4 Types of HPHT Diamonds

Whether you’re looking to buy a natural or colored hpht diamonds, you may be wondering how they’re made. Here’s what you need to know. There are four major types of hpht diamonds, each with different costs and qualities.

Colored hpht diamonds

If you’re looking to buy a diamond, you can find many different types of colored diamonds. One type is a diamond that has been treated with HPHT. HPHT is a process in which a diamond is treated with a chemical that creates a color that appears on the surface of the diamond. These diamonds can be either natural or synthetic. The main difference between natural and synthetic colored diamonds is the method of treatment. HPHT diamonds can have a variety of colors, including yellow and blue.

HPHT is a process that uses high heat and pressure to treat diamonds. This process helps stabilize the diamond’s structure and promotes the growth of new crystal structures. This also helps to reduce the brown color caused by dislocations in the diamond. While the process can produce a variety of color results, it does not alter the clarity of the diamond. HPHT diamonds are not considered “clarity enhanced” by most grading laboratories.

HPHT diamonds can be a great way to purchase a high-quality colored diamond without breaking the bank. HPHT diamonds are GIA-certified and are suitable for sophisticated investors. HPHT diamonds are available in colorless and white grades, as well as many rare colors. They are often priced higher than other types of diamonds but can be very affordable.

GIA certified hpht diamonds

When buying a diamond, make sure the seller discloses if it is HPHT treated. HPHT is a process that aims to alter a diamond’s color. GIA considers this treatment a permanent process. Although it is impossible to visually check if a diamond has undergone HPHT treatment, an independent laboratory can verify it. GIA reports the treatment on the diamond’s certificate.

GIA’s DiamondView imaging technology has been used to distinguish between natural and HPHT diamonds for over two decades. This technology uses a sample holder and a high-energy UV source to view fluorescence reactions under the facet surfaces of a diamond. Although most HPHT synthetics exhibit no reaction to a long-wave UV light source, DiamondView imaging enables you to see the fluorescence reaction beneath the facet surfaces.

HPHT diamonds come in a wide range of colors. Previously, the majority of HPHT synthetics were yellowish orange or orangy yellow. Since 2007, they have been offered in pink, blue, and near-colorless color grades. Although the percentages have fluctuated over the years, the percentage of colorless or near-colorless synthetics has increased significantly and now makes up 43% of diamonds submitted to GIA.

Cost of natural hpht diamonds

There is a significant difference between the price of natural diamonds and synthetic ones. Natural diamonds have a higher price tag and are much rarer than lab-grown diamonds. On the other hand, lab-grown diamonds are much cheaper, and are ideal for jewelry. In fact, diamond jewelry is one of the most popular uses for synthetic diamonds. The most common example of this is hpht diamonds rings. Lab-grown diamonds are also sometimes used to make memorial diamonds, which are colored diamonds derived from a person’s ashes.

HPHT diamonds are created by pressing them into a brittle crystalline structure using a high-pressure, high-temperature process that closely mimics the conditions in which diamonds form. These synthetic diamonds are often cheaper than natural diamonds, and are a popular choice for buyers looking for the highest quality diamond at a reasonable price.

Conclusion

The cost of synthetic diamonds depends on the quality and setting. Natural diamonds have very little impurities, but lab-grown diamonds can have excess impurities due to metal influx during the manufacturing process. Excessive impurities will alter the diamond’s chemical composition and physical properties.
