Lab-grown diamonds" attracting attention

In recent years, "lab-grown diamonds (synthetic diamonds)" have attracted attention due to their environmental friendliness and affordability.
It has attracted the interest of many people as a sustainable alternative with properties comparable to those of natural diamonds.
However, in 2025, there was major news for the industry at the "JCK Show," the world's largest jewelry exhibition held in Las Vegas.
Al Cook, CEO of De Beers, announced that the company would discontinue the production of lab-grown diamonds under its "LIGHTBOX" brand.
He commented that he believes the value of lab-grown diamonds lies not in the jewelry sector, but in the technology sector, creating a stir in the industry.
Indeed, lab-growns are made with the same composition as diamonds.
When I think about it, it seems to be the result of the technology of our predecessors.
What De Beers' Withdrawal Means
This announcement is also said to symbolize that the lab-grown diamond market has reached a turning point from its rapid growth period.
Although Labgrown has received some temporary attention due to lower prices and an expanding market,
In recent years, there has been a growing movement to reevaluate the "enduring value" and "rarity" of natural diamonds.
Of course, both natural and artificial diamonds have their own advantages and disadvantages, and neither is superior to the other.
What is important is what value is important to you, and what thoughts and feelings you put into your selection.
