Excellent inter grown crystals of Sphalerite with Calcite and Dolomite from the Las Manforas Mine, Spain. Crystals of gemmy red-brown Sphalerite measuring to 2.2cm display a stunning play of orange-red fire, emanating from within the crystals when back lit. Snow white lustrous crystals of Dolomite have formed on the lower portion of the specimen with saddle shaped habit. A translucent creamy terminated crystal of Calcite has formed on the Dolomite crystals. A very pleasing specimen from the Mine.
