Frequently Asked Questions

Lab-grown diamonds are genuine diamonds created in controlled laboratory environments using advanced technology that replicates the natural diamond formation process. They possess the same chemical composition (pure carbon), crystal structure, and optical properties as mined diamonds — the only difference is their origin.

Absolutely. Lab-grown diamonds are chemically, physically, and optically identical to natural diamonds. They score a 10 on the Mohs hardness scale and exhibit the same brilliance, fire, and scintillation. The Federal Trade Commission recognizes lab-grown diamonds as real diamonds.

Lab-grown diamonds offer the same beauty and durability as natural diamonds, typically at a more accessible price point. They are graded using the same 4Cs — cut, color, clarity, and carat weight. The key advantage is that lab-grown diamonds are produced with significantly less environmental impact than traditional mining.
