Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) is a colorless synthetic crystalline material of the garnet group, with good mechanical, thermal, and optical properties. It has cubic lattice, density 7.08 g/cm3 and Mohs hardness is variously noted as 6.5 and 7.5. Single crystals are made by Czochralski method and can be made with addition of various dopants for modification of color. It is used in fabrication of various optical components and as substrate material for magneto–optical films (e.g YIG and YAG).
