Why Lab-Grown Diamonds?
Lab-grown diamonds are created using CVD or HPHT technology under controlled conditions, producing stones with the same crystal structure, hardness (10 on the Mohs scale), and optical properties as earth-mined diamonds. They are graded identically using the 4Cs — cut, color, clarity, and carat — and certified by the same independent laboratories. Lab-grown diamonds typically cost 60–80% less than comparable mined diamonds.
