Description

    NATIVE SILVER with NATIVE COPPER
    Central Mine, Central, Keweenaw Co., Michigan, USA

    One would think that, when considering just how much Silver has been mined over the centuries, that more of it would have come from items like this arborescent group of Native Silver crystals, but not so. The metal Silver has such an affinity for other elements, Sulfur in particular, that hunks of metallic Silver are quite rare, much less crystals of this much sought after mineral. The result is that groups, such as this one from the Central Mine of Michigan's Upper Peninsula, are highly prized by collectors. Although the world market for Silver and other metals is quite strong and considering that the Copper and Silver ore bodies of the Keweenaw are not completely exhausted, it is still highly unlikely that pieces like this one will ever be produced there again. Along with the white metallic 'branches' of twinned Silver crystals, there is a smidgeon of Native Copper attached to one "branch," which unmistakably stamps the specimen as being a Michigan piece. This piece is in excellent to pristine condition with good differential patina. Originally from the W. Frank Ingram Collection; at some point in its' career it went through the hands of Ward's Natural Science Establishment whose label along with Ingrams' and Mr. Severances' accompany the piece. A catalog number (76.11) which corresponds to the Severance label, is affixed to one area of the specimen.
    Overall Measurements: 2.8 x 2.6 x 1 inches (7.1 x 6.6 x 2.6 cm)
    Offered at no reserve.

    Provenance: Ex. William Severance Collection, ex. Ward's Science Establishment Collection, ex. Frank Ingram Collection
