Tanzanite's color, poised intriguingly between blue and violet, is unlike that of any other gemstone. Indeed, its range of unique shades - vibrant, individual and youthful - gives tanzanite a strong, immediately recognizable identity, and contributes to its special positioning in both the gemstone and fine jewelry markets. Kaleidoscopic, distinctive and desirable

In geological terms, tanzanite is trichroic. This means that in its rough form it radiates three different colors from each of its crystallographic axes, namely blue, violet and burgundy.

Once cut and polished, the stone becomes a kaleidoscope of royal blue, violet, indigo, lilac and periwinkle shades. Different hues appeal to different tastes.

Larger stones tend to exhibit more intense color, fire and brilliance, and richly colored tanzanite typically commands the highest prices.

Matching pairs fetch a significant premium over single tanzanite because of the rarity of finding two tanzanites of identical color. Given that the probability of finding rich color in smaller sizes is so remote, small tanzanite of intense color are currently regarded as excellent value.

Demand for tanzanite among the world's jewelry designers and manufacturers is growing as knowledge of its exquisite color and diminishing source spreads.
