HPHT
High-Pressure High-Temperature, or HPHT, recreates a diamond's natural growing environment found deep within the Earth.
The machines used have the ability to build up the pressure of almost 60,000 atmospheres and temperature of 2,500 degrees Celsius.
With the people's awareness of environmental protection increasing, synthetic diamonds are favored by more and more young people and jewelry manufacturers. Due to the environmental protection of synthetic diamonds is better than natural diamonds, we call artificial diamonds as green diamonds too. In addition, the cost of synthetic diamonds has dropped dramatically than before, which has played a great role in the flourishing development of diamond jewelry.
