I have for sale 2 nice Boulder Opal Rough/Split Specimens from Winton, Queensland. They weigh 400cts in total. These are Ironstone base with Crystal/Milky Opal on the top face. There is one vien with slight greens. The half bowl shaped stone has lots of multicolours running around the opal. Pink/Gold/Orange/Greens, Turns more potchy/caramel, no colour in one corner. The face is not flat, stepped opal, could get some Small Cabs if sliced/diced up. But i think clean up as a specimen. Patch of colour on one side too. The second piece has some lovely pastel Bars/mixed pattern and Fires with some Caramel potch lines aswell. Some natutal fractures in a few places and a pit.  Both great specimens, maybe clean up for cabinet display or try and cut them. Thanks for looking.
