Diamond and coal are at the opposite ends of the price spectrum yet both are constituted from carbon, such are the miracles of nature. Man has been fascinated by diamonds ever since he discovered them; he has even shed blood to acquire more. Their beauty and rarity make diamonds desirable and valuable. Superior hardness, corrosion resistance, optical properties and thermal conductvity make diamonds suitable for many industrial applications. Modern technology has made it possible to produce synthetic or man made diamonds.
Synthetic diamonds help narrow the deficit between demand and supply. The understanding of the geological processes that forms diamonds have enabled scientists to develop techniques to manufacture man made diamonds. It is now possible to produce synthetic diamonds that are so similar to natural diamonds that even experts have difficulty telling them apart. They find use in jewelry and are much cheaper than natural diamonds but just as beautiful.
Man made diamonds were principally developed for industrial application as cutting tools and abrasives. Diamond production technology has matured over time and now it is possible to produce flawless man made diamonds suitable for use as gemstones. Synthetic diamonds are much cheaper than their mined equivalents and they are not tainted by blood or exploitation generally associated with mined diamonds.
Gemstone grade man made diamonds are mostly produced by Chemical Vapor Deposition (CVD) and High Temperature High Pressure (HTHP) processes. Diamonds are produced by the HPHT process by treating carbon or graphite under high temperature and pressure. CVD involves chemical reactions between precursor gases to deposit diamond crystals over a seed. The common colors are yellow, blue and colorless.
CVD polycrystalline, CVD single large crystal, HPHT grit and HPHT single large crystal are the four main types of artificial or man made diamonds. HPHT grit and CVD polycrystalline diamonds are very small are mostly used for industrial applications. Their major use involves cutting, drilling tools and abrasives. Single large crystals are diverted for use in jewelry and decoration. Synthetic diamonds are used in engagement rings and other diamond jewelry and are available at most jewelry stores.
