How the Largest Jewelry Companies in the World are Marketing Lab-Grown Diamonds

25 october 2021

This article written by Paul Zimnisky was carried by the Solitaire International Magazine and now it is published on Rough&Polished by permission of the author and the magazine.

During a four-hour-long analyst event in September, the largest fashion-jeweler in the world, Pandora, provided an update on its recent foray into lab-grown diamonds. The line, branded as “Pandora Brilliance” is currently being tested exclusively in the company’s UK market, however, management said that a global rollout decision “will probably come towards the end of the year” as the company is still “learning how to maneuver in the space.”

Pandora, which is known for its iconic charm bracelets, sells an estimated 100 million pieces of jewelry a year –with the average customer purchase estimated at around US$75 for two items. Pandora Brilliance adds a new dynamic to the company’s merchandise mix with an initial price point that ranges from £250 (US$340) for a 0.15-carat lab-diamond set in silver to £1,290 (US$1,765) for a 1.0-carat stone set in gold.

With 6,700 point of sale in more than 100 countries, Pandora is likely the largest jewelry company in the world to enter the lab-diamond space –as CEO Alexander Lacik articulated in a Bloomberg interview in June: “there have been a lot of small players putting their fingers into the (lab-diamond) pot, but no one with muscle…we (will be) applying the marketing muscle.”

However, Lacik has also stressed that the company’s lab-diamond strategy is a means to “democratize” diamonds, making them “affordable” to a larger population. The Pandora Brilliance line includes pendants, earrings, bracelets and rings –although the rings are not directly being marketed as engagement rings. Accordingly, it appears that Pandora’s marketing approach to lab-diamonds is more “fashion-jewelry” oriented –positioning the product to primarily cater to a new consumer base rather than the existing diamond-buying demographic.

Swarovski, another iconic global fashion jewelry-brand, debuted a collection of fancy-colored lab-diamonds in early-2020 after having tested various lab-diamond strategies in the preceding years. The line, which is available in 16 vibrant proprietary colors including “Androgyny Flamingo,” “Cubist Sky” and “Heavy Metal Cherry,” does not appear to be positioned as a bridal product either.

That said, mid-market U.S. department store majors, Macy’s and JCPenney, began selling lab-diamonds in 2018 which includes engagement ring offerings. Neither company has provided public feedback on the success of the product so far.

Signet Jewelers, the largest jeweler in the U.S., and parent of Kay Jewelers, Zales and James Allen, began selling a limited amount of lab-diamonds with bridal options in 2019. However, Signet is seemingly yet to aggressively market the product or provide public feedback on the appetite of the offering. For example, as of October 2021, the Zales’ website still prominently displays natural diamonds on the landing page, with no mention of lab-diamonds.


Notably, all of the above companies currently selling lab-diamonds have historically sold other man-made gems or diamond simulants, e.g. lab-created ruby, emerald, sapphire, moissanite or crystal. On the other hand, notable fine and high-jewelers that historically have not carried lab-created stones (of any sort) do not currently sell lab-diamonds.

Tiffany & Co., the largest jeweler in the world, as well as iconic high-jewelers such as Cartier and Bulgari, do not include lab-diamonds in their merchandise assortment. Nor does Chow Tai Fook, Luk Fook or Chow Sang Sang, the largest jewelers in Greater China. In a direct correspondence with Luk Fook earlier this year, an executive said they do not sell lab-diamonds as they see it for “another kind of customer.”

Privately-held Blue Nile, which is speculated to be the largest online retailer of diamonds globally, began offering De Beers’ Lightbox lab-diamonds late last year. The line is exclusively sold as non-bridal jewelry and is priced at a liner US$800-per-carat (up to 2-carat solitaire in size). On a JCK Jewelry District Podcast in September, the CEO of Blue Nile Sean Kell noted that the company’s average engagement ring selling price is about US$10,000, noting that the company identifies as a “fine-jeweler.”

Blue Nile competitor, Brilliant Earth, which went public in the U.S. in recent weeks at a valuation exceeding US$1 billion, is speculated to be the largest seller of lab-diamonds globally. While the company has been selling lab-diamonds since 2012 it has yet to provide any quantitative sales metrics on the category –however, the company’s average sale is over US$3,100, which includes natural diamonds.
