Rough TGG Lab Garnet, Rare Magnetic Scientific Crystal Size:7-8g with an RI of 2This is rough terbium gallium garnet aka TGG. Rough pieces are sorted by gram size, with representative photos of crystals on a 1 mm grid. TGG is a very cool synthetic material. It has the same structure as a natural garnet, but has a composition that would never be possible in nature. The result is a bright and very dispersive gem with optical properties similar to diamond (cubic crystal structure with a lower RI but the same dispersion as diamond),
