The name "diamond" comes from the Greek word, "adamas," for "unconquerable." Diamonds have been known and mined for thousands of years since they were first found in India earlier than 500 B.C. Diamonds were discovered in Brazil (South America) in 1729. They were also found in Arkasas, Borneo, Russia, Congo Republic (Zaire), Botswana, South Africa, Angola, Namibia, Ghana, Central African Republic, Guinea, Sierra Leone, Zimbabwe, Guyana, eastern Venezuela, Australia and The Northern Territories, Canada.
Diamonds were formed eons ago under incredible heat and pressure deep within the Earth: between 100 km and 200 km below the surface. All diamonds are at least 990,000,000 years old. Many are 3,200,000,000 years old (3.2 billion years) During the earths growing phase millions of years ago, great volcanic forces pushed the "blue earth" containing diamonds to the surface where they were scattered along rivers and into the oceans.
