Here we have an excellent specimen with multifaced and highly metallic Bournonite accompanied by bladed creamy Baryte and disc-shaped, pale beige Siderite. Bournonite is a highly sought-after sulfosalt originally found in Cornwall. These splendent, mirror bright metallic-gray Bournonite crystals have a luster which blasts you away. The major cluster is perfectly set atop the specimen. So contrastful, well balanced and aesthetics, really unusual for a Peruvian Bournonite. Appraised in our stock with € 500,00. So far I can see, the Bournos are pristine.
