2.45" Polished Yellow Dendritic Opal Slab - Western Australia

This is a beautiful slab of "moss opal" containing small, black dendritic inclusions. It earns its more common name, "dendritic opal" from these small black inclusions. This form of opal comes from the Eastern Goldfields of Western Australia. It's known to occur near the towns of Kalgoorlie, Leonora, and Norseman.

One side of the specimen has been cut flat and polished to a glossy finish.
