You are bidding on a outstanding specimen of Schroeckingerite in gypsum clay from the Red Desert, Sweetwater County, Wyoming. Schroeckingerite is a Hydrated Sodium Calcium Uranyl Sulfate Carbonate Fluoride. It got it's name from Julius Freiherr Schrockinger von Neudenberg(1814-1882), Austrian geologist, who discovered Uranium at Jochymov, Bohemia, Czech Republic. It is one of the most brilliant fluorescent minerals and is equally bright using either shortwave or longwave UV lamps. Many people see the color as yellow-green, my eyes see it as blue-green. It is also fluorescent yellow colored in normal light. When I took the photo, I had to hold the lamp two feet away. When it was close to the light, it was so bright that my camera just showed a bright blur. If you plan on putting this into a display cabinet, you will need to put it in a bottom corner as far away from the lamp as possible to keep it from overwhelming your other fluorescents. It is a relatively rare mineral. It forms as round pellets in a gypsum clay. Elsew, it occurs as a thin coating on other rocks. This mineral was once known as Dakeite named in honor of the famous mineralogist, H.C. Dake. It was later found to be schroeckingerite and the name dakeite was dropped. Do not get this specimen wet as the schroeckingerite will dissolve in water. Avoid excessive handling as the gypsum clay is crumbly. It measures 1 3/8 x 2 x 1 1/8 inches and weighs 1.3 ounces. This will make a great addition to your collection. Shipping to US addresses will be $1.85.
