Babingtonite from West Springfield, Hampden Co., Massachusetts, United States

Clusters of quite large striated lustrous black Babingtonite to 2cm that appear to be etched out of a layer of course white Calcite on matrix. These are huge crystals for the species and virtually free of damage. Excellent specimen for the Mass. collector!!
