Over 90% Price Drop in 6 Years – A Price That Speaks for the Future:
Why Did De Beers Stop Betting on the Future of CVD Lab-Grown Diamonds (LGD)?

In 2018, De Beers launched its Lightbox brand with an attractive retail price:
THB 180,000 per carat for a 1-carat D VS1 CVD Lab-Grown Diamond (LGD).

But by 2025, wholesale prices of LGDs have plunged to just:
THB 5,000 per carat for a 1-carat D VS1.

This represents a staggering 93% price drop in just six years, turning CVD Lab-Grown Diamonds into a low-margin, commoditized product — one that fails to offer a compelling value proposition when compared to natural diamonds.

"Lab growns have become a low-margin, commoditized product."
— IDEX Online

Faced with this reality, De Beers made a critical decision:
To stop producing CVD Lab-Grown Diamonds for jewelry, and refocus entirely on highlighting the rarity and inherent value of natural diamonds.
