Diamond Production

Lab-grown HPHT (High Pressure High Temperature) diamonds are created in a controlled laboratory environment that replicates the natural conditions under which diamonds form in the Earth's mantle. This process involves placing a small diamond seed in a chamber with a carbon source, like graphite. The chamber is then subjected to extremely high temperatures and pressures, mimicking the natural diamond-forming environment.

Brief Introduction:

Lab-grown HPHT (High Pressure High Temperature) diamonds are created in a controlled laboratory environment that replicates the natural conditions under which diamonds form in the Earth's mantle. This process involves placing a small diamond seed in a chamber with a carbon source, like graphite. The chamber is then subjected to extremely high temperatures and pressures, mimicking the natural diamond-forming environment.


Over a period of days or weeks, the carbon atoms crystallize around the seed, gradually forming a larger diamond. HPHT diamonds are chemically, physically, and optically identical to their natural counterparts. The only difference lies in their origin – they are cultivated in a lab rather than mined. This makes them a more environmentally friendly and ethical choice, as they do not involve the extensive mining operations associated with natural diamond extraction.

Diverse Press Equipment:

Our product line encompasses presses ranging from 420 to 1250 in cylinder diameter, with single-cylinder thrusts from 14,000KN to 116,000KN. The diversity and flexibility of these machines enable us to produce diamonds of various specifications and models, including cultivated diamonds ranging from 1 to 8 carats and even larger.


Utilizing our own high-efficiency, stable presses, we have established a professional workshop for the production of cultivated diamonds and diamonds. Here, we successfully produce high-quality diamonds of various carat weights under precisely controlled high temperature and high-pressure conditions. Our technology even allows us to produce large diamonds up to 12 carats, demonstrating our leading position in this field.

Guiye Company possesses a strong technical team and advanced production equipment. Our technicians have profound professional knowledge and extensive practical experience, ensuring efficient production processes and high-quality products. Our equipment is industry-leading, capable of efficiently and stably meeting various complex and special production demands.
