White cloud-like Calcite crystals to 3mm covering the entire top of a piece of massive crystalline pink Baryte with a couple balls of Pyrite tucked away in the Calcite clouds. The labels say that this is Manganoan Calcite, however it is pure white (Calcite-Mn is typically pink) and although Mn might be present we have not confirmed it. Nice piece!
