HPHT Service CVD Diamonds

As the only HPHT Service Provider in the USA, it offers its High-Pressure High Temperature (HPHT) Processing Service on CVD diamonds to its clients. Bellataire’s HPHT Processing improves the color grades of brown tinted CVD Diamonds. Bellataire’s main processing advantage over other HPHT services is that our process involves a High-Pressure Platform that provides the highest pressures used in HPHT processing. This helps us achieve virtually no surface burning, and most important, far less risk of breakage to lower clarity diamonds. Because of this, we have earned a reputation for the highest safety record among HPHT Service Providers.
