0.5oz Natural Australian Opal Parcel, 6 Stones, Coober Pedy In The Rough. Good size stones all with colour. Three of them are big 18 to 21 cts and three smaller ones of 11, 8 and 5 cts. Full rainbow of crystal colours some with multi bars. 5 possible cutters and the smallest one is a maybe. When i say possible rough opal always curries a risk of cracking sand etc. These have the risk minimised by being cleaned up a little.
