Literally: golden leek

The story of the word

Gold plus leek: the Greeks named the stone for a leek green shot through with yellow. What actually produces the colour is nickel, which no ancient could have known and which is why the best material comes from weathered nickel deposits. Chrysoprase is another of the twelve stones listed in the foundations of the New Jerusalem, the passage through which a good half of the mineral vocabulary reached medieval English.
