Comment: Opal is one of the most diverse gems out there. It's one of the few stones that looks just as attractive when it's crystal clear as it does when the stones are opaque. Despite it's rather simplistic chemistry, Opals show a great range of color in many varieties. This stone has a great mix of blues and greens in the gem. This stone is a doublet, which means it is set against a wooden backing to better show off the play of color.
Minerals: Opal (SiO2 n(H2O))
