This gem stone is very stable White Base opal, not a cracky opal, no inclusions, no sand or cotton on its face visible to the naked eye (please look at the images and movie very carefully to see if it is acceptable for your requirements). You must see the stone in real life. My images really do not do justice to the beauty of this stone. I mined this gemstone in 1995 from 17 miles field of Coober Pedy South Australia.
