This specimen is from the type locality for leightonite, which is an uncommon hydrated, potassium, calcium, copper, sulfate. The display side of the specimen is covered in intergrown sharp-edged, light teal colored crystals, to 3 mm in length. This is an unusually large and very rich specimen with gorgeous sea-blue color. This is old material, as well, seldom seen on the market. Al bought this in 2000 from a retired mine worker's collection.
