A delightful example from this locality consisting of well formed UV reactive Manganoan Calcite crystals which glow a delightful sweet pink color under long wave ultraviolet light. Specimens from this locality come from old miners and were found decades ago. Specimen comes from the historically mined but now closed and refilled upper levels of the Madem Lakkos deposit in Macedonia Greece.
Please note : Fluorescence is a phenomenon that causes a mineral to "glow" within the visible spectrum when exposed to ultraviolet light. Ultraviolet light is a form of electromagnetic radiation invisible to the human eye. The ultraviolet reaction is only visible with a special fluorescent torch / lamp with a filter that blocks white light but allows ultraviolet light to pass through. In order to achieve satisfactory results, do not use inexpensive 'UV' lights. Keep in mind that not only wattage, filtration but also distance from the UV torch to specimen are significant factors for best results.
Thank you for watching.
