Tanzanite Jewelry

Tanzanite jewelry has become incredibly popular in recent years and is also considered quite rare. Tanzanite jewelry is well known for its beautiful periwinkle color and trichroic effect, meaning its ability to exhibit three different colors when viewed in different directions. In good quality, the color is ultramarine to sapphire blue. Tanzanite jewelry in artificial light, however, may appear more amethyst violet. At its source, tanzanite occurs in a variety of colors, though it is common practice to heat-treat these crystals to produce better color gemstones for tanzanite jewelry.

Though it is called blue zoisite by scientists, which belongs to the Epidote group, it was Tiffany & Co., back in 1967, that popularized and gave tanzanite its tradename. They chose this name because of its country of origin, Tanzania. Tanzanite jewelry is often made with gemstones that have been cut especially to exhibit the orientation of deep blue to violet-blue colors. In doing so, some of the rough may be sacrificed in order to achieve better quality gems. This is another reason why the cost of tanzanite jewelry is exceptionally high.

Tanzanite is soft and brittle and great care should be taken while wearing it. Moh's scale of hardness classifies it as 6.5-7. Tanzanite jewelry should not be steam or ultrasonic cleaned, nor should it be exposed to sources of heat. A polishing cloth and gem cleaner may be used. Exercise caution when having your tanzanite jewelry repaired.
