Nice Rough Pipe/Boulder Fossil Opal split 233cts Green/Blue/Pink/Gold Fires

I have for sale a Nice Rough Boulder/Pipe Opal Crystal Split from Opalton, Australia. This one weighs 233cts between both pieces. Nice Crystal opal wit multicolour fires through it, also some Sand/Blob in the middle. The colour may well go under the sand, but you will need a careful dremmel. Or keep as a specimen pair. Thanks for looking
