Rockport, Essex Co., Massachusetts, USA 6.8 x 5.4 x 4.6 cm. According to MINDAT this is a very rare member of the Mica Group in the Biotite-Phlogopite Series. Regardless, it’s the most oddly crystallized mica I have seen. It looks more like a dark phosphate than a mica. From the TYPE LOCALITY where it was first noted in 1868. Ex. Academy of Natural Sciences Philadelphia Collection. |
