What are Lab‑Grown Diamonds?

Lab‑grown (or synthetic) diamonds are chemically, physically, and optically identical to naturally mined diamonds—they differ only in their origin. Created in a controlled laboratory, these gems offer the same sparkle without mining impacts.

How Are They Created?

There are two main methods:

• High‑Pressure High‑Temperature (HPHT): Mimics natural formation deep in the Earth.
• Chemical Vapor Deposition (CVD): Builds diamond layers atom-by-atom in clean chambers.
  Both techniques yield genuine diamonds with identical properties to mined ones.
