DeBeers Exits the Synthetic Jewelry Biz

Lightbox to Close

Here's the Reason Why Now!

Gary Roskin

Roskin Gem News Report

In our “Spotlight on De Beers – the Las Vegas Presentation” from last year’s JCK Show (June 2024), Al Cook, Chief Executive Officer of the De Beers Group, told us that De Beers would no longer be in the synthetic diamond jewelry business!

He told us then, “We believe that the value of Lab Grown Diamonds lies in technology rather than in jewelry. So, De Beers will suspend production of lab grown diamonds for jewelry, and instead, we will evolve Element Six so it’s not just a leader in producing synthetic diamonds, but it becomes THE leader in synthetic diamond technology solutions. This starts with concentrating all our resources in a single world class CVD hub here in the United States, in Portland, Oregon.”

Recap – De Beers brought down the price of LGDs by entering the synthetic diamond jewelry market (Lightbox), and now that prices have fallen even farther below where De Beers thought they might end up, they no longer need to be in the business.

At that time, in June 2024, Lightbox still had plenty of inventory, so they were not going away just yet. But we knew that as soon as they reduced their inventory, they would be gone.

And now here we are, almost one year later, announcing the closure of Lightbox.

With so many of our readers in the gem trade, we thought it was worth including these JSA trade show security tips for both exhibitors and buyers.

They may not be gem-specific, but they’re about something just as important—keeping you safe, along with the gems and jewelry you’ve worked so hard to bring to – and take home from – the show. – gr

A Message from Jewelers Security Alliance

Trade shows are valuable opportunities to reconnect with friends, industry colleagues, and meet future customers. However, proper security practices must be a top priority for everyone involved.

Show management, show security, and law enforcement work hard to keep the shows—and the city—safe. But the responsibility also lies with exhibitors and attendees to follow sound security protocols.

If you are heading to a trade show, whether exhibiting or buying, these important security measures should already be checked off your list.

If not, get busy!

The endless seas are the great creative frontier in jewellery today, inspiring numerous high jewellery collections unveiled and presented this year

The sea is this year’s leading inspiration for jewellers

Something’s in the air lately in jewellery design—or in the water, rather. For millennia, we’ve looked above and below to wonder about our place in the world. Yet for all the discoveries, very little continues to elude, fascinate and inspire like the ocean. The vast seas—they cover significantly more area on our planet than land, mind you—have shaped and defined cultures, trade and history. The siren song of the seas is as hypnotic as it is varied, as we are seeing being played out in several recent collections of jewellery inspired by the sea.



Robert Louis Stevenson’s adventure novel Treasure Island was the inspiration and namesake behind Van Cleef & Arpels’s newest range of high jewellery. It’s perhaps the maison’s most playful collection in years, with nods to a pirate adventure and a search for hidden treasure. It gleefully takes on board these childlike symbols and motifs, and turns it on its head with the maison’s signature grace and elegance.

Check out this latest trend in Singapore Vogue!

Selections based on a soft track.

Race 1

1. Gemologist had a number of trials before making his debut in a small field at Muswellbrook and coming with a strong finishing burst to score a strong win.

He’s drawn the rails in this and should get the run of the race and take plenty of beating again. 

3. Forging Ahead is on debut for Kris Lees and has had two trials in preparation. He looks set to run well. 

9. Josephine has had two trials to be readied for this debut, and she has looked good in each of them. 

2. Cornerback is a stablemate of Forging Ahead and also having his first start. He shouldn’t be taken lightly after a couple of trials.

How to play it: Gemologist WIN.
