Faceted polished Tanzanite gemstone set in Sterling Silver. Beautiful Blue/Purple hue super gemmy and gorgeous. The picture of the cuffs on my wrist are my two cuffs with different gemstones, my wrist is approximately a 7.5", on a smaller wrist the gemstones will sit a little closer together. It is slightly adjustable by gently pulling it open or pushing it closed, it twists to slip on the wrist. Sterling will tarnish, keeping it out of moisture and water will help delay the tarnishing. I use a jewelry cleaning cloth to polish my Sterling Silver on a regular basis and it does not tarnish. You can also keep it in a sealed plastic bag when not wearing it and that will help it not to tarnish as well. It is stamped 925 on the back side of the gemstone setting.
Tanzanite is a trade name that was first used by Tiffany and Company for gem-quality specimens of a mineral named zoisite with a blue color. Tiffany could have sold the material under the mineralogical name of "blue zoisite," but they thought the name "tanzanite" would stimulate customer interest and be easier to market.
The name "tanzanite" was given because the world's only known tanzanite deposit of commercial importance is in northern Tanzania. The name reflects the gem’s limited geographic origin. The mines are all located in an area of about eight square miles in the Merelani Hills, near the base of Mount Kilimanjaro and the city of Arusha. Tanzanite was not discovered in commercial quantities until the 1960s. In the short time since then, it has become the second most popular blue gem after sapphire.
It is one of a very small number of gems of any color that have been discovered and brought to strong consumer popularity within the past century. This rapid rise to popularity was accomplished mainly by Tiffany's promotion and tanzanite's beautiful blue color. Because of its growing popularity, Tanzanite was designated as a modern birthstone for the month of December in 2002.
The blue color of tanzanite is caused by small amounts of vanadium within the zoisite mineral structure. When vanadium-bearing zoisite is heated to a temperature of 600 degrees Celsius for about 30 minutes, the oxidation state of the vanadium is changed and that change causes or improves the blue color.
The heat treatment of tanzanite is very mild when compared to what is often done for gems such as rubies and sapphires. Those gems can be heated to temperatures between 1000 and 1800 degrees Celsius and held at those temperatures for days or weeks.
Today, nearly all of the gems being sold as "tanzanite" have a blue color that has been produced or enhanced by heating. A small amount of tanzanite in the marketplace has a blue color that was produced naturally through the heat of metamorphism without any treatment by people. This naturally blue, untreated tanzanite, is held in very high regard by some gemstone and jewelry buyers who seek it out when making a purchase.
The price history of tanzanite has seen many sharp rises and falls. These price changes have been related to the limited number of mines and the limited geographic location of the world’s tanzanite resource. Decisions and regulations of the Tanzanian government can have an immediate impact on the availability and price of the entire world's supply.
Tanzanite does not have the price insulation enjoyed by gems that are mined in multiple countries and on different continents. Events such as floods or mining challenges also have an immediate impact upon supply and price.
