An aesthetic specimen of white to yellowish datolite with needles up to 12 mm on the edge of the vein bordered by small datolite crystals. Part of the specimen in its edge contains a rare mineral newly described in the Czech Republic from the pumpellyite series, julgoldit-Fe^2+. It forms fan-shaped aggregates up to 5 mm in size, composed of fibrous dark green crystals in association with pyrite and the newly described datolite from the locality. This mineral species is a very nice example, originating from a quarry in Košťálov.
