Green dark crystal opal, 1.25ct

It looks like this opal has a green sparkling tread woven in it. The dark body tone accents the play of color.

This is one of four opals coming from the same large 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.

1.25ct,  12.22x5.55x2.83mm from Lightning Ridge, Australia;
