An apple-green variety of chalcedony, colored by nickel. It has a dull flinty luster, and is sometimes used in jewelry.
This member of the chalcedony family is often referred to as â€œAustralian Imperial Jadeâ€ because of its vibrant green color. In the 1800s it was used by thieves who thought it made them invisible. In modern times, it is worn to encourage fidelity and even cure a broken heart. Chrysoprase is an alternate birthstone for the month of May.
Translucent green with a bluish tint.
