HPHT Collection
HPHT Diamond Rings
Formed under extreme pressure and temperature — conditions that mirror those deep within Earth's mantle — HPHT diamonds possess a character and depth that sets them apart. These are diamonds born of elemental force.
Nature's Method
HPHT replicates how diamonds form naturally — under immense pressure (5-6 GPa) and extreme temperatures (1,300-1,600°C).
Unique Character
The intense formation conditions give HPHT diamonds a distinct internal character — a subtle warmth and solidity prized by connoisseurs.
Proven Process
HPHT was the original method for growing lab diamonds, refined over decades to produce crystals of exceptional quality.
