Tanzanite is a gorgeous gemstone of striking brilliance and breathtaking blue purple or purple blue color.

At first, the stone was called Blue Zoisite but it was thought in the jewelry trade that the name sounded like blue suicide and would not sell well. Hence, as a part of the marketing campaign, the gemstone was renamed by Tiffany after the country of its origin, Tanzania.

Tanzanite is the blue or purple variety of the mineral zoisite (calcium aluminium hydroxy sorosilicate) which has the chemical formula of Ca2Al3(SiO4)(Si2O7)O(OH).

Contrary to the other gemstones which are known to mankind since ancient times and steeped in history, this is a truly modern gemstone discovered only recently in 1967.

It was the Masaai tribesmen of Tanzania who stumbled upon the shining blue crystals in the foothills of Tanzania’s Mount Kilimanjaro in 1967. It is fabled that the brown crystals lying on the parched earth were caught in a fire lighted by lightning that struck the grass-covered hills. As Tanzanites are brownish in color in raw state, the crystals lying on the surface were never seen. After the grassfire had heated the stones, they turned a bright, sparkling violet-blue. The Masai herders grazing cattle in the area spotted the beautiful blue color, becoming the first collectors of this gemstone. Initially mistaken for Sapphire it was later correctly recognized as belonging to the family of mineral Ziosite.

In the rough state most this stone is predominantly brown. Heating upto 500 -600 degrees centigrade leads to this color to change to blue. This is a permanent and stable change. Practically all gemstones of blue violet color have been heat-treated to enhance the color. With the heat treatment, the gemstones do not alter in quality, only in appearance.

Similar to other gemstones, while selecting a tanzanite gemstone, the four Cs should be considered which are as under:

Color

Color is the most important aspect to be considered. The unanimously acknowledged official grading system for colored gems is the Gemological Institute of America (GIA) system but other grading systems are also in existence.

The GIA grade for stones with the most desirable color is bv 6/5 or vB 6/5 and is reserved for the deep blue stones with a hint of violet. The other industry grades given to such stones are AAAA or AAA. These are the best quality investment worthy tanzanite gemstones.

As the color fades, the GIA grades given are bV 6/4 (other grading systems A or AA) and GIA grades bV 4/4 (other systems B).

The most remarkable attribute of Tanzanite is that most of the good quality stones include a Trichroic effect. A Gemstone possessing Trichroic effect can reflect 3 unique colors at a time based on the angle from which you look at the stone. One direction is blue, another purple, and another bronze, adding subtle depths to the color.

Clarity

Clarity is the second most important factor of the 4 c’s when determining Tanzanite quality. Clarity refers to how inclusion-free a gemstone is. Once again there is the GIA system along with other trade based systems in use. Tanzanite should be at least eyeclean but preferably loupeclean too. Top stones are loupeclean. The GIA grades for clarity are VVS very very slightly included, VS very slightly included, SI1 – SI2 slightly included and the lowest grade I1, I2 and I3 given to imperfect stones.

A top quality stone must be of VVS grade. A lower clarity grade will affect the value downwards and indicates a lower grade stone.

Carat Weight

Generally tanzanite gemstones stones come in the one to ten carat range size. As weight increases stones in the same quality gemstone will cost you more per carat.

The gemstone goes well with every kind of jewelry be it Yellow Gold, White Gold Or Diamonds. But since it is a relatively soft gemstone with a hardness of 6.5 on the mohs scale of mineral hardness it is normally worn as an earring or pendant. It is bezel set in a ring to give it protection.

Don’t expose the gemstone to sudden changes of temperature like going from hot tubs to very cold water and reaching from ovens to a cold sink.

You should be careful with your Tanzanite jewelry and you should not wear it while doing work like gardening, washing clothes or cooking where there is a chance of physical impact of the stone with hard surfaces.
