Exceptionnelle sphère de willemite, calcite et franklinite fluorescente sur socle

Large and Exceptional Fluorescent Willemite, Calcite and Franklinite Sphere on Stand
Sterling Hill Mine, Ogdensburg, New Jersey
Found only at the now closed zinc mines of Franklin, New Jersey. Polished into a sphere of very large diameter, the mineral appears speckled grey and brown in a white matrix by daylight. Under short-wave light the piece fluoresces a brilliant day-glow orangy-red and green. It also phosphoresces green. Created from fluorescent material mined at the famed Sterling Hill Mine, renowned for having the most vivid and the brightest fluorescent stones in the world. This sphere is one of only a very few spheres ever cut from this material and it certainly figures amongst the largest ever seen on the market. Fluorescing a bright neon green and bright red under shortwave UV light, this is an important collector's item not only for its vividness of color, but also for its size. Displayed on its metal stand, it is sure to form a novel conversation piece. Diameter 20.3 cm. Height 39.3 cm with the metal stand. (2)
