Chrysoprase is a green monocrystallized chalcedony whose name evokes its color: from the Greek “krhusos” meaning “gold” and “prasinos” meaning light green color “leek”. This natural stone owes its green / yellow color to nickel and more intense green to chrome. Chalcedony is often tinted by humans to achieve a more sustained and intense green to mimic natural stone.
