St. Lawrence County, New York, Specimens for Sale


                        Diopside                                                              Diopside in Tremolote


This location is a long closed, historic east coast locality.  It is perhaps the most famous New York locality for gem material, diopsides, however it has been a long time since this location has produced material.  It is under private ownership and being worked for mineral specimens at this time.  This being said, very few are being produced and they remain one of the "holy grails" of East Coast mineral collectors.
