Gahnite, Quartz
Davis Pyrite Mine, Rowe, Franklin County, Massachusetts, USA
Lots of deep blue-green gahnite crystals in milky quartz from this old-school New England locality. Many of the crystals are broken, but a significant number, especially among the larger ones, show good faces with interesting striations. Acquired at the Jackson MI show from Dan & Shelley Lambert; ex Ted C. Johnson collection, East Hampton CT.
