Quartz
specimen number:
9771508
location:
Herkimer Co., New York, USA
description: Herkimer County, New York, is world-famous for its exceptionally clear, double-terminated quartz crystals known as Herkimer diamonds. These crystals formed approximately 500 million years ago within cavities of the exposed Little Falls Dolostone, a type of sedimentary rock, where silica-rich fluids slowly crystallized under pressure without touching a matrix. Modern mining and collecting history in the region dates back over a century, transforming local quarries and roadcuts into popular destinations for commercial miners, tourists, and mineral hobbyists searching for these natural treasures.
Glassy gemmy colorless crystals of quartz measuring to 1.5 cm in height coming nicely off matrix. This is in good condition.
