This outstanding full miniature specimen has all the qualities you could ask fo rin a historic copper in calcite: good luster, clarity to the calcite, rich inclusions, and good aesthetics. However, more than that, it has also free vein copper and a crystal of copper in association, which is uncommon. This is most certainly an old specimen, and many came out prior to the early 1900s. For the size, and beauty, I regard it highly. They are seldom available today, and remain almost unique to Michigan's historic copper district
