Hi Gini,

    I sometimes facet Danburite for my collector customers. Right now
    the pale yellow variety from Madagascar seems to be in demand.
    Usually, the more common color is colorless, and from Mexico or
    toher locations. The hardness is around 7, the same as amethyst or
    citrine, but the Refractive Index is about 1.63, so it cuts a
    brighter stone than quartz. In fact, Danburite is known for its
    exceptional transparency (or "water" as Riched Hughes calls it) and
    cuys a very, very pretty stone when the angles are correct for the
    design and the polish is well done with facets very flat. I like it,
    it's very different....but I have never seen any with a green tinge. 

    I don't know the "value" or that there is a real established value,
    but I can tell you that I get around $35-40/c for stones I cut
    (fancy shapes) in the 7-12 carat range. Standard cuts like round,
    plain emerald cut, etc., are less...it's really a matter of time
    spent at the wheel for high precision, as the rough is inexpensive.
    Hope that helps, enjoy your pretties!!
