COLOUR-ENHANCING DIAMOND TREATMENTS - HIGH-PRESSURE, HIGH-TEMPERATURE TREATMENT (HPHT)
As the name refers, HPHT is a technique to turn yellowish and brownish diamonds into colourless stones by heating them under high pressure.
This type of colour enhancement is permanent, meaning the colour of the stone does not revert to its original state.
HPHT treatment can be hard to detect that’s why the Federal Trade Commission (FTC) requires it to be explicitly disclosed.
Grading reports issued by the Gemological Institute of America (GIA) always contain a note about HPHT treatment if detected. In some cases, treated diamonds may also have a laser inscription indicating the treatment.
It’s important to understand that not all grading labs include inscription and mention of the treatment in their certificates. That’s why it’s useful to ask the seller about the labs they use for grading.
