Melonite
Melonite after calaverite, on quartz. Cresson mine, Cripple Creek, Colorado. Size: 1.3 x 0.9 x 0.4 cm.General Category Sulfide minerals Chemical formula NiTe2 Strunz classification 02.EA.20 Dana classification 02.12.14.01 Unit cell a = 3.84 Å, c = 5.26 Å Identification Molar mass 313.89 g Color White, reddish white Crystal habit Crystalline, foliated, granular Crystal system Trigonal Cleavage {0001} Perfect Fracture Brittle Mohs scale hardness 1-1.5 Luster Metallic Streak Dark gray Diaphaneity Opaque Specific gravity 7.72 Density 7.3 Ultraviolet fluorescence None References [1][2][3] Melonite is a telluride of nickel; it is a metallic mineral. Its chemical formula is NiTe2. It is opaque and white to reddish-white in color, oxidizing in air to a brown tarnish.
It was first described from the Melones and Stanislaus mine in Calaveras County, California in 1866, by Frederick Augustus Genth.
