2019-6-5 · The oldest of these is High Pressure/High Temperature (HPHT) manufacture wherein a diamond seed is nestled in carbon and one of three types of press is used to build up the seed. Whether using a split-sphere press, a cubic press, or a belt press, .
2021-6-15 · HPHT vs CVD Diamonds. The main difference between HPHT vs CVD diamonds is the way they grow or their morphology. HPHT diamonds grow in cuboctahedron shape and have 14 growth directions, while CVD diamonds grow cubic and have 1 growth direction. In comparison, natural diamonds grow in octahedron shape and have 8 growth directions.
CVD diamonds are grown in a lab and are made from the element carbon, just as an Earth-formed diamond is. This is important to point out because some newcomers believe that lab grown diamonds are "synthetic", like cubic zirconium or moissanite loose stones. But that's not true. CVD diamonds have an edge when it comes to cutting and polishing.
