Tanzanite

Tanzanite
Tanzanite Gemstones at The Ross Jewelry Company in Atlanta, Georgia.

Tanzanite is the name given to transparent blue zoisite. Tanzanite was discovered in 1967 and named after the location of its discovery, Tanzania. This sparkling stone was introduced into jewelry in 1969 by Tiffany & Company of New York.  And . . . the magnificent 18K white gold Tanzanite ring below was designed and created by The Ross Jewelry Company of Atlanta.

Custom Designed Tanzanite Ring

Tanzanite has become the most popular gem stone in the world today after the “Big Four” (diamond, ruby, sapphire, & emerald). It is believed that the Masai herders were the first people to discover this gemstone. According to popular myth, a lightning strike near the Merelani hills set surrounding grasslands on fire. When the Masai herders returned to the area with their livestock, magical blue stones appeared on the ground. When a Portuguese geologist, named DeSouza, traveled to this area in Tanzania, he saw the magnificent blue stone and assisted Tiffany & Company in introducing this exciting discovery to the world.

Coloration
Tanzanite is usually blue, lilac blue, or deep violet blue, but other colors are possible including green , yellow, pink, brown and khaki. These colors and also paler blue stones are often heat treated to produce the preferred deep blue color. Tanzanite is slightly fragile, and can fracture badly, ultrasonic cleaning should be avoided, but otherwise it is very suitable for jewelry, being a very beautiful stone, similar to sapphire.

Famous examples: A specimen named "The Midnight Blue", of 122.7 carats is located at the Natural History Museum in Washington, DC. We provide discount cards to our customers for the gift shop in the Smithsonian Institute, home of the Natural History Museum.

Treatment
This is a gemstone you probably would never consider if it were not treated. When heated to 600 degrees Celsius, greenish to brownish zoisite undertakes an incredible metamorphosis, resulting in the creation of this vibrant blue to blue violet gemstone, Tanzanite. With hardness between 6 and 7 on the Moh’s scale, Tanzanite is quite fragile, and for this reason, ultrasonics should never be used to clean this precious gem stone. However with an appropriate setting and some care, all kinds of tanzanite jewelry including Tanzanite rings will provide their wearer’s with endless pleasure. Dazzling as Tanzanite earrings and Tanzanite necklaces, this rare gemstone speaks volumes about the wearer’s personality and sense of style.

Sources
With vast deposits in the northern part of the country near the Merelani hills, Tanzania is the primary commercial source of Tanzanite. Very small deposits have been found in Kenya, but were not considered large enough for commercial purposes until recently.

With Tanzanite’s ongoing popularity even these small deposits are now being mined and have even been the source of armed disputes.

Evaluation
As with most gemstones, lighting condition is the most critical factor when evaluating the value of these gemstones. Tanzanite will display the most blue under daylight, while the violet shade will be more apparent under incandescent light. The stone which commands the highest value is generally the one which displays minimal violet, even when it is viewed under incandescent light.

It is common to find flawless tanzanite crystals; therefore, the stone should not contain too many inclusions.
