8.25 carat Lightning Ridge crystal opal, oval


Stunning large oval cut crystal opal from Lightning Ridge. Love the beautiful light blues and greens reminds us of a tropical sea. Small clean out spot on the back of the stone, see video. Very clean crystal Opal.

Please note blue colour is slightly lower in brightness than the pictures show, this is due to the camera seeing ultra violet end of the spectrum that we can not.  Still a very bright opal though, set with a solid back setting it will shine just as bright.
