Connellite is a very rare hydrous copper chloro-sulphate and occurs in several locations around Cornwall. This small miniature is from the famous Wheal Unity, part of the St. Day U nited mines in the parish of Gwennap, east of Redruth and is small, but exceptionally rich. The Connellite occurs as compact dendritic growths surrounded by massive green Malachite but rising up from finely crystallized deep purple-red Cuprite. The Connellite is mostly almost jet-black but with flashes of its classic intense royal-blue colour. The tips of the 'dendrites' are terminated with glossy, black, sharp pyramidal crystals which are believed to be Connellite in an exceptional state of crystallization. This undoubtedly very old specimens comes with an old Julius Bohm (Vienna) handwritten label (address dated to 1890-1910) specifically documenting it as from Wheal Unity. An unassuming classic Cornish rarity from Professor Werner Paar's collection. Show more
