Once in the collection of the Seaman Museum, this is a plate of prized Bisbee azurite crystals, razor-sharp, a fine deep blue, measuring to about 0.75 cm. These crystals are beautifully isolated on the limonite matrix, and scattered around them are tiny little green puffballs of malachite! Some of these little puffballs are actually on the azurite crystals. There are a few contacts but they are very hard to see. 8.0 x 5.9 x 2.1 cm
