HTPHT diamond is a real, natural diamond that has undergone a “High Pressure High Temperature” process to enhance its color.
The high pressure and 2300 degrees Celsius mimic the temperature at the Earth’s core and is considered a non-invasive, permanent process so that the beautiful results will last forever.
Less than 1% of all diamonds are suitable for HPHT treatment. In fact, HPHT treatment can only be used on diamonds with good clarity (typically, VVS2), because a diamond with inclusions can crack due to the extremely high pressure. This means your HPHT diamond was unique to begin with and born with impeccable clarity.
