Green blue dark opal, 3.62ct
Rich green rolls all the way over this opal. The play of color goes all through the stone and it could be classified as a crystal opal, however it doesn't have any translucency of crystal.
High dome accentuates the depth of play of color and makes this opal a real attention catcher.
This is the largest of four opals coming from the same piece of rough. I was holding for more than a year and half to that piece, just to figure out how to work it the best.
3.62ct, 11.55x8.83x5.81mm from Lightning Ridge, Australia.
