Tanzanite Gemstone in Jewellery
|
Tanzanite is more than a thousand times rarer than diamond. Its great beauty and rarity make it an expensive gemstone. Tanzanite was introduced to the fine-gem market by Tiffany & Co in late 1960s. Tiffany coined the name Tanzanite as the thought it sounded better than blue Zoisite due to similarity of Zoisite to the word “suicide.” Tanzanite is not a durable gemstone therefore when mounted in a ring or bracelet special attention should be paid to ensure the stone is well-protected. Some traders advise that tanzanite is better kept for earrings, necklaces and pendants. Shop from our secure, Amazon-powered store Here, shop directly from amazon.com for tanzanite Jewellery.

Tanzanite Gemstone Care
As Tanzanite is a relatively soft gemstone it is not suitable for everyday wear, also for the same reason tanzanite should be stored separately from other gemstone. As tanzanite can be very brittle it can chip if exposed to sudden changes in temperature. Tanzanite should never be cleaned with an ultrasonic or steam machine. Tanzanite can be cleaned with most any commercial jewellery cleaner or mild soap and lukewarm water using a soft brush. Be sure to rinse and dry thoroughly after cleaning.
