    TANZANITE GEM CRYSTAL
    Merelani Hills (Mererani), Lelatema Mountains, Arusha Region, Tanzania
    As anyone who has endured the "Cruise Ship Experience" can attest, the marketing of Tanzanite has taken on a life of its own. In spite of (or possibly because of) this situation, few intact gem crystals of Tanzanite manage to find their way into the hands of collectors. Anything with a "clean", gemmy area is fair game for the cutters and ultimately - the cruise ship trade. Rare indeed is the appearance of fine, large gem crystals on the international market. This is truly unfortunate, because the true glory of gem Tanzanite can best (and some say only) be appreciated when demonstrated by intact crystals such as this one. One reason for this, is that faceted gemstones are commonly 'oriented' and heat treated to minimize the display of "undesirable" colors; such as the beautiful, deep red hue that this Tanzanite displays when viewed from above. When contrasted with the deep cobalt blue and purple tints visible when observed from the front and sides; the specimen takes on a deeper aesthetic significance reserved only for those fortunate enough to handle such a crystal. The tetragonal prism contains numerous "clean" areas of intense color that would cut very significant ring or brooch stones, should one be Philistine enough to do so. Certain crystal faces appear repeatedly - producing a complex exterior, even though the crystal is, at heart, a simple one. On the back side is evidence of intergrowth with some other mineral, now vanished, producing an area with a druzy appearance. Luster is the glassy one typically exhibited by fine examples of gem material from this locality and the overall condition is outstanding. It stands some 4 3/8 inches high on its custom labeled acrylic base and the crystal alone measures a significant 3 ½ inches tall by 1 5/8 inches wide and is 1 ½ inches thick.
