2021-7-18 · Source: Gems & Gemology, Fall 2016, Vol. 52, No. 3. It's easier to find a VVS diamond among CVD diamonds than among natural diamonds. An analysis of 1000 diamonds in each of the three categories shown in the graphic above conducted by GIA and published in Gems & Gemology, Fall 2016, Vol. 52, No. 3 found that just over 25% of CVD diamonds could be given clarity grades of VVS2, .
2021-11-1 · A CVD diamond begins as a thin slice of diamond seed, which is often an HPHT diamond. The seed is placed in a sealed chamber and exposed to intense heat around 800 degrees Celsius. The chamber is filled with carbon-rich methane and other gasses that are ionized into plasma using technology similar to microwaves or lasers.
HPHT is a diamond color enhancement process performed only on rare Type 2a diamonds with the highest structural integrity and clarity grades. The process mimics the same geological conditions the earth uses to uncover colorless and white diamonds.

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.
Buy now Engagement Diamond Cluster What is lab created diamonds There are several ways to get lab created diamonds. One of the most recent and advanced is the HPHT technology. HPHT stands for high-temperature high pressure. In the laboratories, specialists recreate the conditions under which natural diamonds are created at a depth of 200 km.

The HPHT process has two applications in diamond production: (1) lab diamond creation; and (2) color enhancement or color altercation of natural diamonds. Growth of an HPHT diamond takes place in a small capsule which is positioned in an apparatus capable of generating very high pressures. Diamond powder dissolved in a molten metal flux is used ...
