Witherite

Witherite, a relatively rare barium carbonate, crystallises in the orthorhombic system and forms pseudo-hexagonal prisms of variable geometry at Nentsberry Haggs mine on Alston Moor in Cumbria.  In this incredible specimen, the prisms are completely flattened to form hexagonal crystalline plates of around 3 cm on edge, about 5.5 cm across flats and 5 to 8 mm thick.  Of translucent pale straw-yellow, these plates are stacked forming a large pagoda-like stepped tower emanating from a mixed Witherite and grey granular matrix.  A magnificent and heavy cabinet display specimen.  Please note: an additional postage charge may be applicable due to this specimen’s weight.
