Yeah, sooooo....marbles just don't get much more perfect than this!! A stunningly perfect opal cube is encased deeeeeep down inside this wildly beautiful PERFECT rainbow fumed vortex, with crushed opal shards glinting and gleaming all through the design. Then the backside is soooo flowing and beautiful!! This is just a stunning example of what a vortex can aspire to! Signed 'RR 20'.
