Tremolite (variety Chromium) and Talc     Washburn Farm, Macomb, St. Lawrence County, New York.  Collected by Michael Walter and David LaLonde, 2018.  There are two known chromium anomalies in northern New York that produce tremolite and neither is readily accessible.  This one on private lands produces the finest, large chrom tremolites in the east.  This is a fine thumbnail sized example and it measures in at 2.5 x 1.2 x .6 cm.  It is singly-terminated and as can be seen that termination is very complex.  The tremolite is a bright chrome induced green and very translucent.  These specimens are etched from massive calcite so almost always free of any damage however terminations on some of the tiny riders are chipped.  Minor talc coatings.  A nice example.  $30
