A striking polished slice of rich brick-red jasper displaying fine, parallel bands of dark charcoal gray and black.

Binghamite is a historic trade name associated with chatoyant quartz material from Minnesota's Cuyuna Iron Range, particularly around Crosby. It is often associated with iron oxides that produce reddish-brown, golden, and dark fibrous patterns. The Crosby area is known for its iron deposits and distinctive silica-rich lapidary materials, making this vintage-labeled specimen an interesting piece of Minnesota mineral history.
