Named for Tanzania, where Tanzanite was first discovered in 1967, tanzanite is the blue-to-violet or purple variety of the mineral zoisite. It’s become one of the most popular of colored gemstones. Lush blue velvet. Rich royal purple. Exotic tanzanite is found in only one place on earth, near majestic Kilimanjaro.
A deep saturated “sapphire” blue is the tanzanite’s most valuable color, although some favor gems with an intense violet blue hue. Exceptional tanzanite's display a very intense violetish blue with red flashes of pleochroic color. As with any colored gem, paler hues are more affordable.
Eye-visible inclusions decrease the value of tanzanite, this is particularly true in lighter colored stones, where they’re more visible against the gem’s body color.
Tanzanite is available in a wide range of shapes but cushion and oval cuts are the most common. Cutting orientation has a big impact on a gem’s face up color and value. Cutting to emphasize a gem’s bluish purple color usually wastes less than cutting it to get a pure blue or violetish blue hue.
Wash your tanzanite gently with mild detergent and a soft, clean, cloth. To avoid any damage store your tanzanite separately from other jewelry in it's own bag or box.
