Nice Rough Koroit/Conglomerate Opal Rough 603.5cts Pods/Nuts/Patterns/Fires

I have for sale a nice quality Sliced and Rough Opal from Koroit, Queensland. This weighs 603.5cts and is 87x58x20mm. It is an end piece of the rock, so has a sliced face, and a rough side. Nice Gemmy little Nuts/Pods through this material, some bright Blue/Greens mostly. Some Opal showing on the skin aswell. It is a Superb Picture stone right there as it is, Specimen, maybe polish it up for a desk or similar.  Great item. Thanks for looking...
