Do lab grown diamond look different?
To the naked eye, lab diamonds look exactly the same as the mined
ones to even the most trained and experienced jewelers and
gemologists. Because synthetic diamonds have the same physical and
chemical properties as natural diamonds that cannot be discerned by
the naked eye alone. And lab created diamonds cut and polish
specifications, like natural diamonds, are also divided according
to the 4Cs. Therefore, to distinguish, experts need to use
specialized equipment to decipher the physical and spectral
differences with natural diamonds.
What is high pressure and high temperature?
HPHT, the full name is High Pressure High Temperature, that is,
high temperature and high pressure. To be clear, the term HPHT has
two concepts in diamonds: HPHT lab-grown diamond and HPHT treated
processed. For example, brown diamonds can be turned into yellow or
colorless through HPHT treatment.
Man made diamond by high temperature and high pressure method
refers to simulating the growth environment of natural diamond,
using graphite, diamond powder or graphite-diamond powder as the
carbon source, forming an equiaxed crystal in the growth
environment of high temperature and high pressure, metal catalyst,
etc., referred to as HPHT synthetic diamonds, or HPHT cultivated
diamonds.
