Here's an intriguing specimen featuring 2 HERKIMER DIAMOND QUARTZ crystals in CALCITE from Treasure Mountain Diamond Mine in Little Falls, Herkimer County, NY. The mine has been closed since the end of the 2001 season, and is now owned by a farmer who does not tolerate trespassing collectors. The Herkimer Diamonds (also known as Little Falls Diamonds) are very sharply terminated. The amazing thing about the herkimer diamond crystals (actually quartz) is that they are embedded in a sharp calcite crystal cluster - a rare occurence. This unusual specimen was collected by the noted New Hampshire mineral collector, Frank J. Murphy in 2001, and it comes with his original label.
