Lightbox Is Now Selling Loose Lab-Grown Diamonds
Meant to capitalize on the customization trend, the stones are priced using the brand’s $800-per-carat structure.

Lightbox Loose Stones are available to purchase on the brand’s website in pink, blue, and white in sizes up to 2 carats. They are priced according to the brand’s uniform $800-per-carat structure.
Lightbox’s initial offering includes round brilliant and princess cuts. The company said additional cuts will be released early next year.
Each loose diamond comes with its own quality guarantee, and every Lightbox lab-grown diamond is inscribed with a mark visible with a 10x loupe.
The move to offer loose diamonds comes as Lightbox sees an increased demand for custom pieces, particularly from women shopping for themselves, the company said.
“From the beginning, we have had inquiries from consumers who see our lab-grown diamonds—with their unbeatable price, great quality and range of color—as an opportunity to explore their creativity, making something that is unique to them,” said Lightbox CEO Steve Coe.
“We are thrilled to launch this exciting new concept that offers a simple and accessible way to create fun and affordable, custom-designed lab-grown diamond fashion jewelry using our colorful array of stones. Lightbox Loose will open up a world of possibilities for a broad range of consumers to experiment with customization, personalization and creative design.”
Coe noted to National Jeweler that the affordable price points give consumers greater freedom to experiment with designs and take a few risks.
“This is probably something you wouldn’t want to do with a $8,000 natural diamond, but it’s a real option for an $800 lab-grown stone. We believe this could be a great additive opportunity for Lightbox.”
The loose stone collection is available on the Lightbox website now, along with a selection of one-of-a-kind pieces created for Lightbox by jewelers who specialize in custom work, with the intention of inspiring shoppers.
Lightbox created an online purchase and referral experience. Consumers can select and buy individual Lightbox lab-grown diamonds, look through the custom designs, and, if needed, select from a vetted list of established jewelers who have expressed a willingness to work with customers to bring their designs to life.
Coe confirmed the brand is open to collaborating with other jewelers and potentially adding more to its list as it adds cuts to the loose stone offerings.
Lightbox will soon make the loose diamonds available through its retail partners as well, starting with Reeds Jewelers, which will have the product in time for the holiday season.
A wider rollout to other brick-and-mortar retailers will follow in the new year.
The launch is the latest in a series of new offerings from the lab-grown diamond brand, including the August introduction of larger stones weighing up to 2 carats and “Finest,” a proprietary diamond engineering process developed by the brand that combines its existing CVD synthesis technology with a “further leading refinement” to enhance the stones’ color.
“Finest” stones are VVS clarity, colorless (D, E, or F in color), and have an excellent cut.
They will also be available in the loose offerings.
