Item Description

Beautiful royal-blue plancheite botryoids are richly complemented by contrasting crusts of chatoyant nubby botryoidal velvet malachite on this colorful and sculptural large specimen from recent finds at the famous Milpillas Mine. Plancheite, a rare hydrated Cu-silicate, is an uncommon accessory species from the well-known locale. The piece displays well without aid. See the excellent and extensive 2021 Mineralogical Record Mexico Special Issue IX, Vol. 52, No. 5 for more details. Ex Vasco Trancoso Collection and illustrated in the MINDAT Photo Gallery for the species and locale. Striking color contrast on this rich combination specimen.
