Pyrite (ex Brian Kosnar Collection)

Item Description

The Eagle mine is probably best known for its pyritohedral Pyrite specimens. This cluster is a great dipslay specimen of Eagle Mine Pyrite showing typical striated pyritohedra with sharp faces which are associated with rarely seen dark Sphalerite crystals up to 1.3 in the center of the specimen. At one point there were hundreds if not thousands of these specimens available, and they are now seldom seen for sale like most classic minerals from Colorado. The largest Pyrite crystal measures 1.1 cm across, and would make a great addition to any Colorado mineral suite.
