Nice Quality Boulder Opal Rubs/Preforms 33cts Queensland Australia Multicolours

I have for sale a nice parcel of Rough Rubbed/Preformed Boulder opals from Winton, Queensland. These weigh 33cts in total. Mixed Light/Milky and clearer crystal opal, Blue/Greens, also Multicolours stone with Pink/Red/Orange. These will clean up some great Ringstones and similar. All have fires to look at. Some nice pieces, some need more work that others. Thanks for looking.
