2 pieces of genuine black diamonds, "matching pair". A black diamond is a genuine diamond where part of the carbon (the diamond is 100% carbon) has either remained uncrystallized in the chemical bond typical of a diamond, or where the diamond has partially returned to the graphite form of carbon due to changed conditions over the course of millions of years. Even a very small amount of ordinary carbon in the crystal structure of a diamond causes the black color. The chemical and physical properties of normal black diamonds are similar to ordinary colorless and transparent diamonds, but their optical properties are of course from completely opaque (opaque) to translucent or partially transparent. In online stores, you often see fake "Black diamonds" being sold, which in reality are, for example, black tourmaline or hematite. These are genuine natural diamonds, examined and verified by a GIA gemmologist! Weight: 0.52ct (pair) Dimensions: 2.7 x 4.1mm.
