How Man Made Diamonds Are Produced

The two production methods differ in process and equipment.

High Pressure High Temperature (HPHT)

This method mimics natural diamond formation. hpht diamonds Carbon is placed under extreme heat and pressure until it crystallizes into a diamond. HPHT diamonds are often used to improve the color of lower quality diamonds.

Chemical Vapor Deposition (CVD)

CVD uses carbon-rich gas in a vacuum chamber. The gas deposits carbon onto a substrate, slowly forming diamond crystals. CVD allows precise control over the diamond’s shape and clarity. man made diamonds
