Missouri’s Official State Rock — Mozarkite


Found only in Missouri, the colorful Mozarkite is a special variety of chert, typically red, pink, and purple with varying tints of green or gray. It has won acceptance as a distinctive variety by lapidaries nationwide because of its unique varied colors. The rock’s beauty is enhanced by cutting and polishing for jewelry and is often considered a semi-precious gemstone.  Designated as Missouri’s official state rock in 1967, it is only found in the Show-Me State. The most abundant deposits are found in west-central Missouri, south of the Missouri River.  The Benton County town of Lincoln may have the only rock club dedicated to the stone. The Mozarkite Society of Lincoln promotes awareness and education about Mozarkite and the interest in the study of mineralogy, lapidary, and jewelry.  –Joe
