Tourmaline (Dravite with Fluoruvite core) on Phlogopite Powers Farm, Pierrepont, St. Lawrence County, New York. Field collected by Michael Walter Summer 2013 from classic site on hilltop. These specimens collected during the 2013 season are fine examples naturally weathered from a large open vein that was somehow missed by many decades of serious collectors that came before me. I spent 38 days working the vein to recover these specimens which are all of very fine quality. Again, these specimens are naturally exposed, not etched, so they are exceptionally stable and the tiny fractures seen in close up views are almost always fully healed. Most came from a depth of five to ten feet below the surface and many could benefit from further cleaning. This is a top quality specimen and not the cheap stuff one finds on e-Bay that gets etched from massive calcite in someone's back yard. The base of this specimen is a single, large complex, step growth mica crystal with smaller attached micas and tourmaline. Somewhat fragile specimen but attractive and interesting. The specimen measures 6 x 4 x 2.7 cm overall. $90
