6 Coober Pedy Seam Opal Rubs/Rough Parcel 12.06cts Multicolour Fires Australia

I have for sale a nice parcel of Rubbed/Rough Preform opals from Coober Pedy Australia. These weigh 12.06cts in total. They are Seam type material rubbed down, shaped. Light/Milky base crystal with Green/Pink/Orange fires over them. Some nice multicolour stones, 1 is very directional, and a bit duller. Will cut some nice freeforms, jewelery pieces. Thanks for looking.
