When you buy HPHT diamond jewelry, you get a shiny and sparkly stone that is less expensive than natural diamonds. In addition, the stones contain metallic inclusions that enhance their sparkle. Since they share chemical properties with natural diamonds, they avoid environmental and ethical issues. This article will tell you more about the benefits of HPHT diamond jewelry. You will understand how these stones gain their luster and brilliance. And you will understand how they are made without sacrificing the high quality of a natural diamond.
Colorless diamonds
Diamonds that have no color are considered colorless. However, some diamonds may display a soft yellow or bluish tint. This colorless tint is completely safe and cannot be seen with the naked eye. The range of colors that diamonds can display is from D (nearly colorless) to Z (light brown or yellow).
A slight yellow or brown tint is not a desirable characteristic for a diamond. It may reflect less natural color. A stone that has no color or appears white is the ideal choice. Lab-created stones are not flawless and may have a slight yellow or brown tint. Ultimately, color is not as important as its clarity. A diamond that is colorless can be more expensive than one with a tint of a different color.
Produces diamonds
HPHT diamonds are created through two processes. The first is known as HPHT, while the second is called CVD. While both processes are technically colorless, the HPHT method allows for diamonds to acquire sparkle. This treatment produces diamonds that have a higher clarity grade. While most natural diamonds receive VS2 to VS1 clarity grades, colorless diamonds are nearly colorless.
Inclusions in HPHT diamonds are usually flux metals such as nickel or cobalt. The metals are usually present in a varying degree, and some of the largest metallic inclusions can be easily identified with magnets. Unlike natural diamonds, which don’t have metallic luster, HPHT diamonds are often opaque to visible light in both reflected and transmitted modes. Natural diamonds also have dark inclusions made of graphite or other minerals, but they don’t have a metallic luster.
Less expensive
The HPHT method uses a small seed of diamond as an artificial gemstone to grow larger gem-quality diamonds. The process uses 103-500 bar pressure and high temperatures over 1480 degrees Celsius to form a diamond around the seed. The newly formed diamond undergoes careful cooling to prevent inclusions. The inclusions in HPHT diamonds have metallic tints, but this isn’t a defect in the stone itself.
HPHT or high-pressure-high-temperature-processed diamonds are a sustainable, environmentally friendly, and ethical alternative to diamond jewelry. HPHT diamonds, also called CVD or synthetic diamonds, are created in a laboratory and have the same physical characteristics as natural diamonds. They are also more affordable than natural fancy color diamonds. Unlike natural diamonds, HPHT-processed diamonds will not chip or crack under everyday wear.
Natural diamonds
A natural diamond’s price is set by the big companies who mine it. However, the price of a lab-grown diamond is connected to its production. Because lab-created diamonds are created in a lab, their price is lower than natural diamonds. Moreover, they are as close as natural diamonds in every way – from their colors to their atoms. To distinguish between natural and lab-grown diamonds, one must use professional equipment.
A natural diamond has a faceted shape, and HPHT and CVD diamonds have cuboctahedron shapes. The natural diamond is oozing with diamonds, but large retailers have worked to restrict supply and drive up prices. By contrast, lab-created diamonds are cheaper and more ethical than natural diamonds. And because the two types are identical, you can’t tell the difference.
Circumvent environmental
HPHT and CVD processes require high temperatures and enormous amounts of energy to produce the precious gems. While some companies have tried to improve their safety and practices, the FTC warns that such claims should be viewed with caution. Nevertheless, they do mimic the natural process by which diamonds are created. This way, they avoid conflict and other ethical issues related to the production of diamonds.
Conclusion
The HPHT process tries to recreate the environment that produces natural diamonds, deep within the earth’s crust. Ultimately, this method produces diamonds that are more sustainable and humane than synthetic counterparts. But there are other environmental and ethical issues associated with diamond jewelry. Some jewelry manufacturers are committed to minimizing environmental impact and are working to produce diamonds that are free of contaminants. These concerns are understandable since diamonds are an expensive investment and are typically a significant financial investment.
