- Crystal Opal (Gemmy!)
- Gems and Jewelry, 22.0 x 10.6 mm; 4.73 carats
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 its rather simplistic chemistry, Opals show a great range of color in many varieties. This cabochon cut gem is what is often called "Crystal Opal," with a white background hosting flashes of greens, golds, oranges, blues, purples and reds. The stone shows a beautiful jelly-like appearance when backlit. In reflected light, it shows great color flash and this stone is a solid Opal, not a doublet or a triplet, which makes a difference in value.
