Man Made Diamonds
Is a HPHT diamond a real diamond?
Yes.Both cvd diamonds and hpht diamonds are real diamonds. Although
they are both grown in the laboratory, they are gem-quality
diamonds. Their element structure and physical, chemical and
optical properties are the same as natural diamonds, so they are
all real diamonds.
What is the HPHT diamond
HPHT is short for High pressure-high Temperature treatment. Its
purpose is to change or improve the natural body color of certain
types of diamonds to make them more valuable.
HPHT stands for high pressure and high temperature method, one of
the main methods used in laboratories to make diamonds. The diamond
growth process involves exposing carbon to extreme temperatures and
pressures that mimic the extreme heat and pressure conditions in
which natural diamonds form deep inside the Earth.
The diamond seed is placed under specially engineered pressure
conditions. Heat the growth chamber to 1300-1600 °C at a pressure
of more than 870,000 pounds per square inch. The molten metal
breaks down high-purity carbon sources. Carbon atoms are deposited
on a small diamond seed, and the synthetic diamond begins to grow.
This lab-made crystal is then cut by a diamond cutter and grinder.
