Extreme Physics Applied to Carbon

HPHT (High Pressure High Temperature) technology recreates the conditions occurring naturally more than 150 kilometers below the Earth's crust. Using sophisticated cubic presses, pressures of up to 60,000 atmospheres and temperatures exceeding 1,500 °C are applied to a growth cell containing purified carbon and a metal catalyst.

The Birth of the Perfect Crystal

Under these extreme conditions, carbon changes its molecular structure from graphite to diamond, depositing atom by atom onto a crystalline diamond seed. This miracle of modern physics takes 8 to 12 weeks of constant supervision.
