WebGadolinium and gallium are much more expensive than yttrium. However, with a dispersion close to diamond (.044), GGG makes a wonderful substitute. As with YAG, the dopants used for coloring are also responsible for the wide range of refractive index and specific gravity. Colorless GGG is near the bottom of each property.
