3 Nice Rubbed/Roug Coober Pedy Seam Opals 12cts Multicolour Fires Australia

I have for sale 3 Nice rubbed/Preformed Seam Opals from Coober Pedy Australia. The weigh 12cts in total. They are Crystal/White/Milky Base material all with Fires over/through them. Nice Gold/Blue/Red/Green Flashes when moved. One is a nice domed shape with lots of colour. Some slight inclusion lines aswell. Then a Pink/Gold dominant piece, Lighter base. Last has a rubbed out bar on the top. These are great Specimens as they are, but once polished will make nice Pendants and similar.  Thanks for looking,.,.,.
