A very rich old-time specimen of Devilline from Špania Dolina in Slovakia. Dark blue green Devilline forms pseudohexagonal crystals, intergrown as rounded platy mounds to 1.5 cm long. All the separate patches total-up to about one quarter of the display face. Devilline is a calcium-copper sulphate. A terrific specimen from this old European mining area.
