And Plato once said ‘The Gods created certain kinds of beings to replenish our bodies they are the trees and the plants and the seeds.’ Another wise old Greek, Aristotle, made countless observations of nature, especially plants and their value in nourishing and healing. The ancient Greek philosopher Hippocrates once said, ‘Let food be thy medicine, and medicine be thy food’. Below is an example of an IGI report that verified that the diamond was grown through the CVD process.The Greeks certainly knew their stuff when it came to all aspects of health and wellbeing. The report should list how the diamond was grown. Look under the "Additional Information" section. You'll need to have your diamond's grading report handy. How Do I Know If I Have a CVD Lab-Grown Diamond? Lab diamonds grown through the CVD method are physically, optically, and chemically identical to natural diamonds. RELATED: What are Type IIA Diamonds? Are CVD Diamonds Real?Ībsolutely! A diamond grown through the Chemical Vapor Deposition method will still test as a diamond. CVD diamonds are not magnetic like HPHT diamonds can be. Type IIA diamonds are the most chemically pure diamonds – they lack nitrogen and/or boron impurities, unlike HPHT diamonds that are exposed to nitrogen. This can help scientists determine if a diamond is lab-grown or earth-grown. The CVD process produces Type IIA diamonds, which are extremely rare for naturally occurring diamonds. These carbon pieces become layered onto the diamond seed, which grows the diamond. The gas turns into plasma from these extremely high temperatures, causing the release of carbon pieces. This chamber becomes filled with carbon-rich gases and is heated to nearly 1500 degrees Fahrenheit. The CVD method places a diamond seed in a vacuum chamber. The CVD method uses less pressure than the HPHT method as well as smaller machines. The CVD method imitates how diamonds form in interstellar gas clouds. The CVD method was created in the 1980s, making it newer than the HPHT method. The CVD (Chemical Vapor Deposition) Lab Diamond Growing Method HPHT diamonds grow into a cuboctahedron, while CVD diamonds grow into a cube-like shape. It is then cooled and the diamond is formed.Ī rough HPHT diamond forms differently than a rough CVD diamond. The carbon melts and forms a diamond around the seed. The diamond seed is exposed to temperatures of over 2,000 degrees Fahrenheit and pressure of about 1.5 million PSI (pounds per square inch). The diamond seed is exposed to extreme heat and pressure, replicating the way diamonds are naturally grown underground by the earth. To grow an HPHT diamond, a small diamond seed is placed in carbon, the element that diamonds are made of. Outside of growing diamonds, the HPHT process can also be used to enhance the color of diamonds to make them colorless, pink, green, blue, or yellow. Gem quality HPHT diamonds were introduced in the 1950s. The HPHT method is the original method of creating lab-grown diamonds. But what are the differences between these two methods? The HPHT (High Pressure High Temperature) Lab Diamond Growing Method Lab-grown diamonds can be made from two processes: HPHT (High-Pressure High Temperature) method or the CVD (Chemical Vapor Deposition) method. If you own a lab-grown diamond or are simply searching for a lab-grown diamond engagement ring, you may be wondering how lab diamonds are made.
