Cobaltoan dolomite from Democratic Republic of Congo formerly Zaire. This eye-catching natural mineral is well known for its distinctive pink coloured crystals and although not particularly rare, it can only be found in a small number of locations worldwide.
Despite not having been able to find out too much about cobaltoan dolomite, we know that it's very similar to the mineral calcite but have not been able to establish conclusively whether it's the same stone as coboltoan calcite. Some of the pieces that we have bought from suppliers in Africa are labelled as cobaltoan dolomite whilst others are labelled as cobaltoan calcite.
