Diamonds are one of nature’s most precious and beautiful creations, it is also the most popular gemstone. But as the adage goes, nothing beautiful comes easy; Diamonds come from 90 - 120 miles below the Earth’s surface and a few have come from as deep as 500 miles below. Under immense heat and high pressure, carbon-containing fluids dissolve various minerals that result in diamonds’ beautiful and rare crystalline structure.
Diamonds are brought to the Earth’s surface through very deep-seated volcanic eruptions. Diamonds can also be found in three types of deposits: alluvial gravels, glacial tills, and kimberlite pipes. The kimberlite pipes form from the disturbance of magma into the Earth’s crust and deliver diamonds and other minerals from the mantle. Diamonds found in alluvial and glacial gravels are released by the geologic activity of the kimberlite matrix and then redeposited in rivers or in glacial till.
Diamonds were first discovered in India, they were the world’s original source of diamonds. India’s supply in diamond declined in the 1700’s and then Brazil became the world’s major source of diamonds, until the late 1800’s where South Africa discovered a huge diamond reserve. At present, diamonds are mined in different parts of the world, and we at Diamond Registry can bring you closer to them!
