What is a Memorial Diamond?
Natural diamonds are formed by high temperature and pressures on carbon in areas deep underground. A memorial diamond is formed by the carbon extracted from cremation ashes and subjected to laboratory controlled high temperature and pressure environments.
The resulting synthetic diamond is as hard and brilliant as a natural diamond, and is backed with a diamond guarantee certificate.
