Tanzanite is the name used for the vivid violet blue color of the mineral zoisite. The violet blue color is almost always produced by heating brownish or greenish zoisite. But due to the market enthusiasm for tanzanite, other zoisite colors are being marketed under the tanzanite name.
Natural zoisite occurs in a number of colors, include blue, green, yellow, orange and pink. Strictly speaking, non-blue zoisite should be refered to as “fancy colored zoisite” or “fancy zoisite.” But because of the market success of tanzanite, all gem-quality zoisite tends to be sold under the name tanzanite.
In fact the rarest of all zoisite colors is pink, and good quality specimens are much sought after by collectors. The opaque massive form of pink zoisite is known as thulite and is relatively common. But the pink color is very rare in crystalline form, and transparent zoisite in any shade of pink is quite valuable. Collectible pink tanzanite should be natural and unheated, and uncut crystals specimens, as well as cut and faceted gems, are highly valued.
Pink tanzanite is so rare that many dealers have never encountered it. Usually specimens of pink tanzanite have a strong tint of orange, or are at best a salmon pink. Pure pink material, such as the specimens shown from our collection, is exceptionally rare.
