Gem 2119 Paraiba YAG

Cushion
  • Gem 2119 Paraiba YAG

3.985 ct. YAG Pariaba Color

This year in Tucson, I bought a small amount of this material. The crystal is lab created YAG. Yttrium-Aluminum Garnet is the Y3Al2(AlO4)3 oxide, which has a cubic crystal structure of natural garnet. Therefore, YAG is simply called a synthetic garnet. This new color simulates a fine Paraiba type tourmaline, but with the properties of a garnet. Hardness is 8.5 and the refractive index is 1.82 both of which are higher than tourmaline. The higher RI and dispesion make for a more stunning stone than tourmaline could be. The photo doesn't do the color justice, as it has more pop and glow in person. Measures 8.191 mm cut in a square cushion design.
