Diamond: the hardest raw material ever
Diamond is the hardest raw material ever found on earth. Diamond consists of pure carbon that crystallizes as a result of very high pressure and temperature. These conditions are only found at depths of 150 to 200 kilometers below the Earth's surface! The diamond is formed there, after which it finds its way to the Earth's surface through volcanic eruptions. With great effort, the diamond is extracted from the earth and expertly processed into gemstones for jewelry. Diamond mining is still very complicated today, despite all the modern techniques. On average, just over six tons of rough rock must be processed to find one gram of rough diamond! Of all diamonds only 20% is suitable for use in jewelry.
