It takes billions of years for Mother Nature to nurture and define naturally occurring diamonds into beautiful and one-of-a-kind shapes. The formation of diamonds takes place in a layer known as the mantle, which is present 100 miles deep within the Earth. Here, extreme pressure and heat combine to modify graphite on an atomic level into mesmerizing shapes of carbon we know as diamonds. Nature then helps move these gemstones from the deep depths of the earth through to the surface through unique volcanic pipes known as kimberlite pipes.
The natural combination of carbon dioxide and magnesium then compel the carbon rich magma to the surface which causes violent volcanic eruptions, depositing diamond rich magma across the volcano’s surface and further beyond into seabed, rivers, etc.
