The emergence of diamonds

Millions of years ago, diamonds were formed deep inside the Earth. Often hundreds of kilometres below the earth’s crust, under glowing heat and enormous pressure, the carbon atoms combine to form fine crystal lattices and form a rough diamond. When a volcano erupts, the rough diamonds are transported to the earth’s surface.

Certificate

A certificate, such as the GIA certificate, is, so to speak, the identification of a diamond and therefore very important when buying. It proves the identity and the value of the stone and provides information about origin, authenticity and all extraordinary value-determining characteristics. With the certificate your diamond can be identified and evaluated again and again.
