A high-quality sample of the newly described rare mineral from the pumpellyite group, julgoldite-Fe^2+, which forms fan-shaped aggregates about 2 mm in size composed of fibrous dark green crystals. These aggregates grow into the cavity along with the crystals of light yellow-green datolite. A very nice specimen of this mineral species, originating from the Košťálov quarry.
