Zircon
Zircon is one of the earliest created stones, having originated at the same time as Earth. Zircon is a mineral that occurs in a range of hues, but its name derives from the Persian word zargun, which means gold-colored. It has long been popular and well-known. Zircon gemstones were thought to be able to promote restful sleep, fend off evil, and bring wealth and knowledge throughout the Middle Ages.
