Tanzanite: A One Source Gem
Did you know, Tanzanite is a one source gem? This remarkable blue to purple blue gem comes from one place in the world.
The gem is mined in Arusha, near Mount Kilimanjaro, in Tanzania. There are some tiny amounts found in a neighbouring Kenya. Geology doesn’t recognize political boundaries, I guess.
Tiffany & Co introduced the lively blue gem to the jewellery world in 1967. Before that, it was not known in the gem world.
Tanzanite is most prized for bright blue colour and for being very free from visible inclusions.
Because it is a one source gem, we always wonder when the source will run out.
There are hardly any gems that are only found in only one place, making tanzanite genuinely remarkable.
