WebOne of nature’s most unique and dazzling gifts, diamonds come from two types of deposits. Primary deposits generally consist of diamond-bearing “pipes” of a volcanic rock called “kimberlite.”. From deep in the earth these deposits were carried to the surface in molten rock, known as magma. Secondary deposits, also referred to as ... WebMar 30, 2016 · Extraction usually involves diamond-bearing ore and gravel. Once these materials are brought to the surface, metallurgists then extract the diamonds from the host ore. Diamond recovery requires a sophisticated system that has evolved greatly over the years and which benefits from today’s advanced technology.
