This “stone” is actually paint from the Corvette factory in Kentucky. The colours are brilliant and the formation within the stone is one of a kind. This pendant looks great on a sterling silver chain and a black leather necklace, so both are included for a variety of looks. The pendant, including bail, measures 2.75 inches long. The silver chain is adjustable up to 18 inches and the black leather necklace is adjustable from 18-20 inches. Complimentary polishing cloth included.
