This dramatic piece features a pristine, 3.4-cm-across fluorite with complicated, subtly layered, green-purple zoning. The crystal is pristine, complete, and totally translucent. The dolomite holding it up is very dramatic and 3-dimensional, complementing the fluorite by its very differrent shape and color. This is from a new pocket found at the end of 2008, and quietly trickled into Tucson in 2009. It should be remembered as a very distinct style, something different from any we have seen before for the mine or a fluorite combination. NOTE: these exhibit the photographic property of metamerism. They change colors from halogen and professional bulbs (more blue) to indoor fluorescent lighting and even natural sunlight (more green). Examples from both are shown here. The change is startling if you do not expect it, and quite pronounced in the right lighting.
