Mined high pressure high temperature (HPHT) treated diamonds have become increasingly popular over the years due to their unique characteristics and beauty. HPHT diamonds are natural diamonds that are subjected to intense heat and pressure to reveal their true color. In this blog, we will discuss what HPHT diamonds are, how they are made, and their characteristics.
What are HPHT diamonds?
HPHT diamonds are natural type IIa crystal diamonds that are mined from the earth and then subjected to intense heat and pressure to reveal the color they should have been. These diamonds can come out of the earth looking yellowish or brownish in color. This color is caused by a misalignment in the crystal structure and is very different then 98% of mined diamonds that have nitrogen causing the yellow color.
The process involves placing the diamond in a chamber filled with a metal solvent, such as iron or nickel, and then heating it to extremely high temperatures of up to 2,200 degrees Celsius. This process causes the metal to dissolve around the diamond, altering the crystal lattice into the corrected position allowing the diamond to be what it should have been from the earth.
How are HPHT diamonds made?
HPHT diamonds are made using a process that involves three main steps:
1. High Pressure: The diamond is placed in a special chamber and subjected to intense pressure of up to 1.5 million pounds per square inch (psi).
2. High Temperature: The diamond is then heated to temperatures of up to 2,200 degrees Celsius.
3. Diamond Enhancement: During the heating process, the metal solvent is introduced to the diamond, which reveals its color.
The result is a diamond that looks as it should have from the earth.
Characteristics of HPHT diamonds
HPHT diamonds have several unique characteristics that set them apart from other diamonds. The most notable of these are:
1. All HPHT mined diamonds are type IIa crystal which means they have no nitrogen and therefore should not have a yellow color.
2. Diamonds that can go through the HPHT process are typically high in clarity which allows you to own a naturally gorgeous diamond that is more rare than 98% of all mined diamonds.
HPHT diamonds are natural diamonds that have been treated to reveal their true color. They are not synthetic or lab-grown diamonds. This means that they are still subject to the same certification process as natural diamonds, and are graded on the same criteria of color, clarity, cut, and carat weight.
In conclusion, HPHT diamonds are natural diamonds that are subjected to intense heat and pressure to shoe their true color. They are known for their vivid colors, and increased value, and are a popular choice among jewelry enthusiasts.
