CHRYSOPRASE



NOUN

  1. an apple-green gemstone consisting of a variety of chalcedony that contains nickel.

    • (in the New Testament) a golden-green precious stone, perhaps a variety of beryl.



ORIGIN Middle English (denoting a precious stone in the New Testament): from Old Frenchcrisopace, via Latin from Greekkhrusoprasos, from khrusos‘gold’ + prason‘leek’.



Chrysoprase is a form of silica, much like sand or quartz, but it is made distinctive by the deposits of nickel in the stone that give it a distinctive green colour. This is different from emerald, the other most famous green stone, which gets its colour from chromium deposits.
