Sphalerite with Pyrite (ex Willard Wulff Collection)

Item Description

A lovely specimen of Sphalerite with Pyrite from the Idarado mine. The jet black Sphalerite crystals measure up to about 2 mm and show fine, sharp, lustrous faces which are set against the shimmering golden metallic Pyrite in a beautiful cluster. Minor Calcite can be seen on the piece as well. A great toenail display specimen of this hard to find material from this classic locality. This piece comes from the collection of Willard W. Wulff (1904-1998) of Colorado Springs, Colorado, a prominent figure and collector of Colorado minerals. Wulff was one of the founding members of the Colorado Springs Mineralogical Society in 1936.
