Is chrysophrase a igneous sedimentary or metamorphic?

Chrysoprase is a variety of chalcedony, which is a form of silica. It is primarily considered a sedimentary mineral because it forms from the deposition of silica in sedimentary environments, often in the presence of nickel, which gives it its distinctive green color. While it can be found in some metamorphic settings, its formation is most commonly associated with sedimentary processes.
