2 Nice Koroit Opal But/Sliced Rough Specimens 190cts Red Fires/Patterns Qld Au

I have for sale  2 Nice Rough/Sliced Koroit Opal specimens from Queensland Australia. These weigh 190ct sin total. They are Hard Ironstone base with Nuts/Halfs/sections in them. Chunkier/Deeper one has some Nice Red/Blue Fires around the core or Reddish ironstone, pattern around it.  The thinner slice has a Very nice Nut showing on one side, but not the back, so that skin/Colour/pattern will follow through the piece, but will be quite thin once finished.. Great lot, specimens or clean up Freeforms,.,.
