Diamonds - What is Diamond and How are Diamonds Formed?
- Hundreds of millions of years ago eruption of magma from the mantle propelled natural diamonds closer to the surface . The funnel-shaped areas carved out magma eruption known kimberlite pipes, named after the first formation in Kimberley, South Africa discovered . Gradually at the top of the tubes eroded below expose diamond . Erosion can also wear diamonds from its original location in river and coastal areas. In its crudest form, which means diamond ore does not look like the shiny nuggets on top engagement rings . Diamonds are sorted, cut and polished to bring out its luster . Diamonds are not created from the compressed trees and vegetation that coal produces as popularly believed .
- Experiments and the high density of the dots represent only can be molded together under tremendous heat and pressure . The only places where these conditions exist deep below the earth's surface, about 150 km to 200km (90 to 120 miles) in an area called the mantle beneath the Earth's crust where an abundance of carbon atoms . The pressure here in combination with temperatures between 900-1300 on the Celsius scale forced to crystallize together the carbon atoms in a cubic (isometric) arrangement creates diamonds .
