A lovely little semi black Opal Solid from Lightning Ridge. This little one is super unusual, as right through the middle of the Opal, there is a dull stripe of grey... But either side of the grey, it is ELECTRIC green! And in the right lighting you can even see patches of blues and purples. It's yet another super unusual little one, but so impressive when you see it do it's thing! Claw set into a handmade Sterling Silver ring.
