A rare and collectible specimen of cleiophane in association with galena and quartz, from the well-known Bulgarian Krushev Dol mine, located in the Madan region – one of the most important sulphide locations in Europe. Cleiophane is a rare, zinc variety of sphalerite, occurring in this sample as a translucent, light yellow to greenish cluster with a glassy luster. The mineral contrasts with the massive, silvery galena and finely crystalline, transparent quartz, giving an interesting visual and textural effect. Such combinations from Krushev Dol are difficult to find in this quality and look great in collections of European ore minerals. The specimen is in very good condition, without damage.
