They have the same chemical composition, brilliance, and hardness (10 on the Mohs scale) as natural diamonds.
For modern buyers looking for value, sustainability, and style, lab-grown diamonds have quickly become the preferred choice.

Producing lab-grown diamonds generally requires less environmental disruption.
Greater Value
Buyers can often purchase larger carat diamonds for the same budget.
Same Brilliance
Lab-grown diamonds are physically and chemically identical to natural diamonds.
