Discovered in the late 1960s in Tanzania, and found exclusively in this tiny area of the world, tanzanite exhibits a rich violet-blue color for which the gemstone is treasured; often it is heat-treated to achieve this color. Colors range from blue to purple. Tanzanite gems that are medium dark in tone, vivid in saturation, with slightly violet blue hues command premium prices. As tanzanite can be less expensive than sapphire, it has often been purchased as an alternative. However, it has increased in popularity and now is valued more for its own beauty and brilliance than as a sapphire substitute.
Caring for your tanzanite jewelry is a simple process that will ensure that your gemstone maintains its beautiful sparkle. The best way to keep your gem clean is to bring it to your local Helzberg Diamonds store for a complimentary cleaning and inspection. At home, you can brighten your tanzanite jewelry by gentling wiping the gemstone with a jewelry polishing cloth and warm water.
