RARE FORM

While most gemstones have a long and rich history, Tanzanite has only been in our consciousness since 1967 – when it was discovered within the foothills of Mt Kilimanjaro, Tanzania. Despite being new on the scene, this stunning blue-purple gem has made quite an impression, enjoying an exclusivity that even a diamond cannot match.

It was famous diamond-merchants, Tiffany & Co, who suggested a change of name from the geological ‘blue zoisite’ (because it sounded like ‘suicide’) to ‘tanzanite’ in reflecting its singular source. In fact, its rarity currently only found in one location on the planet – has earned it the nickname ‘the Generational Stone’, because all new deposits could be exhausted within one generation. This, along with its stunning deep blue hues, combine to make it highly sought-after. To put things into perspective – Tanzanite is even rarer than diamond. Get it while stocks last!

 

YOUR TANZANITE

Tanzanite symbolises maturity and elegance; its exclusivity making it a highly valued gem. Often a brownish colour when first found (like diamond), tanzanite is commonly heat treated to bring out the brilliant blues or violet shades.

Because Tanzanite is relatively soft, care needs to be taken when cleaning it. A soft cloth and warm soapy water is best, and the stone should never be exposed to extremes in heat or worn where it may be damaged.

 

NOTABLE TANZANITES

The largest faceted stone is 737 carats. But perhaps the most famous cut gem is the 242 carat ‘Queen of Kilimanjaro’, set into a tiara and belonging to Michael Scott – original CEO of Apple.
