An old-time, showy, representative Bisbee specimen of a turquoise-blue mineral formerly known as bisbeeite (now known to be chrysocolla) with darker blue smears of shattuckite; and accented with two, small vugs lined with malachite. Shattuckite is a rare copper silicate and this piece is from the Type Locality - the Shattuck Mine. Old material, as this mine closed in 1947. Ex. Mullane Collection.
