This Crystal Opal is from Coober Pedy, South Australia and has been cut to a trapezoid shape in order to retain the best of the play of color.  Weighing 12.31 carats with very bright Blue and Green colors, it has been highly polished and is now ready for a Custom Setting and no matter how you have this beautiful stone set, it is sure to be noticed. The video will give a better idea of the bright color and will also show there are no black edges as shown in some photos - they are merely shadows. One image shows the opal on a black background and how intense the color becomes if set this way.  Please allow at least 2 business days to ship this beautiful gem.
