

The next generation of diamond screening

De Beers says its new SynthDetect™ 2 builds on its earlier SynthDetect and SynthDetect XL instruments, introduced in 2017 and 2018.

According to De Beers, the new system is designed to make screening faster, more automated and easier to integrate into the day-to-day operations of diamond manufacturers, laboratories and retailers.

One of the most significant changes is speed. De Beers says a full tray scan that previously took approximately 30 minutes can now be completed in less than five minutes.

The instrument is designed to screen loose diamonds as well as a wide range of jewellery, including rings, earrings, necklaces, pendants, bracelets and bangles. De Beers states that SynthDetect 2 can screen diamonds from 0.001 to 10 carats in the D–J colour range.

The company says automated results, reporting and software updates are intended to further reduce operator input and improve screening efficiency.

De Beers currently lists SynthDetect 2 as being available from Q1 2027.

De Beers SynthDetect™ 2

DCLA recognised the challenge long before it became mainstream

While new screening technology continues to improve, the underlying problem has been known for many years.

DCLA identified the potential impact of synthetic diamond technology on the Australian diamond industry as early as 2002, when the laboratory warned about advances in technologies such as CVD and HPHT and their potential to produce gem-quality laboratory-grown diamonds that could not be reliably distinguished from natural diamonds by ordinary visual examination.

That early recognition is particularly relevant today.

Laboratory-grown diamonds are real diamonds. They have essentially the same chemical composition and crystal structure as natural diamonds and can look virtually identical to the unaided eye.

The distinction is therefore not something that can reliably be established simply by looking at a stone.

DCLA has previously explained that sophisticated gemmological equipment is required to identify the characteristics associated with different diamond growth processes.

DCLA: Lab-Grown Diamonds — A Structural Disruption to the Traditional Diamond Industry

DCLA: What Is a Lab-Grown Diamond?

Detection has always been part of DCLA’s laboratory process

DCLA’s approach has never been based simply on whether a stone “tests as a diamond”.

That distinction is important.

A basic diamond tester can establish that a stone behaves like diamond. It does not necessarily establish whether that diamond was formed naturally or grown in a laboratory.

DCLA’s laboratory uses advanced analytical technology, combined with experienced gemmological examination, to investigate diamond origin, treatments and other characteristics.

DCLA’s published laboratory process states that diamonds are screened for known treatments and tested to establish whether they are natural or man-made, with grading conducted according to International Diamond Council standards.

The laboratory also uses technologies including DiamondView™ fluorescence imaging, which can reveal growth structures and fluorescence patterns that are not visible under normal lighting.

DCLA Technology & Grading Process

DCLA Our Laboratory and Advanced Diamond Testing Technology

Why the technology race matters

The development of instruments such as SynthDetect 2 demonstrates how quickly diamond-screening technology is evolving alongside diamond-growing technology.

As laboratory-grown diamond production has become more sophisticated, identification technology has had to become more sophisticated as well.

This is not simply a question of identifying whether a stone is “real”.

A laboratory-grown diamond is diamond. The critical question is whether its origin has been correctly identified and disclosed.

That distinction becomes particularly important when diamonds are bought, sold, traded, insured, certified or resold.

DCLA has encountered cases where advanced testing has uncovered synthetic diamonds presented in circumstances where their identity or origin was in question.

In one case documented by DCLA, an HPHT-grown synthetic diamond had been fraudulently inscribed with a report number intended to correspond to a natural diamond. Advanced testing identified differences in the stone’s characteristics and growth origin.

DCLA: Synthetic Diamond Fraudulently Inscribed to Match Natural Diamond Report

More recently, DCLA has also highlighted the risk of certificate swapping, where a genuine certificate may be presented with a different diamond from the one originally examined.

DCLA: Consumer Alert — Certificate Swapping Fraud

Screening is not the same as certification

Modern screening instruments are becoming faster and more accessible to the trade, and that is an important development.

However, screening and independent laboratory certification perform different functions.

A screening instrument can help a business rapidly identify stones requiring further examination.

A professional laboratory can go further by independently examining and documenting the characteristics of the individual diamond.

At DCLA, every diamond submitted for certification is examined by accredited gemmologists in the Sydney laboratory, with advanced instrumentation used alongside traditional gemmological examination.

DCLA — Independent Diamond Certification Laboratory

DCLA’s philosophy has remained consistent

The equipment may change.

The technology may become faster.

The screening process may become increasingly automated.

But the fundamental principle remains the same:

Know what the diamond is.

DCLA has consistently advocated transparency, independent testing and accurate disclosure as laboratory-grown diamond technology has evolved.

From recognising the potential impact of synthetic diamonds more than two decades ago, to using advanced detection technology today, DCLA’s role has been to help the Australian jewellery industry and consumers understand what technology can — and cannot — tell them.

As diamond-growing technology continues to advance, diamond detection technology will continue to evolve with it.

For consumers and the trade, that makes independent verification more important than ever.

A diamond may look natural. A basic tester may say “diamond”. But when origin matters, sophisticated testing and independent documentation provide the evidence.

Rare Orangey Pink Diamond to Take Centre Stage at Christie’s Geneva Auction

 14.63 carat fancy orangey pink natural diamond

A remarkable 14.63 carat fancy orangey pink natural diamond is set to be one of the highlights of Christie’s upcoming Geneva jewellery auction, with the David Morris ring carrying an upper estimate of approximately US$2.6 million.

The exceptional stone will be offered as part of Christie’s Exceptional Jewels & Objects of Elegance: A Connoisseur’s Collection, taking place in Geneva on November 10, with an accompanying online auction running from November 5 to 17.

The private collection comprises almost 300 lots and includes important jewellery from internationally recognised maisons including Van Cleef & Arpels, Bulgari and Graff, alongside Art Deco vanity cases and finely crafted gold objects.

Why are natural pink diamonds pink?

Pink diamonds are among the most intriguing of all natural diamonds because, unlike many other coloured diamonds, their colour is not easily explained by the presence of a specific trace element.

The colour of a natural pink diamond is generally associated with changes in the diamond’s crystal structure that occurred deep within the Earth during its formation. Diamonds are made from carbon atoms arranged in an exceptionally precise crystal lattice. In some diamonds, geological forces cause distortions within that lattice.

These microscopic structural distortions affect the way light passes through the diamond, producing the remarkable pink colour that makes these stones so desirable.

When the colour moves towards orangey pink, the diamond displays a combination of pink and orange body colour. The precise appearance can vary considerably from one diamond to another, ranging from delicate pastel tones to highly saturated and vivid colours.

This is one reason every exceptional natural coloured diamond is effectively unique.

For more information about diamond structure, properties and the differences between natural and laboratory-grown diamonds, see DCLA’s guide to What Is a Diamond? Natural vs Laboratory-Grown – Structure, Science and Pricing.

Why are pink diamonds so rare?

Natural diamonds occur in many parts of the world, but diamonds with a strong and attractive natural pink colour are extraordinarily uncommon.

Diamonds are formed under immense pressure and temperature deep within the Earth’s mantle and can take billions of years to reach the surface through geological processes. Only a very small proportion develop the particular crystal characteristics responsible for a natural pink colour.

Importantly, pink diamonds are not confined to one location. Natural pink diamonds have been discovered in diamond-producing regions around the world. However, the supply of fine-quality pink diamonds is exceptionally limited.

The rarity becomes even greater when factors such as carat weight, colour intensity, clarity, cut and overall beauty are taken into account.

A large pink diamond with strong colour and good clarity is therefore extraordinarily difficult to find.

DCLA has explored the extraordinary rarity of large natural diamonds in its article Nature vs Technology: Why Large Natural Diamonds Are Exceptionally Rare, explaining why increasing diamond size results in dramatically greater natural scarcity.

Size changes everything

With coloured diamonds, rarity increases dramatically as size increases.

A small natural pink diamond may already be a scarce gemstone, but a large stone with an attractive, saturated colour can be in an entirely different category.

The 14.63 carat diamond being offered in Geneva is therefore significant not simply because it is pink, but because of its combination of natural colour, substantial size and orangey pink appearance.

At more than 14 carats, the stone belongs to a category where the number of comparable natural diamonds available to the market is extremely small.

This scarcity is one of the fundamental reasons exceptional pink diamonds can command prices far beyond those of similarly sized colourless diamonds.

Natural colour is the key

The distinction between a natural coloured diamond and a treated or laboratory-grown diamond is particularly important when discussing rare pink diamonds.

A natural pink diamond has acquired its colour through the geological processes that formed the stone over an immense period of time. The colour is part of the diamond’s natural characteristics.

Modern technology can produce laboratory-grown diamonds and can also alter the colour of diamonds through various treatments. These stones can be beautiful in their own right, but they are fundamentally different from a rare natural coloured diamond.

For an important natural coloured diamond, independent examination and documentation are therefore critical.

DCLA explains the importance of determining diamond origin in its article Natural or Laboratory-Grown? How Can You Tell What Diamond Is in Your Ring?, which explains why visual examination or a basic diamond tester cannot reliably establish whether a diamond is natural or laboratory-grown.

The challenge of grading coloured diamonds

Coloured diamonds are assessed differently from traditional colourless diamonds.

The colour itself is a major component of the stone’s rarity and desirability, with factors including hue, tone and saturation playing an important role.

Two diamonds of exactly the same carat weight can therefore have dramatically different values because their colours differ in strength, distribution and attractiveness.

For a buyer or collector, establishing whether the colour is natural, determining the characteristics of the diamond and confirming any treatments is essential.

At the Diamond Certification Laboratory of Australia (DCLA), diamonds undergo detailed examination using advanced laboratory technology. DCLA states that every diamond is screened for known treatments, tested to establish whether it is natural or man-made, and graded according to International Diamond Council (IDC) rules.

Learn more about the DCLA Diamond Grading and Certification Process.

Why independent certification matters

With an exceptionally rare coloured diamond, establishing exactly what the stone is becomes particularly important.

A DCLA diamond grading report provides a technical breakdown including carat weight, colour, clarity, measurements, stone type, treatments or enhancements, cut, symmetry, polish, transparency and fluorescence.

For rare natural coloured diamonds, documentation can therefore become an important part of the stone’s history and provenance.

DCLA’s Diamond Grading Report service provides independent documentation of the diamond’s characteristics.

Why exceptional pink diamonds command exceptional prices

The market for the finest natural pink diamonds is ultimately driven by a simple combination:

Nature created very few of them, and the world’s supply cannot simply be increased.

A large, naturally coloured pink diamond with attractive colour, good clarity and excellent cutting represents the convergence of several rare characteristics.

This scarcity is particularly important in today’s diamond market. While laboratory-grown diamonds can be produced using controlled manufacturing processes, the supply of large, exceptional natural diamonds remains limited by geology.

DCLA’s research into the changing natural diamond market notes that large, rare and unusually coloured natural diamonds continue to command strong premiums because of their exceptional rarity and provenance.

The Christie’s Geneva offering demonstrates the continuing fascination with these extraordinary natural treasures. While the US$2.6 million upper estimate is substantial, the importance of the stone extends beyond its auction price.

It is a reminder that in the world of natural diamonds, rarity is not simply about size. It is about how many times nature was able to create the right combination of colour, structure, clarity, size and beauty.

And when that combination occurs naturally, there may be very few comparable diamonds anywhere in the world.
