Item Description

Here we have a fine example of an aesthetic, bright Copper specimen from one of the most historic and classic mining districts in the United States. This piece features beautiful, fairly well-defined, "Spinel-Law" twinned crystals, which comprised modified and skeletal dodecahedra of Copper which are flaring in every direction. The crystals are relatively sharp and bright, and the piece can easily be displayed from several angles. These specimens are becoming more and more difficult to find on the market today, and this is a very nice display specimen of this most highly sought after material from Michigan.
