Colour:White
A variety of Smithsonite

NOTE: The yellow Turkey Fat Ore style Smithsonites previously described as "Cadmian Smithsonite" are actually a mixture - they are Smithsonite with inclusions of Greenockite.
This variety was first described from Segen Gottes Mine, Wiesloch, Heidelberg, Baden-Württemberg, Germany.

True CdCO3, or Otavite, is naturally white, so cannot colour Smithsonite yellow. True Cadmian Smithsonites should therefore be white.
