| 28302: Hemimorphite, Gypsum and Willemite
- $24 Hidden Treasure Mine, Jacob City, Ophir Mining District, Tooele County, Utah Miniature - 5.7 x 4.6 x 3.5 cm 80 grams Specimen status: Reserved Send an email with specimen number to order Somewhat sparkly, gray
microcrystalline hemimorphite covers the specimen's
display face. A portion of the hemimorphite carpet is
covered with a rug (? what covers a carpet?) of colorless
gypsum. Interesting association for the locality. Some
spots on the matrix just below the hemimorphite layer
display a bright blue fluorescence under shortwave UV,
suggesting the possible presence of willemite (but this
species is not listed at Mindat for the
locality). Self standing and in superb condition.
