"I calibrated this gem as soon as I got it. It was not a 7x5 but rather a 6x4. A little disappointed by this, color is good, clarity is there. For the current price of tanzanite still a decent deal."

Fast Facts
| The mineral zoisite was discovered around 1805 in the Austrian area by a Baron for whom it was named. It was usually brown in color, often nearly opaque. |
| The discovery by accident of the tanzanite version, in the late 1960's was a great surprise in Tanzania Africa, where it was first thought to be sapphire crystals. |
| The name Tanzanite was coined by Tiffany who had first and exclusive rights to the pretty blue violet mineral for many years. |
| Wearing a well-cut Tanzanite communicates self-confidence, individuality, and maturity. |
 Its brilliant color and its exclusive origin in Tanzania combine to make Tanzanite a unique and highly sought after gemstone. |
|
Tanzanite is a variety of zoisite. It has naturally occurring shades of blue, green, yellow, pink, brown and khaki but virtually all gemstone quality crystals are heat treated to produce the highly valued shades of sapphire blue, amethyst and blue violet. On Mohs’ scale of hardness, tanzanite is 6.5-7. The prime source of all the world’s tanzanite is in Tanzania near Arusha.
