    Native Copper in Calcite
    Tamarack Mine, Tamarack, Calumet Township, Houghton Co., Michigan, USA

    For those who like superb mineral specimens with an extra dose of history, we have an enormous, outstanding, Calcite crystal, sitting on, and included by, dendritic growths of Native Copper. The specimen is from the collection of Capt. John Daniell, who opened the Tamarack Mine in 1882. The mine produced 389,215,899 pounds of Copper in 35 years: that's 194 THOUSAND TONS of Copper! This is not shabby at all for the district. His collection was sold to Ward's Natural Science Establishment around 1950, who then sold the piece to Robert Hesse, where it was entered it into his collection records in July of 1950, as number 232 (on bottom). Upon Hesse's death, his collection went to Richard Hauck, who in turn sold it to Ed David: President Nixon's Science Advisor (accession # 65T on bottom). The crystal next was traded to Phil Scalisi. Phil kept the piece for 15 years or so, before the specimen crossed the Atlantic to French collector Eric Asselborn. Recrossing the Atlantic, the other direction, it went to Rob Lavinsky, and from him, on to Robert Nowakowski. Quite a piece of history for one specimen! The specimen is composed of a very large, single Calcite crystal of a pale pink hue and excellent transparency. Native Copper growths form the matrix and creep up one of the faces of the crystal. Inside the crystal, one can see shining growths of Native Copper rising up from the base of the crystal. The Calcite is twinned and it shows a number of "rainbows" caused by that twinning. Under SW-UV, the Calcite shows weak red fluorescence with some very weird cream yellow-green fluorescing inclusions, one of which is worm-like in its twisting form: very strange. The condition of this stellar example of Native Copper in Calcite is pristine. It will be a long time before one this large, or this aesthetic, is offered again.
