Fine clusters of dark blue-green drusy botryoidal areas of Develline measuring to 2.5cm from the 'pania Dolina area in Slovakia. Once called Herrengrundite from this old European mining area, the botryoidal forms are composed of tightly packed lath-like crystals, some partly coated by light pastel blue Chrysocolla, on a light sandstone matrix. An excellent Develline specimen from the area.
