Bismuth is a crystalline, brittle metal which resists being magnetized and is repelled by a magnetic field. 
It also has an unusually high electrical resistance for a metal.
Its thermal conductivity is lower than any metal except mercury and it has the unusual property that, like water, it expands as it freezes.
Bismuth relieves feelings of loneliness or isolation, it is a stone of transformation and change, helping to adapt to change with calm assurance.
