How Diamonds Are Made

Natural diamonds are pure carbon crystals that are formed 100 miles or more deep within the Earth's mantle where extreme pressure and heat exist. The carbon that makes diamonds comes from the melting of pre-existing rocks in the Earth's upper mantle which are forced deeper down by temperature changes in the upper mantle. When pressure, chemistry and heat conditions are right, then the carbon atoms in the melting crystal rock bond together and as the temperature cools, the result is the formation of diamond crystals.

Laboratory grown diamonds in the Solaura collection are formed in the same way, under similar conditions to those found underground. These conditions are produced by specially built custom designed cultivators....more »
