Rhodonite is pretty rare in most areas of Cornwall the exception is a wide circle of mines around Launceston where it occurs readily within manganese deposits. The photos show two such specimens the first and darker one also contains Bustamite and Tephroite showing as the brown infill. Both specimens have been cut and polished from much larger blocks.


A rarity for Herodsfoot although some magnificent calcite specimens were collected underground in the 1800’s its occurrence on the dumps is rare.

This specimen is made up of cubic pyrite, bournonite, siderite, paper calcite, galena and quartz.
