Luminous Diamonds’ Debut Collection Celebrates Your Inner Glow

 


The new fine jewelry company is a leader in rare fluorescent stones.

All diamonds shimmer when light hits them. Under master hands, they are cut into interesting shapes that spark joy. Gems from Luminous Diamonds, a new fine jewelry brand, however, have an attribute that many precious stones don’t: They glow.

Luminous Diamonds’ parent company, Alrosa, is a leader in sourcing fluorescent stones, which are formed under unique geological conditions that leave trace elements during the carbon crystallization process. As a result, Luminous Diamonds shine extra bright in the sun and, most intriguingly, emit a blue glow under UV light.

“These diamonds are stunning, luminous, and make a statement,” says Rebecca Foerster, Alrosa’s president of North America. “They reflect the way modern women wear confidence like a rare jewel, and they dare us all to stand out by sharing our inner selves. Greatness in people, like diamonds, is made under pressure. When a woman follows her own inner light, others see it. Our diamonds are an enduring reminder of this light.”

To highlight this point, Luminous Diamonds enlisted female leaders from disparate industries to model its debut collection in a campaign titled Greatness Under Pressure. They are WNBA athlete Skylar Diggins-Smith, attorney and travel writer Cynthia Andrew, violinist Ezinma Ramsay, gender-fluid advocate Elliott Sailors, model Denise Bidot, and photographer Marian Moneymaker.

The 28-piece collection consists of brilliants and pavé diamonds on open-work hexagon settings. They include long necklaces with pendants, crawler and chandelier earrings, and bracelets. Each design comes with an illuminator charm that emits UV light so you can get that inner glow all the time.

Alrosa steps up efforts to brighten fluorescent diamond sales


Russia’s Alrosa the world’s top diamond miner by volume, is betting on a new strategy to boost its sales amid an industry-wide slowdown that has hit small companies the hardest.
The state-owned company is now selling naturally occurring fluorescent diamonds mixed with others. At the same time, it’s holding talks with global jewellery retailers about jointly marketing its ‘Luminous Diamonds’ brand, which uses the glowing stones.
Fluorescence, a bluish glow produced by ultraviolet rays (UV), is a characteristic of 25% to 35% of diamonds, according to the Gemological Institute of America (GIA).

The feature has traditionally been seen as a negative attribute as it can make a diamond appear “milky” or “oily” in direct sun or UV light. Alrosa’s marketing efforts are centred on changing those perceptions.
Glowing diamonds are most common in Russia and Canada due to their proximity to the Arctic, where they are usually found.
GfK market research agency recently conducted a study involving over 4,000 jewellery consumers to determine how they perceived fluorescent diamonds.
The survey revealed that 74% of the respondents in the US didn’t know what they were or were poorly informed about them. When educated, however, over 82% of respondents said they would consider buying a diamond with such a feature. And almost 60% of customers, mostly millennials, expressed their willingness to pay as much as 15% more to obtain a fluorescent diamond.
About half of all diamonds produced globally have some fluorescence, but those in which the feature is “strong”  —  the focus of Alrosa’s campaign —  represent as much as 5-10% of global supply.
Global demand for all types of diamonds fell between 2018 and 2019, affecting small stones producers the most, due to an oversupply in that segment that dragged prices down.
Increasing demand for synthetic diamonds also weighed on prices. Man-made stones require less investment than mined ones and can offer more attractive margins.
Big companies have not been immune to the downward trend. De Beers, the world’s No. 1 diamond miner, reported in February its worst set of earnings since Anglo American acquired it in 2012.

Fluorescence Has No Negative Impact on Diamond Colour



HRD Antwerp, a leading European authority in diamond certification, recently undertook a study entitled “The Effect of Fluorescence on the Colour of a Diamond”, concluding that even strong fluorescence does not negatively impact a diamond’s appearance. In fact, their findings demonstrate the contrary: under normal conditions and even when outdoors, strong fluorescence has a positive influence on the color of diamonds.

This finding directly contradicts the common perception that fluorescence is a negative property of diamonds, driving down their value. Given HRD Antwerp’s findings, they conclude there is no justification for the price penalties that currently apply to fluorescent diamonds.

Fluorescence, along with the 4Cs (carat weight, clarity, color and cut) is an important characteristic of a diamond and influences its value. Typically, in the diamond trade, it is perceived as a negative property, which drives the value of fluorescent diamonds down. HRD Antwerp’s study found this common perception is not justified. To make this determination, the lab set out to identify how fluorescence influences the color grading results by gemologists in standard laboratory environments, as well as to assess how fluorescence influences the visual appearance of a diamond for regular consumers. The latter was in fact the main purpose of the study: to determine the impact on the appearance of a mounted diamond as observed by an end consumer.

The experiments HRD Antwerp conducted in its laboratory revealed several significant points, foremost of which is that diamond fluorescence has no influence on the color grading of a diamond in a laboratory environment, due to the insignificant UV content in conventional grading lamps. In short, fluorescence should not lower the official color grade. Furthermore, conventional grading through the pavilion (lower half) of a diamond in outdoor conditions actually improves the color grade for diamonds with a fluorescence grade above ‘medium’.

 As an example, a diamond graded in the HRD Antwerp laboratory as a J color with very strong fluorescence can appear as a D color when examined in outdoor conditions. When the diamond is examined through the table (face up), there is still an improvement in color, although this change is less significant.

The results of HRD Antwerp’s study thus support findings from earlier studies conducted by other labs, adding additional objective assessments. It confirms that even very strong fluorescence has no detrimental effect on the appearance of diamonds in a laboratory setting, and when viewed through the pavilion in outdoor conditions, it results in a clear improvement in a diamond’s color. For the wearer or casual observer, fluorescence has a neutral or even positive impact on the appearance of a diamond, making it appear to be more colorless.

Given these observations, HRD Antwerp concludes there are no grounds on which to justify the price penalties that currently apply to fluorescent diamonds.
