RARE Translucent Blue Cube Fluorite with Calcite 482 Gram Fluorescent Crystal Mineral Specimen Pakistan #303Locality: Baluchistan Fluorite Mine, Pakistan
Weight: approx. 482.68 Grams
Measures: 4.5\'\' x 3.5\'\' x 2.65\'\'A rare Fluorescent Blue Cube Fluorite Specimen with fluorescent Scalenohedral Calcite crystal formations from Baluchistan Pakistan. This high grade blue fluorite specimen from Pakistan displays an interesting crystal formation, shrouded with clear Scalenohedral Calcite crystal terminations and cube clusters on 2 sides! There is also no damage noticeable to the naked eye!The interesting cube display has well defined intricate layers of miniature Tetris-like stair stepped formations. This distinct texture, where in this case most likely due to etching, hundreds of minute steps and edges formed as a result of some type of natural erosion process that removed mineral grains in the Fluorite gradually; creating these bizarre mesmerizing surface effects. There is also a cave-like structure which only adds to appealing aesthetics, loaded with stepped habit from top to bottom! Adding to all these amazing attributes, is this specimen\'s brilliant fluorescence of electric blue and the bright orange glow from the calcite crystals, which look like tiny incandescent light bulb\'s electrified filaments! Truly an amazing 3 dimensional specimen! A fabulous addition to any fluorescent collection!Note: Be aware that being able to view fluorescent minerals requires an ultraviolet (UV) lamp. A LW UV 365nm was used for this specimen. A black light is not a UV light and in most cases fluorescent minerals will not fluoresce with a black light. ***I photographed this piece in a completely dark room using a Sony Alpha 7III DSLR Camera with a Sony FE-90mm Macro G Lens, and 3 - LW UV 365nm flashlights with included ZWB2 black filter glass all positioned strategically. This gives me complete UV light coverage of the specimens I photograph for my listings.
FYI...If you aren\'t using quality UV lights with filters to fluoresce any UV reactive specimens that you purchase from my shop, your results will vary.
In short, you need a quality UV flashlight that emits a high-intensity ultra violet wavelength. But the light also needs to have a high quality ZWB2 or Hoya glass filter to allow the transmission of pure UV light through the filter while restricting natural light absorption. A dark room is also necessary for the best UV reaction.
(Be aware that lower quality filters will eventually burn out due to the heat emitted by UV light, ultimately rendering the light useless and requiring replacement.) What makes minerals fluorescent?Ultraviolet light is a form of electromagnetic radiation. Fluorescence occurs when electrons in certain atoms of a crystallized mineral absorb the radiated energy from a UV light (Photons). The incoming photons bump the electrons into higher energy states, and they respond to the ultraviolet light. The remaining light energy is out of balance and remitted and can be seen as a visible color. The reason for the fluorescent remitted colors is due to impurities in the mineral, or activators; which become part of the mineral’s chemistry by taking the place of atoms in the host mineral.
A majority of activators are atoms of certain metal elements that cause the resulting fluorescence in a mineral, Manganese being the most common activator. The level of fluorescence depends on the percentage of the impurities in relationship to the host atoms. Too much/little, results in low or no fluorescent response.Thanks for looking!
