Thumbnail, 2.3 x 2.2 x 1.7 cm
Franklin, Franklin Mining District, Sussex Co., New Jersey, USA
This is an outstanding single crystal, on matrix, that is complete all around. The very good luster and sharp crystal form make it surprisingly attractive for a black mineral. Considering that most Gahnites you see referenced are micros, you realize what a killer thumb this really is. And the classic, historic locality is a bonus, anyhow. 2.3 x 2.2 x 1.7 cm
