Two choice double terminated greyish-white crystals of Witherite are perched on a bed of small Alstonite crystals, from the alstonite joint type locality of Fallowfield mine at Acomb near Hexham in Northumberland. The smaller Witherite crystal measures 22 mm tip to tip; the larger crystal 33 mm, although the lower half of the double termination is not complete due to contact with the matrix. The semi-matt lustre of the Witherite crystals suggests they are coated with a very thin film of Baryte. All the Alstonite crystals are to about 2 mm across and are perfectly terminated. The matrix underside of the specimen consists of intergrown platy colourless Baryte. A super example of these two rare British barium carbonate minerals.
