Item Description

A classic old-timer from the lesser known Mojina Mine in Chihuahua. Beautiful blue Celestien and white Calcite are intergrown to form somewhat "stubby" finger-like protrusions flaring out of the underlying matrix. The piece is in good shape on the display side, though obviously it's not perfect along the periphery where it was removed from the pocket wall. Interestingly I'm told that the green fluorescence is actually caused from a minor coating of Hyalite Opal (Opal-(AN)). Hard to find on the market, and certainly worth picking up if you collect carbonates or Mexican minerals. 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 that states the piece was acquired from Bob Criss.
