Diamond is the hardest mineral we know and therefore the stone that best withstand use. It is also the only mineral that consists of only one chemical element: carbon. Name diamond comes from the Greek word adamas which means invincible. Most diamonds found in nature are between one to three hundred billion years old. The first diamonds were found in the Golconda region of India for about 4000 years ago.Diamonds are pure carbon that crystallized under a pressure of 70,000 kg/cm3 and a temperature of up to 2000 ° C. Such conditions exist 150 to 200 km under the Earth's surface. Volcanic eruptions drive the diamond toward the soil surface. 80% of all diamonds are unsuitable as a jewelry stone.
