Excellent silver lead-grey dodecahedral crystals of the nickel-cobalt arsenide Nickelskutterudite richly cover a matrix of crystallised cream Dolomite and partly overgrown by greenish fawn micro-crystals of Siderite. This superb miniature is from the Schlema-Hartenstein Mining District in Erzgebirge, Saxony, Germany. The Nickelskutterudite form crystals averaging 9 mm in diameter although one more granular crystal attains 1.9 cm wide. A great specimen of this rare mineral from Saxony.
