A handful of gem lapidaries around the world marketed tanzanite in the late 1960’s. The gemstone found its way to New York where Tiffany made the stone famous.
The unique, deep=blue tanzanite is only found in Tanzania and is characterized by its trichroism, three different colors when viewed from three different directions.
Tanzanite has what many would consider the finest blue hue in the world of gemstones. It has the ability to make even the most beautiful sapphires appear to be lacking in colour. As a result, tanzanite jewellery has gained momentous popularity, and tanzanite has become one of the world’s most coveted gemstones.
The deeper the colour, the more valuable the gemstone, and has been established that consumers naturally gravitate towards gemstones of deeper colours. Tanzanite gemstones of intense colour are more valuable because they occur much more rarely in nature. The finest tanzanite colours in the world make up only 1% of the world’s tanzanite production. Larger tanzanite gemstones are usually deeper in colour, and it is unusual to find an intensely deep tanzanite that weighs less than 5 carats.
Tanzanite is native to Tanzania and no other place in the world has this precious stone. These stones can only be found in a 4km strip of land on the outskirts of Mount Kilimanjaro. Because tanzanite comes from a single source, they are estimated to be 1,000 times rarer than diamonds.
Gemologists believe that at the rate tanzanite is getting mined, they will be depleted. Rough tanzanites might only be available for 10 or 20 years. After that, no more new stones will be available. The stone will become extremely precious and only a select amount of people will be lucky enough to have one of these magnificent gems in their possession.
