This is a large, very rich specimen of Tsumeb smithsonite. In person, it has a pretty, light greenish-tan color that did not come out in the photo. The shiny crystals are just all over this 3-dimensional, limonitic matrix, filling its pockets and piled up on its projections. In fact, the contact is only on the bottom, and the specimen can be viewed from almost any direction showing off its sparkly 0.5-cm crystals.
