Description
This is actually 2 different genrations and forms of calcite. The base is actually a very, very pale manganocalcite as it has a very faint pink hue to it, and it is comprised of hundreds of flattened, disc-like calcite crystals. The spire growing up from the base is a more pure-white calcite with some interesting steps that look almost plant-like. The specimen appears to be a complete floater with no damage as there is crystallization all around it and no evidence of a contact point. Both forms of calcite glow bright orange under long-wave UV.
