Smithsonite

Smithsonite
Zinc Carbonate, ZnCO3

Smithsonite is a secondary mineral commonly found in the oxidized zone of zinc deposits in limestone gangue. It is formed by the alteration of sphalerite and is commonly associated with hemimorphite, cerussite, malachite, azurite, anglesite and other oxidized lead and zinc deposits.

David Michaels provided this comment:
"The Smithsonite was purchased from Amethyst Galleries ---my first ever purchase of a mineral by mail order or -cyber-order. This rock is the example used by Amethyst in their Smithsonite section. I think this color is more true."
