The Ultimate Guide to HPHT Diamonds

HPHT diamonds are lab-created stones that are subjected to high temperatures and pressures. In the process, the temperature of the HPHT diamond can reach as high as 2,600 degrees Celsius. This high temperature and pressure simulate the heat produced by the earth and its minerals. The result is a colorless and lusterless diamond. The only way to tell if the diamond has been treated is through an advanced spectroscopy.

Made in high pressure and temperature

HPHT diamonds are made in a laboratory under high pressure and temperature, and are similar to natural diamonds. The high temperatures and pressure are produced by a special machine, which creates two times the pressure and temperature as the natural process. In each process, a seed of diamond material is placed in molten carbon. Under high pressure and heat, the carbon melts and forms a diamond around the seed.

Characteristics of a diamond

Diamonds are classified by the 4Cs, which are the four defining characteristics of a diamond. Despite their superiority over natural ones in the 4Cs, HPHT is not a perfect process. This process can cause multiple cracks in a diamond. It also requires expert supervision. Because the HPHT diamond is produced with less energy, it is usually less harmful to the environment. Nevertheless, it is best to check the official certification of any stone to make sure you are buying a genuine diamond.

HPHT diamond

Another important thing to consider when purchasing an HPHT diamond is its certification from the Gemological Institute of America. HPHT is considered a permanent treatment by the GIA and is not permanent. Therefore, if you are planning to buy a diamond, make sure you know its origin. Moreover, it is crucial to note that an independent lab can test a diamond for its treatments before you buy it. If your diamond is treated by an external lab grown diamonds, you will need to obtain an independent certification from the gemological institute of America.

Although HPHT diamonds have fewer inclusions than natural diamonds, they are still far from perfect. Compared to natural diamonds, HPHT diamonds are easier to produce and more expensive than naturally-occurring diamonds. They also have less glare and are much more durable. They have a higher price than natural diamonds. But if you’re interested in a real diamond, it’s worth it to pay a little more for the quality of the stone.

Synthetic compound

Although HPHT diamonds are not mined, they are made from a synthetic compound of carbon. Because the diamonds are synthetic, they are often better than natural diamonds. They are more affordable, environmentally-friendly, and are often regarded as superior to mined diamonds. A good choice if you’re looking for a high-quality engagement ring or a wedding band with a low price tag will be an HPHT diamond.

Using natural diamonds

HPHT diamonds are not created by using natural diamonds. This procedure is used to treat diamonds that have not fully crystallized when released by an erupting volcano. The process is a scientifically-controlled process that uses high temperatures and pressures to create a unique diamond. Unlike natural diamonds, HPHT ones are often set in jewelry rather than being loose. That means that they may be a little more expensive, but that’s how they’re created.

In addition to being more affordable, HPHT diamonds are also more environmentally-friendly than natural diamonds. The technology is a permanent way to alter the color of a diamond. By applying the same pressure and heat to it as the earth does when forming a diamond, it can bring it to a white color. With an HPHT process, the HPHT diamond will last forever. The same pressure that is used to form a natural stone will be applied in the HPHT process.


The HPHT treatment of a diamond is a permanent process that mimics the environment in which a diamond was formed. This process brings a candidate diamond to a mature state with a color grade of D or F, and finishes the natural maturation process. The benefits of HPHT include a more uniform color and clarity. This treatment is a better alternative to natural diamonds if you want to keep the price low.
