Exotic tanzanite

This is our beautiful Indjo ring set with a blue faceted tanzanite and white diamonds on satinated natural white gold. Indjo is one of our most successful lines, almost an iconic piece for Brusi.

The ring is easy to wear and full of personality, reminding classic jewellery and still keeping the distance from the classic patterns of high jewellery.

Details that make the difference are the not perfectly regular oval shape of the tanzanite and the finishing of gold which is kept in its natural colour and matt brushed by our talented goldsmiths.

Tanzanite is a popular gem nowadays much do you really know about it?

We checked it out for you. See what was found out.

Tanzanite is the blue/violet variety of the mineral zoisite. It was discovered by Manuel d'Souza in the Mererani Hills of Manyara Region in Northern Tanzania in 1967, near the city of Arusha and Mount Kilimanjaro.

Scientifically called "blue zoisite", the gemstone was renamed as tanzanite by Tiffany & Co., who wanted to capitalize on the rarity and single location of the gem, and thought that "blue zoisite" (which might be pronounced like "blue suicide") wouldn't sell well. Tiffany's original campaign advertised that tanzanite could now be found in two places: "in Tanzania and at Tiffany's".

From 1967, an estimated two million carats of tanzanite were mined in Tanzania before the mines were nationalized by the Tanzanian government in 1971.

So eventually after 1971 tanzanite was not belonging to Tiffany only anymore!

Something else I was not prepared to find out is the fact that in its rough state tanzanite is reddish brown, not blue or blue/violet as we normally see it when mounted in jewellery sets, basically requiring a heating treatment to bring out the blue violet of the stone.

Since heat treatment is universal, it has no effect on price, and finished gems are assumed to be heat-treated. Gemological Institute of America states that the source of heating is gemologically undetectable, but is assumed because of its prevalence.

This telling us that tanzanite is always heat- treated.

We found this very interesting “Tanzanite Journey” , we leave you with the link and some pictures that have been touching us very deeply.

Next time you will be visiting a jewellery shop you will look at tanzanite with different eyes, we are pretty sure of this. And we will be buying it with different eyes too.

Yes , remember...

Lush blue velvet. Rich royal purple. Exotic tanzanite is found in only one place on earth, near majestic Kilimanjaro.

After leaving Tanzania and Kilimanjaro it is cut mainly in Jaipur (India) and then sold all around the world to jewellery manufacturers and collectors.

Here above some declinations of tanzanite jewellery in a pure BRUSI style.
