Are lab-grown diamonds real?

Yes. They are crystalline carbon with the same hardness and sparkle as mined diamonds. The certificate states the origin.

Why do they cost less?

Supply. Labs can grow diamonds to order. Natural crystals of the same size and grade are rarer, so the market price is higher.

Lab-grown diamonds
