Pyrite with Hematite coating on Sphalerite matrix from Cavnic Mine, Cavnic, Maramureș County, Romania. Beautiful, lustrous pyrite crystals richly dusted with a fine hematite coating sit on a dark sphalerite matrix from the classic Cavnic Mine, Cavnic, Maramureș County, Romania. The hematite gives the pyrite a subtle, burnished sheen that contrasts elegantly with the metallic sphalerite below, creating a striking play of gold, red-brown and deep black tones. The Cavnic Mine is celebrated for producing world-class sulfide mineral combinations, and this piece exemplifies the locale’s quality with excellent crystal form and visual appeal. Such combinations of pyrite and chalcopyrite, occasionally with iridescent surfaces, are highly sought after by collectors for their vivid aesthetics and mineralogical significance. The Cavnic Mine in Maramureș County, Romania has not been operating since 2008, when all mines in the area were closed, the adits were sealed, and external infrastructure was demolished or is in the process of demolition.
