How Lab-Grown Diamonds Are Created
Two advanced methods — both produce 100% authentic diamonds
HPHT Method
High Pressure High Temperature mimics natural diamond formation. A diamond seed is subjected to 1.5 million PSI and 2,700°F. Carbon atoms bond to the seed layer by layer — ideal for colorless and fancy-colored diamonds.
CVD Method
Chemical Vapor Deposition uses a carbon-rich gas chamber. Energy causes carbon atoms to crystallize on a diamond seed. Precise control over quality — most commonly used for modern lab-grown jewelry.
Both methods produce diamonds graded with the same 4Cs as natural diamonds. Even professional gemologists cannot distinguish without specialized equipment.
