Tanzanite is a rare and precious blue/violet gemstone discovered in 1967, just below Mount Kilimanjaro in Tanzania. The colour of tanzanite can appear differently depending on the type of light it is being viewed in.
The spectacular colour of this precious gemstone is due to a rare characteristic called “pleochrism” which causes the gemstone to portray magnificent differing shades of violet and blue.
The tanzanite stone is actually quite ‘soft’ and is not recommended for rough wear. It also pairs beautifully with diamonds in jewellery.
The stone is graded in a similar manner to which diamonds: colour, cut, clarity and carat weight of tanzanite all determine its value, and the deeper the blue/violet colour, the rarer and more valuable the tanzanite.
Even today, the only known source of tanzanite remains its original source – which could mean the stone becoming even more rare in years to come.
