Lab-grown diamonds chemically identical to real diamonds but 70-80% cheaper; natural diamond prices down.

Biologically, they're the exact same thing. The only way you can tell the difference between a lab-grown stone and a real diamond is if you take it to a jeweler who has a very special machine that can tell the difference between a lab-grown diamond and a regular diamond. But, a diamond tester won't do it. But, chemically, they're literally identical. And because of this, natural diamond prices have been going down. They're down 70% in the last 15 years, and more than 50% in the last 4 years as lab-grown stones are cheaper. 70 to 80% cheaper. And uh they have captured up to 45% of US engagement rings, up 5% from 5% 2019.
