One of a kind lab grown diamond detection device that screens for CVD & HPHT lab grown diamonds, and natural diamonds enabling a user to know about their nature of origin with confidence. It can screen star, melee, pointer parcels, solitaire rings, pendants, and earrings within 10 seconds.
Process of growing HPHT vs CVD Lab grown diamonds HPHT. HPHT was the first method discovered and used in the process of growing diamonds. It aims to copy the natural diamond growth process. It involves placing a diamond seed in a carbon medium with a catalyst. Carbon is the building blocks of all diamonds whether earth mined or made in a lab.
The CVD method was created in the 1980s, making it newer than the HPHT method. The CVD method imitates how diamonds form in interstellar gas clouds. The CVD method uses less pressure than the HPHT method as well as smaller machines. The CVD method places a diamond seed in a vacuum chamber. This chamber becomes filled with carbon rich gases and ...

2021-11-9 · Lab grown diamonds, whether grown in with the HPHT or CVD method, have some key advantages compared to mined diamonds. Because of the high cost of mining and rarity of an earth grown diamond, man made diamonds are almost 40% cheaper than a natural diamond. Lab grown diamonds also come from a transparent supply chain and can be more ecologically ...

2016-7-25 · The growth chamber is heated to 1300-1600 °C with pressures above 870,000 pounds per square inch. The molten metal dissolves the high purity carbon source. Carbon atoms precipitate on a small diamond seed crystal, and a synthetic diamond begins to grow. The lab-grown crystal is then cut and polished by a diamond cutter.
This article reviews the main mistakes to avoid when buying a lab-created diamond: CVD – Avoid brown color hue. Avoid diamonds with strain lines that cause them to look fuzzy. HPHT – Avoid blue color hue ("blue nuance" or "faint blue"). There's a lot of variation in quality between CVD and HPHT diamond manufacturers.
