MISSOURI STATE SYMBOLS   STATE LITHOLOGIC EMBLEM (STATE ROCK)   Mozarkite

 

Mozarkite was adopted as the official state rock for Missouri in 1967. Mozarkite appears in a variety of colors, predominantly red, pink or purple. When the rocks are tumbled and polished, they are sometimes used for ornamental jewelry.

The rock’s name is a combination of Missouri’s state abbreviation “MO,” “Ozark,” and the suffix “ite” meaning “of or pertaining to.” It is a chert (sedimentary rock) found exclusively in Benton County, Missouri, and the surrounding area. The rocks were formed approximately 450 million years ago.
