Ex- means, literally translated from Latin, "out". It is often used as "previous" or "no longer" though. Ex-wife: Previous wife, no longer wife. A birthstone cannot become an ex-birthstone... That said, Bismuth isn't a birthstone (as far as I know). It's a pure element (that said too, I wonder why Diamond is a birthstone, it's a pure element too, carbon)
