Silver, Copper
Small Cabinet, 6.4 x 2.9 x 1.8 cm
Keweenaw Co., Michigan, USA

A very rich, showy, old-time silver-copper "half-breed" from the famous mines of Michigan's Copper Country. The sculptural specimen has an uncommon, particularly high silver content that I estimate at 70-80% or more. Most half-breeds have a silver content of less than 50%. The piece is nicely complimented by a small cluster of sea-green prehnite botryoids and embedded, layered, off-white analcime or baryte. Ex. Mullane Collection. Weighs 91 grams.
