Tanzanite

Tanzanite has a velvety purplish-blue unlike any other gem. Mined in only one place in the world, a five-square mile area in Merelani in Tanzania near the feet of majestic Kilimanjaro, tanzanite is exceptionally rare.

This gem was discovered in 1969 and named by Tiffany & Co., who was the first to bring it to market.

The secret to tanzanite's mesmerizing color is trichoism: crystals of tanzanite are three different colors from different directions. This means that blue and purple dance together in the depths of the gem as it moves and catches the light.

Gemvara's tanzanite is the best possible color for its size, more blue than purple. Only large gems show the most saturated colors. After mining, virtually every tanzanite on the market is heated to permanently change its color from brown to the spectacular violet-blue color for which this precious gemstone variety is known.

Of course, tanzanite is an ideal complement to all the rich blues, purples, and greens in your wardrobe. But the velvety depths of this gem are also beautiful worn with earth tones, from chocolates to rusts and golds.

Tanzanite is a birthstone for December, added to the official list in 2002 as a tribute to its beauty. It is also the gem of the 24th anniversary.

Tanzanite jewelry is a little more delicate than other gemstone jewelry and should not be set in a ring that will be worn during strenuous activity. Never clean tanzanite in an ultrasonic cleaner or have a ring resized or repaired without having the gem removed. Clean with mild dish soap: use a toothbrush to scrub behind the stone where dust can collect.
