This specimen consists of a thin layer of opal which covers one side of a flat, thin slab of a white, grainy, soft host rock. The opal is not more than 3 mm thick at any point, and is transparent and clear enough to see the host rock underneath. It is very colorful, with flashes of all colors visible depending on the angle of view. This layer of Opal is polished to a high gloss and is heavily cracked, though the material does not show any "crazing". A small piece near the center of the specimen has been chipped out, but the rest of the material is secure. I would not suggest trying to cut this piece into smaller portions, but one could make a large medallion or a brooch with some careful metalsmithing or wire work.
