Plancheite and Malachite (rare for locale)

Item Description

Dramatically colorful, rich, impressive and rare large combination plate from recent finds at the now famed Milpillas Mine, notable for diverse copper species but from which Plancheite is super rare! Here is a big display size plate: Rich sky-blue Plancheite botryoids, a hydrous copper silicate, considered rare from Milpillas are strikingly contrasted by rich green, dramatically chatoyant, spherical clusters of fibrous Primary Malachite. Ex John Dagenais Collection, a well-known Canadian collector. See the fine 2021 Milpillas Mineralogical Record article in Mexico Special Issue - IX, Vol. 52, No. 5. Specimens of this size, richness and combination quality are rare and seldom on the market from here. This specimen is illustrated in the Mineralogical Record, Northwest Collectors issue showing part of John's collection, page 51 (2019).
