MANGANOAN CALCITE AND QUARTZ SPECIMEN

Many photos and a video from all sides of the specimen taken in natural daylight. What you see is what you will receive, no surprises.

ORIGIN : BORIEVA MINE, MADAN, BULGARIA

Madan, in the Rhodope Mountains of Bulgaria, just north of the frontier with Greece, is an ancient ore-miners’ settlement. The history of mining in the Madan region extends back at least as far as the Thracians in the fifth century B.C. where the extraction of lead ore began.

A splendid example from the Madan ore field in Bulgaria consisting of well formed UV reactive Manganoan Calcite crystals which glow a delightful sweet bright neon watermelon pink to coral pink color under long wave ultraviolet light (see pictures) on sharp terminated Quartz crystals. Specimen is very interesting under magnification as there are details to explore. A wonderful specimen that the Madan ore field is known for. Will be a delightful addition to any mineral or rock collection. Do not miss this opportunity.

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. The UV longwave torch I use to take the photos with is a Convoy S2+ Nichia UV 365nm LED Flashlight with filter lens. Keep in mind that not only wattage, filtration but also distance from the UV torch to specimen are significant factors for best results. Use protective UV-absorbing goggles, for extended viewing.
