Diamond
Diamond (also called Diamond or Diamond) is a transparent gemstone that is the crystal form of the hardest carbon and natural substance on earth.
Diamond Stone is not only valuable and well known for its exceptional hardness, but also its high refractive index (brilliance) and high dispersion rate.
Although white or transparent white diamonds are the most popular, while yellow and brown (Champagne and Cognac) are actually the most common and numerous. Other colors can be blue, pink, red, green, orange, and black. Red diamond stone is actually one of the rarest gems in the world, because its color is not due to chemical traces like in most other colored gemstones, but because of the result of a small unique "defect" in its crystal lattice.
