La melonita és un mineral de la classe dels sulfurs. Va ser descrita per primera vegada l'any 1866 per Frederick Augustus Genth a partir de mostres obtingudes de les mines Melones i Stanislaus; rep el seu nom del primer d'aquests indrets. (ca) Melonit ist ein relativ selten vorkommendes Mineral aus der Mineralklasse der „Sulfide und Sulfosalze“ mit der chemischen Zusammensetzung NiTe2 Melonit ist damit chemisch gesehen ein Nickeltellurid, genauer . Als enge Verwandte der Sulfide werden die Telluride in dieselbe Klasse eingeordnet. Melonit ist das Nickel-Analogon zu Shuangfengit (IrTe2) und kristallisiert wie dieser im trigonalen Kristallsystem und entwickelt hexagonale Täfelchen bis etwa einen Zentimeter Durchmesser, findet sich aber auch in Form kleiner, lamellarer Partikel. Das in jeder Form undurchsichtige (opake) Mineral zeigt auf den Oberflächen der rötlichweißen, auf polierten Flächen auch weiß bis schwach rosa erscheinenden Kristalle einen metallischen Glanz. Mit der Zeit läuft Melonit gelblichbraun an. (de) Melonita sulfuro motako minerala da. (eu) 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. Melonite occurs as trigonal crystals, which cleave in a (0001) direction. It has a specific gravity of 7.72 and a hardness of 1–1.5 (very soft).
