Amphibole Bear Lake diggings, Maddill Road, Tory Hill, Ontario, Canada. In the early 1990s I found and mined a large amphibole pocket that produced a handful of these long, prismatic crystals along with many of the stocky, more traditionally shaped crystals. Then they were referred to as fluor-magnesio-kataphorate. Now, likely classified as fluoro-kataphorite but they should be analyzed to determine the species. This one is a lustrous, black specimen with two terminations. This is a twinned crystal with the twin plane being obvious on the termination view. This is also seen in several other crystals form this discovery. The piece is a single crystal that measures 7.9 x 3 x 1.5 cm. The backside of termination has a chunk missing. $75
