This becomes the precious diamond for the dead body - Amazing Diamond Making System

The idea of wearing your deceased loved one around your finger or neck might be a little unsettling, but that's exactly what a company called Algordanza does: transform human ashes into a diamond. Diamonds are essentially just pressurized carbon atoms. When carbon atoms are exposed to extreme pressure and high temperatures, they stick together in an organized fashion to form crystals. One carbon atom covalently bonds to four others during this process, and the longer the carbon stays under extreme pressure and heat, the more carbon atoms will lock together in this rigid formation, and the bigger the diamond will be.
