A classic, beautiful combination specimen from the Kelly Mine of New Mexico. Tiny, sparkly and gemmy, "rice-grain" smithsonite crystals are peppered on the banded, botryoidal, powder-blue aurichalcite that covers the gossan matrix crust. A really neat bonus feature on the backside are the rice-grain smithsonite crystals embedded in the starkly contrasting gossan matrix. Older material, 1960s or early 1970s material. Ex. Mullane Collection.
