A rich Develline in the classic Lavrion specimen combination with Gypsum from the Jean Baptiste Mine, Greece. Gorgeous blue green botryoidal crystalline Develline is seen to admirably cover the display face of the specimen. Other areas are also liberally aggregated and scattered with crystals of Develline. Associated minerals are gemmy colourless crystals of Gypsum, and a white covering of probable Gibbsite, on a light brown Calcite matrix. A rich specimen from the mine.
