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 3.2 x 3 x 1.4 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.  $95
