The vast collection of minerals--smooth turquoise smithsonite
from New Mexico, spiky orange crocoite from Tasmania, dazzling purple amethyst from Uruguay, and large specimens of sulfur from Sicily--are recommended for a viewing at the Harvard Museum of Natural History.

The common secondary zinc minerals are smithsonite
Fe) S, and to a lesser extent smithsonite
(ZnO3), willemite (Zn2SiO4), and zincite (ZnO) (Reimann and deCaritat, 1998).

(Namibia), sphalerite (Spain), tourmaline (Maine, USA, and Afghanistan), tugtupite (Greenland), willemite/leucophoenicite (New Jersey, USA) and zincite on calcite (New Jersey); and also for 95 faceted mixed-shape tourmalines, mostly pink, green and blue.

Were it not for an unusual clause in his will bequeathing his entire fortune for the creation, in the United States of America, of a foundation to 'further the increase and diffusion of knowledge' then we would know him only for the mineral named in his honour, Smithsonite
, and for coining the term 'silicate'.
Which metal is obtained from calamine or smithsonite
6]} and smithsonite
(ZnCO3) which passivate the zinc surface; that is, these oxidized species protect the metal from further corrosion.
The tablets were mainly made of the zinc carbonates hydrozincite and smithsonite
, echoing the widespread use of zinc-based minerals in today's eye and skin medications.
