From the deposit that arguably produced America's finest ferroaxinite, this glassy and gemmy quartz specimen is highlighted by the vertical thread faden and by small amounts of epidote which impart a slightly green hue to the quartz. We've never seen another from this deposit. For that matter, we can't recall seeing a Faden Quartz from any US locality other than Arkansas.
