2 · CVD-processed stones are much different from the natural diamonds produced by geologic forces. They are also vastly different from the High Pressure, High Temperature (HPHT) synthetics that have been manufactured since the mid-1950s. CVD synthetic diamonds began appearing in the gem diamond market about a decade ago.

There are two main lab-grown diamond production methods: the high pressure/high temperature process (HPHT) and chemical vapor deposition (CVD). Both methods are commonly used, but CVD is becoming more popular for producing gem-quality synthetic diamonds for jewelry. HPHT is used more often to create synthetic diamonds for industrial use.

2000s: Diamonds are created using the chemical-vapor deposition (CVD) method, which requires lower pressure and temperatures than the HPHT method. Mid-2010s: Colorless lab-made diamonds are available in the jewelry market in .
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.
The nature of inclusions in lab grown diamonds differ from those of mined diamonds and may be discerned under magnification (HPHT) and via advanced spectroscopy (HPHT and CVD). Because the flux metal alloy used for diamond growth in HPHT applications contains elements such as , nickel, and cobalt, HPHT synthetic diamonds often display ...

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.
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.
