Item number: 20023

This specimen is mostly composed of grey-metallic skutterudite, along with some nickeline in the bottom. There is also some carbonate which has been partly removed to reveal, sharp cube-octahedral of skutterudite. Where the aggregates are broken at the sides of the specimen, it appears that the skutterudite formed on nickeline. Of course, with these minerals, the specimen is dense! Very interesting specimen from an unusual location! t
