HPHTtreated

HPHT treated refers to diamonds that have undergone a process known as High Pressure, High Temperature. This treatment is applied to natural diamonds that have been identified as having less desirable color grades, typically in the yellowish or brownish range. The HPHT process aims to improve the color by exposing the diamond to extreme pressure and heat, mimicking the conditions under which diamonds are formed naturally. This process can sometimes cause the diamond to appear closer to a colorless grade.

The HPHT treatment is a recognized and widely used method in the diamond industry. It is important for consumers to be aware that HPHT treated diamonds are different from natural, untreated diamonds. Reputable gemological laboratories and diamond dealers disclose whether a diamond has been subjected to HPHT treatment. This disclosure is crucial for consumers to make informed purchasing decisions and understand the value of the diamond. The technology used for HPHT treatment involves specialized equipment that can generate pressures exceeding 50,000 atmospheres and temperatures above 1500 degrees Celsius. The duration of the treatment can vary depending on the specific diamond and the desired outcome. While the treatment can significantly alter the color of a diamond, it does not change its clarity or carat weight.
