Faden Quartz
Toenail, 3.1 x 2.7 x 2.0 cm
New Melones Spillway, Calaveras Co., California
Ex. Carl Acosta
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.
