192G YGX Purple Fluorite Quartz Wulfenite Fluorescent Combo Crystal Specimen 306

Description: YGX Purple Window Fluorite Clear Quartz Chlorite 192 Gram Combination Fluorescent Crystal Mineral Specimen Yaogangxian Mine Hunan Province Locality: Yaogangxian Mine Hunan Province, China Weight: approx. 192.67 Grams Measures: 3.06'' (77.86mm) x 3.52'' (89.60mm) x 2.75'' (69.70mm) This stunning combination specimen from the Yaogangxian Mine in China is full of contrasting minerals with various sizes of Clear Quartz crystals points at every viewable angle, Purple Window transparent Fluorite cubes along with an etched Purple Fluorite crystal coating, a Green Chlorite coating, some Pyrite and even a little Black Tourmaline just to name the obvious minerals! Clearly this piece has a great aesthetically pleasing colorful composition at first glance! But when taking a closer look, you'll find it's not only loaded with tiny Quartz points and Fluorite cubes, but there are also tiny yellow to orange Wulfenite crystal growth seen through a 30X jewelers loupe, around the base of this piece. This combo specimen really shines under LW UV light as it fluoresces a brilliant electric blue, and as seen in the pics, you can see the blue fluorescence reflection on the Quartz points. It's apparent viewing this specimen from various vantage points that there is an endless landscape of mineral discovery within every valley and cavern! 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 FE90mm Macro G Lens and 3 - LWUV 365nm flashlights with included ZWB2 black filter glass. 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 and the correct wavelength for the specific mineral you wish to fluoresce and it needs to have a high quality filter ( ZWB2 or Hoya black filter glass) to allow the transmission of pure UV light through the filter while restricting natural light to result in a response. A dark room is also necessary for the best UV reaction. (LWUV 365nm Long Wave Ultra Violet Light or UVA, MWUV 310nm or UVB, & SWUV 255nm or UVC) ***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. Fluorite, is also known as Fluorspar, and is named for its fluorescence under ultraviolet (LW UV 365nm) and cathode-ray irradiation. Since pure Fluorite is colorless, the existence and specific levels of these impurities determine the color of Fluorite in natural light, but also lead to the fluorescent color and phosphorescence it remits.
