Clark & Coombs began in 1872 as a burnisher and finisher for a large silverware manufacturer in North Attleboro, Mass. In 1875 they began manufacturing rings and relocated to Providence, Rhode Island.

Hematite comes from the Greek word for blood. It has been used as an amulet against bleeding, and so is known as the "blood stone". When arranged like the petals of a flower, it is referred to as the "iron rose". Native American folklore states that war paint made from hematite will make one invincible in battle. People in the eighteenth and nineteenth centuries wore hematite jewelry during mourning. Brazil is the most important source of hematite. Other sources include: China, Canada, England, and Germany.

This lovely ring, circa 1930-1940, has an oval, faceted Hematite stone prong-set in a delicately chased sterling silver mounting, size 7. The ring is stamped stamped "Sterling" and the manufacturer logo "C & C". Good vintage condition with some light scratches on stone, seen under magnification, and original patina.
