Description

You are bidding on a large and extremely rich sample of eucryptite with a large vug hosting hundreds of sharp, complex crystals of eucryptite on albite. There is a smaller vug that has a few of the sharpest, most transparent crystals I've ever seen from the locality. This is the richest and best sample of eucryptite I've offered to date from the mine and was collected by Peter Leavens in the 1960s. Bottom of the sample was sawn before inclusion into the University of Delaware mineral collection.
