It is difficult enough to find a good large crystal of Tsumeb dioptase. A pair of bisecting crystals is a real bonus. One of the holy grails of combo specimens is dioptase with wulfenite, so we added some. Then we dolloped a bit of planchiite to make this close to a one of a kind. ( wish we could dream up more!).
