The name Chrysoprase is from Greek, Chrysos means "golden" and Prason means "apple" or "leek."

It is a form of chalcedony and it is sometimes translucent with colours ranging from apple green to deep green due to nickel oxidization. Though darker color is considered more desirable, once it reaches a certain depth, it will no longer be identified as chrysoprase, but rather as another variety of Chalcedony known as Prase.

The colour of chrysoprase may fade if it is exposed to prolonged heat and strong sunlight. So, make sure to keep your chrysoprase away from these harsh elements.
