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.
The value of the gemstones is determined by four (4 C) quality characteristics:
Cut / Clarity / Colour / Carat (the weight)
This is the type and shape of the stones. The cut enhances the shine and thus the optical effect.
The clarity gives information about inclusions of a cut diamond. The purer a diamond, the more it shines.
Diamonds with colors of high saturation such as pure red, green or blue are rare. These saturated colors are called “fancy colors”. Red and pink diamonds are the rarest.
The weight of individual diamonds is traditionally expressed in carats, a unit that corresponds exactly to 0.2 grams.
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.
