What is tanzanite?

A pretty basic question, but one that is worth asking. Definition: Tanzanite is the crystalline form of the mineral zoisite. Considered a "rare" gemstone, the zoisite crystals form in the presence of vanadium, which is a mallable, grayish-silvery metal. Tanzanite is found in only one place in the entire world, Tanzania, near Mt. Kilimanjaro. Tanzanite is customarily heat treated to drive off impurities and produce the beautiful purplish-blue color for which tanzanite is known. The resulting color is permanent and is considered an acceptable treatment.

How popular is tanzanite?

Tanzanite has been added to the list as one of the top-selling colored gemstones of all time. The U.S. buys approximately 80% of all tanzanite that is mined. Because of its outrageous popularity, tanzanite was added to the December birthstone list in 2004. Due to the fact that tanzanite is approximately one-fourth to one-third the cost of a similarly colored sapphire, it should continue its popularity for many years to come.

How hard is tanzanite?

Please see our in-depth discussion on tanzanite hardness here. Tanzanite has a Mohs hardness of 6.5 to 7.0 and is considered durable enough to be worn in practically any type of jewelry. As with any jewelry that is worn, it should be cared for. Tanzanite will scratch more easily than sapphire or diamond and should not be exposed to harsh chemicals and ultra-sonic cleaning.

What does tanzanite cost?

The answer depends on the depth of color and size. Commercial grade (low-end) tanzanites may be found quite inexpensively for approximately $100 to $200 per carat in the smaller sizes (<1ct). href="http://www.tanzanitefoundation.com/" style="color: rgb(0, 68, 119); text-decoration: none; ">The current price for richly colored tanzanites in the 3 to 5 carat range is approximately $550 to $700 per carat. Other factors determining value and price are cut, clarity, carat weight and recent news related to supply.

What does the supply of tanzanite look like in the future?

Due to the fact that tanzanite is only found in one place in the world and is formed as the result of a rare geolocial phenomenon, most estimates are that there is enough tanzanite in the ground to last for another 15 to 20 years. With advancements in deep mining applications, this time-frame could be extended.

When is the best time to purchase tanzanite?

Any time is a good time to purchase tanzanite. Some may consider its investment potential while others simply desire it for its good looks. We generally see price increases each fall due to short-term demands of the holiday shopping season. Our suppliers notify us of any price concessions when they have additional tanzanite inventory (which they are required to purchase as a sightholder) they need to sell and we pass any savings on to you.
