What Are HPHT Diamonds?
HPHT Diamonds are natural diamonds that have been treated using a process called HPHT, High Pressure High Temperature. HPHT mimics the processes that a diamond under goeas during it’s creation to elevate the color levels of a diamond. A light brown or yellow diamond may become near colorless using this process.
An HPHT diamond will sell for a significantly lower price than a natural diamond of a similar cut and color.
This is a permenant treatment and is required to be noted on the documents accompanying the diamond.
