- Quartz (pseudocubic)
- Thumbnail, 3.1 x 1.6 x 1.0 cm
- Ace of Diamonds Mine, Herkimer Co., New York, USA
- Ex. Irv Brown
This is a very rare crystal habit from the famous mines in Herkimer Co., New York, showing the pseudocubic crystallization very dramatically, in a beautiful, water-clear, gem crystal. A stunning thumbnail of Quartz, worthy of standing alongside fancy species like Tourmaline and gem species in any advanced thumbnail collection. You just do not see quartz thumbnails so notable very often.
