Two natural Australian opal rough cuts with some pre-shaping done and some lovely opal colour. One is a dark blue opal with some interesting dark green and purple opal colour, and the other is a dark crystal opal which shows some green, purple-blue and some gorgeous orange opal colour! They both have some cab on them but appear to also have good solid opal and may be suitable for cutting and polishing, and /or jewellery making. They are both about 20mm in length. Please look through all the photos as the main photo is rubbish! Add them to your collection today! From a Jeweller's estate, who sourced all his opals direct from the opal fields in the 1970s-1980s, and supplied in-trade customers around New Zealand. See my other listings for more delightful opals.
