Diamond has been recognized as the gemstone coupled to the month of April on many dated and modern birthstone lists. But the allure of diamond was treasured and collected long before it was crowned the birthstone of April. Diamond is found in many fascinating and differing locations from Siberia to remote parts of Africa.
Before the twentieth century there was little scientific knowledge known about diamond, though its beauty and oneness had been prized for centuries. Diamond knowledge has grown since then with research in chemistry, physical gemology, mineralogy and oceanography. Scientists have discovered that diamonds form under conditions that are only possible 100 miles underneath the earth’s surface. Once they are transported closer to the surface, tons of soil and hours of labor are still required to discover a few diamond crystals. The conditions for diamond growth are only found in certain parts of the world and listed below are the most important diamond deposits.
- Canada – Locating the diamonds that lay under the frozen soil in Canada took many decades. But after finally finding deposits in the 1980s, diamonds are being mined from several important sites. Canadian diamonds are known for their high quality.
- Guyana – Guyana’s diamond production is mostly small scale operations through alluvial sources.
- Brazil – Large, fine quality, sometimes fancy colored diamonds are mined in Brazil, though their operations are mostly small scale. Brazil was a leading supplier of diamonds before larger deposits were found in South Africa.
- Sierra Leone
- Congo – Diamonds mined in the Democratic Republic of Congo come from both alluvial and underground deposits. Most diamond unearthing is done in small operations with shovels.
- Tanzania – The Williamson mine in Tanzania is currently the most sophisticated and largest mining operation in the region.
- Namibia – Diamonds are currently being mined in Namibia through a joint operation with De Beers.
- Botswana – Botswana is a leading source of gem-quality diamonds in the world. Not only are diamonds mined in Botswana, but the country has created a diamond headquarters, Debswana, that also sorts and values gemstones mined there. This collaboration with De Beers benefits the people by creating many jobs for the middle class.
- South Africa – The diamond rush of 1869 was kick-started with the discovery of sources in South Africa. The country has become the birthplace of modern diamond manufacturing and is the world’s leading producer of the gemstone. The world’s largest rough diamond to date was unearthed in South Africa in 1903. The Cullinan weighed 3,106 carats rough and was cut into 9 larger finished pieces and 96 smaller brilliant cut diamonds.
- India – Until 1730 the only known source of diamonds was the Golconda region in south India. These mines are long since depleted and India’s current sources of diamonds are small deposits.
- Australia – The Argyle mine in Australia has been the world’s largest producer of diamond to date by volume. The mine is also known of its fancy colored pink, red and brown diamonds.
- Russia – A significant source of Russian diamonds comes from the Yakutia region of Siberia. Russia is a leading supplier of diamonds though most of their gemstones are smaller in sizes than their African counterparts.
