Nice Qld Boulder Opal Rub/Freeform 22.52cts Nice Fires/Multicolours Unusual Shape

I have for sale a nice Rough/Preformed Boulder Opal from Queensland Australia. This one weighs 22.52cts and is 34x13x8mm. Its a weird shape, like a Keyhole, and waves, so has a bowl in the middle, and the ends go wider and thicker. It does have Multicolour Fires across the face. Some of the Black specks are Marker pen and will come out,  there may be a couple of sandspots to work out of it. A dremmel is essential to finish this one. Will make a great pendant once cleaned up. Thanks for looking.
