Silver-Copper "half-breed" with Prehnite

Item Description

A very rich, showy, old-time silver-copper "half-breed" from the famous mines of Michigans 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 barite. Ex Mullane Collection. Hefty at 91 grams for the size. Rich silver ore here.
