Quartz crystal is a member of the family, is one of the most common minerals. Usually formed in igneous, metamorphic and sedimentary rocks, the chemical formula Sio2, Mohs hardness 7, rhombohedral crystal ends were cylindrical or hexahedral cone angle, crystal and glass surfaces usually have shiny stripes, rich inclusions. In general, the more pure crystal in color, the more light, clarity, and the higher its value the higher refractive index.
The main components of the diamond carbon (C), with C content of 96% -99.9%. Even very pure diamonds also contain 0.001% of impurities. Diamonds in the impurity components are Si, Al, Ca, Mg, Mn, Ti, Cr, N and so on. In addition to N, the rest of impurities are usually in the form of mineral inclusions in diamonds often contain magnetite, ilmenite, pyrope, chrome diopside, olivine, graphite and other mineral inclusions.
Crystal Diamond specification 80MM * 60MM, Austria, cutting process, the quality comparable to Swarovski!
Special Note: Note that anti-stress, falls, to prevent the strong-chien.

The most common diamond simulants are high-leaded glass and cubic zirconia, both artificial materials. A number of other artificial materials, such as strontium titanate and synthetic rutile have been developed since the mid 1950s, but these are no longer in common use. Introduced at the end of the 20th century, the lab grown product moissanite has gained popularity as an alternative to diamond. However, unlike CZ and other diamond simulants, Moissanite is a naturally occuring gem that is ultra rare to find as it comes from meteorites, therefore it is more likely to be considered a diamond alternative rather than a diamond simulant.

Crystal Diamond is diamond produced in a technological process; as opposed to natural diamond, which is created in geological processes. Crystal Diamond is also widely known as HPHT diamond or CVD diamond, HPHT and CVD being the production methods, high-pressure high-temperature synthesis and chemical vapor deposition, respectively.
Both CVD and HPHT diamonds can be cut into gems and various colors can be produced: clear white, yellow, brown, blue, green and orange. The appearance of synthetic gems on the market created major concerns in the diamond trading business, as a result of which special spectroscopic devices and techniques have been developed to distinguish synthetic and natural diamonds.
