Product Description for Min .75ct 6.5x4.5mm Emerald Cut Tanzanite
Tanzanite was discovered in 1967. It has a unique violet-blue to blue color that only Ceylon sapphire and iolite come close to matching, with red-violet flashes. Tanzanite ranks a respectable 6.5 to 7 on the Mohs' scale, but loose stones and jewelry like rings and bracelets need to be treated with care to prevent damage. Tanzanite is only found in one place in the world, Tanzania, and the continued availability of tanzanite is uncertain, which increases its rarity and its price.
