RH6F8: This one is really for specialists. One of the crystals of Dravite from St Lawrence County. The specimen is, obviously, not that appealing as not all the faces have grown fully. But it is part of mineralogical history.
The specimen has been photographed and published in the magazine ‘Paragénesis’, number 01/2020, page 60
St. Lawrence County, New York  USA (±1980)
