BOULDER OPAL SLAB 2
A rare rough Queensland Boulder Opal Slab 2. You almost never get unworked pieces like this for sale. Really this is a gem in the rough. Features ethereal streaks of colour on a white background, wrapped in its sandstone host rock. I’ve done my best but it does look so much better in person. Polished up of course it will look absolutely stunning. A great project for the lapidary or opal enthusiast or jeweller or it could be for a collection. A super piece!
