Chalcopyrite (ex Willard Wulff Collection)

Item Description

The Eagle mine is probably best known for its sulfide specimens. This cluster is a great display piece of Eagle mine Chalcopyrite showing classic sharp, lustrous faces. The largest crystal measurs 2.0 cm across, which are coated by Sphalerite, and the piece is in good shape overall. A nice representative miniature piece of this well known material from this now defunct locality. This specimen 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. You can read Willard's bio on the Mineralogical Record website here ( http://www.minrec.org/labels.asp?colid=1528 ). The piece comes with a typed label from Wulff on one of his famous 3x5 index cards.
