Tanzanite

Tanzanite is a fascinating gemstone, crystal-clear and glowing in a glorious sapphire-blue colour shot through with flashes of purple. Its stunning brilliance and sparkle are superbly brought out by an expertly faceted cut. At RenéSim we supply tanzanites in the carat weight and cut of your choice – as either loose stones or integrated into a piece of jewellery.

Tanzanite – A rarity in the world of gemstones

Tanzanite is a gemstone which was only discovered comparatively recently. The first tanzanites were not identified until 1967, in north Tanzania at the foot of Mount Kilimanjaro. This location is still the only source of high-quality tanzanites in the world.
Although a further location has now been discovered in Pakistan, the stones mined there fall very far short of the fine quality of the Tanzanian stones.

Tanzanite and its magnificent play of colours

The finest tanzanites glow in a rich sapphire-blue that takes on tints of amethyst violet under artificial light.
A special feature of this gemstone is its pronounced pleochroism. Depending on the angle of viewing and direction of light, tanzanites vary in colour between deep blue, violet purple and yellow-brown.
In general, the larger a tanzanite is, the deeper and more intense its shade of blue. Smaller stones frequently have an underlying brownish hue. However, heat treatment brings out the fine colour of these stones.

Tanzanite – Gemstone of outstanding clarity

A major factor in the popularity of tanzanite is its exceptional clarity and transparency, which is brought out most impressively in faceted cuts.
Some tanzanites also feature a cat's-eye effect known as chatoyancy where the stone reflects a slim streak of light. This optical effect is best seen when the stone is cut as a cabochon.
