Specimen of the mineral pseudomalachite (BIRUG 522). Pseudomalachite could easily be mistaken for actual malachite; however, whereas malachite is copper carbonate hydroxide, pseudomalachite is copper phosphate with hydroxyl. Similarly to malachite (and demonstrated in this specimen) it is often found with a botryoidal structure (from the Greek “botrys” meaning “the grape”).
This specimen was collected from Nizhny Tagil, Russia; the original label has a note from Dr. Percy, “from Nordenskiold 1851”, alongside Nordenskiöld’s writing, indicating that the specimen was collected by Adolf Erik Nordenskiöld in 1851. The specimen was gifted to the Lapworth in 1915 by W. McLean and forms part of the Museum’s McLean collection. Scanning was performed using an Artec Spider 3D scanner by Courtney Szanto.
