Diamond Setting Styles: Beauty, Light Performance and Security – Choosing the Right Setting for Every Gem

 The Purpose of a Jewellery Setting

When most people admire a beautiful diamond ring, they naturally focus on the gemstone itself. Yet one of the most important decisions in jewellery design isn’t the diamond—it’s how the diamond is set.

The setting influences far more than appearance. It determines how much light reaches the gemstone, how secure it will remain during everyday wear, how easily it can be cleaned, and even how large or brilliant it appears.

There is no single “best” setting. The ideal choice depends on the gemstone’s shape, durability, intended use, and the wearer’s lifestyle. Understanding the differences helps ensure both beauty and longevity.

The Purpose of a Jewellery Setting

A jewellery setting has three primary roles:

  • Securely hold the gemstone.
  • Maximise the stone’s visual appeal.
  • Complement the overall design of the jewellery.

Finding the right balance between these objectives is the hallmark of good jewellery design.

Claw (Prong) Settings

The claw setting is the most recognised and widely used method of setting diamonds.

Small metal claws grip the gemstone around its girdle while leaving most of the stone exposed.

Advantages

One of the greatest strengths of a claw setting is light performance.

Because very little metal covers the diamond, light can enter from the top and sides before reflecting back through the crown. This often produces exceptional brilliance, fire and scintillation.

Other advantages include:

  • Maximum light exposure
  • Makes the diamond appear larger
  • Easier to clean
  • Classic and timeless appearance
  • Suitable for almost every diamond shape

Disadvantages

With more of the diamond exposed, the stone is also more vulnerable to knocks.

Over many years of wear, claws can gradually wear down, bend or catch on clothing. If this occurs unnoticed, the security of the diamond may be compromised.

Regular inspections by a qualified jeweller are recommended, particularly for engagement rings worn every day.

Bezel Settings

A bezel setting surrounds the gemstone with a continuous rim of precious metal.

Rather than gripping the stone with claws, the metal wraps around the edge, securely locking it into place.

Advantages

Bezel settings offer exceptional protection.

The surrounding metal shields vulnerable edges and corners from accidental impacts, making them ideal for active lifestyles.

Benefits include:

  • Outstanding security
  • Excellent protection against chips
  • Smooth profile that won’t catch on clothing
  • Modern, elegant appearance
  • Ideal for everyday wear

Light Performance

Because the metal surrounds the edge of the gemstone, slightly less light enters from the sides.

For well-cut diamonds this difference is often minimal, but coloured gemstones may appear deeper or richer in colour due to the enclosed design.

Many designers intentionally use bezels to enhance coloured gemstones such as sapphires, emeralds and rubies.

Pressure (Tension) Settings

One of the most visually striking styles is the pressure, or tension, setting.

Rather than traditional claws, the gemstone is held in place by carefully engineered pressure within the metal band itself, creating the illusion that the diamond is floating.

Advantages

  • Contemporary appearance
  • Maximum visibility of the gemstone
  • Excellent light exposure
  • Unique and minimalist design

Engineering Matters

Although they appear delicate, genuine tension settings are highly engineered.

The ring must be manufactured with extremely precise tolerances so the pressure remains constant throughout the life of the ring.

This is not a setting style suitable for every gemstone.

Only durable stones with sufficient hardness and toughness—such as diamonds and some sapphires—are generally considered appropriate.

How Light Affects Beauty

Many consumers assume that more exposed stone automatically means more sparkle.

While greater light exposure certainly helps, sparkle primarily comes from the quality of the diamond’s cut.

A poorly cut diamond in an open claw setting may still appear lifeless, while an exceptionally cut diamond in a bezel setting can remain brilliantly attractive.

The setting enhances beauty—but it cannot compensate for poor cutting.

Security vs Brilliance

Jewellery design often involves balancing competing priorities.

A six-claw solitaire may maximise brilliance while offering good security.

A bezel may sacrifice a small amount of side light but significantly increase protection.

The best choice depends on how the jewellery will be worn.

For engagement rings worn every day, security often becomes just as important as appearance.

Why Diamond Shape Changes Everything

Not every diamond shape performs equally in every setting.

Round Brilliant

The strongest and most versatile shape.

Works exceptionally well in claw, bezel and tension settings.

Princess Cut

Its pointed corners are vulnerable to chipping.

V-shaped claws or bezel settings provide much greater protection.

Emerald Cut

Large open facets emphasise clarity rather than sparkle.

Bezel settings often complement its elegant geometric appearance while protecting its cropped corners.

Pear, Marquise and Heart Shapes

These shapes all feature delicate points that require additional protection.

Specialised claws or partial bezels are commonly used to reduce the risk of damage.

Oval and Cushion Cuts

These shapes are extremely versatile and perform beautifully in most setting styles.

Coloured Gemstones Require Different Considerations

Unlike diamonds, many coloured gemstones have different hardness and toughness.

Emeralds, for example, are significantly more susceptible to chipping due to their natural internal fractures.

Tourmalines, opals and tanzanites also require greater protection than diamonds.

For these gemstones, bezel settings or protective claw arrangements often provide the safest long-term solution.

Lifestyle Should Guide the Design

A setting should suit the owner’s lifestyle as much as their personal taste.

Someone working with their hands every day may benefit from the security and low profile of a bezel setting.

A person seeking maximum brilliance in an engagement ring may prefer a traditional claw setting.

Athletes, healthcare workers and tradespeople often choose lower-profile settings that reduce the risk of accidental impact.

Craftsmanship Makes the Difference

Regardless of the setting style chosen, craftsmanship remains the most important factor.

Poorly positioned claws, uneven bezels or incorrectly engineered tension settings can all compromise both beauty and security.

An experienced jeweller understands how metal behaves over decades of wear and how different gemstone shapes respond to everyday use.

The best jewellery combines engineering with artistry, ensuring the setting protects the gemstone while allowing it to display its full beauty.

Final Thoughts

A diamond or coloured gemstone may be the centrepiece of a piece of jewellery, but the setting is what allows it to shine safely for generations.

Whether choosing a classic claw setting, a protective bezel or a striking tension design, the decision should always consider light performance, durability, gemstone shape and the wearer’s lifestyle.

Beautiful jewellery is not simply about selecting an exceptional gemstone—it is about designing a setting that allows that gemstone to remain secure, brilliant and admired for a lifetime.


DCLA Note: Professional inspection of gemstone settings is recommended every 12 months, particularly for rings worn daily. Routine maintenance can identify worn claws, loose stones or metal fatigue before a gemstone is lost, helping preserve both the beauty and value of your jewellery.

Your Engagement Ring Probably Has A Hidden Serial Number You Didn't Know About

If you've ever gone through the process of shopping for an engagement ring, you'll know there can be an overwhelming number of things to consider.

Aside from the look and style of your ring, you quickly start to learn an awful lot about diamonds, from the cut, to the colour and clarity.
What you may not know is most diamonds in Australia over the last 10 years have been laser inscribed with a serial number likened to a 'fingerprint' -- which makes it easier to trace should the unfortunate event that your engagement ring is lost or stolen ever take place.
This code in turn makes your ring a 'low risk' theft item because it's easy for police to trace it. But don't go pulling your ring off your finger to check for that little serial number just yet.
The code is inscribed directly onto the girdle of the diamond which is quite difficult to get to when it's in a setting and it can't be seen with the naked eye either, having to be checked under a microscope instead.

Speaking to 10 daily, Roy Cohen, a diamond expert from Certified Diamond Insurance, said this spot was specifically chosen instead of on the engagement ring band as this could be lost if it was melted down. Yet removing the code from the diamond itself is near impossible.
"It cannot be removed unless the diamond goes back to a diamond polishing factory where it is put back on the wheel and polished off. I mean, there are very few diamond polishing factories in Australia so the chances of that happening are very remote," Cohen said.
"It’s even harder than for example, the engine number of a motor car. They could just machine it off. I mean, anyone could do that. But with a diamond? No. Only diamond cuts diamond."

This process of inscription is completed by Certified Diamond Insurance (CDI) who are in partnership with a Australia’s leading diamond certifier, Diamond Certification Laboratory of Australia (DCLA), as well as the Woodina Underwiting Agency.
Together they're working towards driving the costs associated with insuring diamonds down for Australians, with new research finding almost half of Australia diamond engagement rings aren't insured. If they are, 70 percent of these have inadequate insurance as they're usually lumped with other items as part of home contents insurance.
"If you go and get household insurance, you’ll be paying a standard kind of rate and because they cover everything, you’ll be paying slightly higher premiums," Cohen said.
"What we’ve done is we’ve pulled out all certified diamonds that are laser inscribed and we only ensure those diamonds. These are the lowest risk diamonds."
Laser inscribed diamonds are considered 'low risk' diamonds. Image: Supplied
According to Cohen, these diamonds are a 'thief's worst nightmare' because they often aren't able to tell if it has been laser inscribed or not.
"Thieves can get caught so much easier with this type of diamond. If they go and sell that to a hock shop and it has the laser inscription on it, it is very easy to identify that that diamond has been stolen," he told 10 daily.
So how can you check if your diamond has the laser inscription on it or not? According to Cohen, it's as easy as checking your diamond certification certificate.
"Most diamonds that are of value are sold with diamond grading certificates in Australia and most of those are laser inscribed," he said.The certificate will make note that the diamond has been laser inscribed and it will have the number that’s on the actual diamond.
Yet while most diamonds now have the laser inscribed code on them, if your engagement ring happens to be an heirloom or has been passed down through the family, it likely doesn't. The upside is CDI are offering complementary diamond grading and laser inscription for diamonds owners in this situation.
"So if anybody wants take advantage of the lower premiums that CDI is offering and the diamond is not certified and not laser inscribed, we will actually do that for them," he said.
"The diamond gets removed from the setting, the diamond is graded, laser inscribed and then set back in the setting. Then it is eligible for CDI insurance."

CDI are further working on establishing a nation wide data base where individuals can register their ring along with it's details and pictures. Should the ring ever be lost or stolen, it can then be flagged in this system, making it easier to locate.
"Then wherever it ends up or if it’s ever checked against that data base or it ends up at a diamond grading laboratory, it will be identified," Cohen said.
"So the benefit is, let's say it was a heritage diamond from your grandma or something like that, you actually have a chance of getting the diamond back."
