The Growing

A natural diamond is generated from the carbon of vulcano ashes – about 200 km under the earth´s surface at very high pressure and very high temperature over a period of millions of years.

We simulate these conditions – approx. 60’000 bar and approx. 1’500° Celsius – and let the


developing process pass off in fast motion.

In order to create this unique and distinctive fire of your diamond we need parts of the ashes or parts of coat resp. plumage of your pet. The developing process is divided into different process steps which are documented in your certificate of genuineness.
