Phlogopite Twinned Crystal.  Selleck Road, St. Lawrence County, New York.  These are extremely rare examples of triplet twins which present themselves in a "Mercedes Benz" like form.  This example measures 2.8 x 2.4 x 2 cm and shows all of the three flanges beautifully.  It looks like there may be some flaking of the upper layers but this is difficult to tell, for sure. The backside also shows nice twin features $130
