Amphibole    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 a multiple terminations. Many would consider this to be several crystals in parallel growth but it is actually a twinned crystal with the twin plane being obvious on one side of the piece running the length of the "C" axis. This is best seen in the third image and more evident in several other crystals form this discovery. The piece is a single crystal that measures 10 x 3 x 2 cm. There is no damage.
