BARYTOCALCITE

Well-formed, 'sharks-fin' off-white coloured blades of Barytocalcite (the largest to 2.1 cm in length) form fan-like aggregates to 3.9 cm across, sitting proudly on a marly limesto ne matrix coated in small grey rhombohedral Calcite crystals. This habit of Barytocalcite is unique to Nentsberry Haggs mine near Nenthead in Alston Moor, Cumbria and most specimens like this came from the Admiralty Concession flats which required a considerable effort to get too. There is some damage to the tips of a few of the crystals, where their darker fudge-coloured interior shows through, but this does not detract from the overall size and impression that this fine English rarity gives. A north of England classic and not forgetting how rare Barytocalcite is as a species worldwide. Show more
