Specimens of Fluorescent Mangano Calcite, in tumblestone form. Mangano calcite is a pink variation of calcite, due to the prescence of manganese. These specimens display excellent fluorescence, turning a bright orange when presented with shortwave UV light. These tumblestones may also display visible banding. These specimens measure between 1 – 2″ approximately and come in a white card tray with an information label.
