Memorial diamond press

HPHT diamond press and technology help you preserve love and memories. Memorial diamonds, also known as genetic diamonds. By audience, they include pet diamonds, baby hair diamonds, and couple diamonds. By carbon source, they are classified as hair diamonds or cremation diamonds.

Lab-grown diamond press

HPHT diamond press and technology make your diamonds shine even brighter. High Pressure and High Temperature (HPHT) is a technology that simulates the natural diamond formation environment by depositing and growing carbon atoms into diamond crystals under extreme conditions.

Industrial diamond press

HPHT machine and technology make your cutting smoother. Industrial diamond classification Diamond single crystal and diamond powder. Polycrystalline diamond composite (PDC) is an ultra-hard composite material produced using a six-anvil press under high temperature and ultra-high pressure conditions.

Accessories

The main components of the hinge beam assembly are: the main beam of the hinge beam, Anvil, small/big pad, steel ring, steel cover/inveryed sleeve, piston. Among them, the anvil, the pad and the steel ring are vulnerable parts。Customers can select according to actual needs.

HPHT vs CVD Lab-Grown Diamonds 2026: CVD is cheaper and excels in larger sizes, but HPHT wins for superior quality consistency, long-term color stability, and minimal after-sales issues. A 10+ year jeweler’s honest take: HPHT’s ‘born beautiful’ nature (minimal post-processing) means true peace of mind—ideal for engagement rings. Budget buyers can opt for top-tier CVD, but prioritize HPHT for reliability.

Huanghe Whirlwind is a large state-controlled enterprise and a key high-tech company under China’s National Torch Program. It is a leading enterprise in China's super-hard materials and products industry.
HPHT diamonds and CVD diamonds are both laboratory-grown diamonds that have the same chemical and physical properties as natural diamonds, but are made using different methods. HPHT diamonds are grown at extremely high temperatures and pressures to simulate the natural diamond formation process, while CVD diamonds are grown at relatively low temperatures and pressures using chemical vapor deposition.
