All the fancy color diamonds we have here at VMK are accompanied by a Gemological Institute of America (GIA) report, and are all natural color. To understand how colored diamonds are formed, we need to understand how the standard white diamond is formed. Diamonds are formed when pure carbon is put under the extreme conditions of heat and pressure about 90 km under the earth's surface.
Diamond cutting requires a combination of technical mastery and artistry. The skill involves understanding of how the light passes through the diamond, in order to cut in a way that will enhance its natural beauty.
Diamond carat weight is the measurement of how much a diamond weighs. A metric "carat" is defined as 200 milligrams. A single carat = 0.2 grams.
The clarity of a diamond is a measure of the presence of inclusions and blemishes on the stone. The GIA rates clarity on a scale of Flawless – no inclusions or blemishes visible under 10x magnification, to Included – where inclusions are obvious under 10x magnification.
