✦ABOUT BI-COLOR TANZANITE✦ Fancy colored Tanzanite make up less than 10% of all Tanzanite mined. This means that Bi-Colored Tanzanite is around 10,000 times rarer than a diamond.
Technically known as 'Fancy Zoisite' by gemologists, trade names include 'Bi-Colored', 'Chameleon', 'Peacock', or 'Ocean' Tanzanite. The most common colors are similar to a peacock feather – a mixture of blues, greens, and purples. These stones are colored the way they are due to a rare difference in chemical composition – it is not linked to the heat treatment. They have more chromium and less vanadium than the majority of Tanzanite. It is possible to find pieces that show a clear distinction between a greener form of Tanzanite and the blue form within one gemstone as a 'split' – but these are exceptionally rare.
The Tanzanite which tends to command the highest prices of all are those which display yellow, champagne, or pink colors. These are the rarest of all and are the most highly prized.
