What Are Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds, "grown" in laboratories using advanced technology. They are identical to natural diamonds formed deep underground billions of years ago in chemical composition, crystal structure, physical hardness, and optical performance—pure carbon, equally brilliant.

They are not imitations, nor are they fake diamonds. If natural diamonds are compared to icebergs in nature, then lab-grown diamonds are the ice crystals formed in your cup—identical in composition, different in origin, equally beautiful.
