ORIGIN : 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 fantastic example from the Madan ore field in Bulgaria consisting of a cluster of the highly sought after black tetrahedral Sphalerite crystals which are well formed along with terminated Quartz crystals and a single manganoan Calcite crystal. On the base specimen has manganoan Calcite which glows a delightful watermelon to coral pink color under long wave ultraviolet light (see photos). Specimen is very interesting under magnification as there are many features to explore, view the well formed Sphalerite crystals with the delightful growth habits up close along with the micro terminated Quartz. Although crystals are obvious to the naked eye, specimen requires magnification in order to enjoy the range of interesting structures. Specimen will look delightful on display. Buyer will not be disappointed. Will be a wonderful 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.
