Smithsonite

This smithsonite formed in the oxidized zone of a zinc-rich deposit, where mineral-bearing waters replaced earlier ores and deposited smooth, often botryoidal masses of zinc carbonate. The Kelly Mine is a classic American locality, famed for its richly colored smithsonite in shades of blue, green, and pink.

Softly lustrous and vividly colored, this specimen reflects the unique conditions that make the Kelly Mine one of the most celebrated sources of smithsonite in the United States.
