Seller: rock-n-mineral (157) 100%, Location: Huntfield Heights, South Australia, Ships to: AU & many other countries, Item: 112079270926 140g Australian opal specimen This is a nice treated specimen of Australian Andamooka opal. The colours to be seen are mainly greens and blues. To obtain a darker background you will need to treat again. The opal is easier to see when the white base rock is carbonised which causes the white base to go a black colour. There are different ways to do this and you can look it up on the web to view different practices. Note: Photos taken late afternoon on an overcast day with both dry and wet shots of the specimen. Photos help form a description so please view carefully and ask questions prior to bidding or purchasing. Approx 50 x 40 x 35mm @ 140gYes, I can combine posting.
