Covellite with Pyrite Calabona Mine, Alghero, Sassari Province, Sardinia, Italy 5.85cm x 3.17cm x 2.35cm Ex. Ex. Thomas J. Campbell Collection #S-09

Description/Interesting Notes: A classic, old time example of covellite from this historic locale!!! This specimen consists of a handsome grouping of densely intergrown covellite crystals in association with numerous golden pyrite crystals!!! The covellite crystals are unusually thick and have gorgeous, bright, iridescent blue and purple metallic luster!!! The hexagonal form of the crystals can clearly be seen in numerous areas and there are several complete crystals present as well!!! The pyrite crystals are present as unusually compressed crystals scattered across the faces of the covellite crystals - a characteristic feature of the locality!!! This specimen came from the collection of Thomas J. Campbell, co-author of Encyclopedia of Minerals!!! Classic old time material!!! The pics hardly do it justice!!!
