Yes, the ALGORDANZA Memorial Diamond is a real diamond. It has the same chemical, physical and optical properties as natural diamond. In our laboratory in Domat/Ems, Switzerland we simulate these natural conditions with special HPTP (High Pressure High Temperature) machines. This is how your ALGORDANZA memorial diamond is allowed to grow in an individual and unique way. According to the ISO International Standard 18323 (2015), the memorial diamond grown at ALGORDANZA corresponds to a “laboratory-grown diamond”.
