Various U.S.locations
    Although each of these three specimens is from a locality in the continental United States, they are often referred to as "foreign" fluorescents because to collectors of fluorescent minerals, the field is usually considered to consist of Franklin, New Jersey versus the rest of the world, including the rest of the US. That is to cast no aspersions on the standard of these specimens, however, each of which is of first-class quality. The bulbous, gently tan-colored specimen, 4½ x 3¼ x 2 inches (11.4 x 8.3 x 5.1 cm), is Halite, or Rock Salt, from the Salton Sea area of California, which under shortwave ultraviolet light fluoresces a brilliant orange, due to a small percentage of Manganese and an even smaller percentage of Lead. The lovely snowy-white specimen is not in fact a true crystal, but the closest thing to it in a fluorescent Chalcedony specimen known as "Chalcedony Rose". Measuring 4¼ x 3 x 2 inches (10.8 x 7.6 x 5.1 cm), it hails from Grant County, New Mexico and bursts into vivid life under shortwave ultraviolet, glowing with an exceptionally bright green color. The third specimen consists of a druzy fluorescent coating of Scheelite crystals in rare combination with Calcite crystals, from the Ophir Hill Mine in Tooele County, Utah. The patch of Calcite fluoresces with its characteristic fiery orange-red under shortwave ultraviolet light, whilst the carpet of yellowish Scheelite crystals turns a brilliant blue-white, indicating that they are nearly pure Calcium Tungstate (the blue tint is a sign of purity). It measures 3 x 3 x 2 inches (7.6 x 7.6 x 5.1 cm), with the Scheelite forming a triangle 3 x 3 x 1½ inches (7.6 x 7.6 x 3.8 cm) on one end. Offered at no reserve.

    Provenance: ex. Hugh Ronemus Collection.
