7.4 x 4.4 x 2.8 cm. An unusual locality piece with very attractive color, and sparkly as a bonus. The calcite druse covers small crystals (2-5mm) of malachite that are, themselves, are a replacement of previous azurite. It looks like some aurichalcite is present as well, by the powdery color. Ex. Harold Urish Collection.
