FAQ's

Due to the fact that tanzanite is only found in one place in the world and is formed as the result of a rare geological phenomenon, most estimates are that there is enough tanzanite in the ground to last for another 10-12 years.

Extensive geological research has proven that there is only one current source of tanzanite and its geology is so unique it has been described as a ‘geological phenomenon’.

Tanzanite is softer than a diamond and has a similar hardness to that of an Emerald, but is less brittle. Tanzanite measured 6.5 to 7 on the Mohs Scale of Hardness. Simple precautions should be taken to preserve its beauty. Tanzanite is ideally suited for wear in dress rings, earrings and necklaces, rather than everyday wear.  As such, we do not recommend Tanzanite in engagement rings that are worn every day.

Tanzanite is not as hard and durable as a diamond, and is not recommended for wear every day.

Tanzanite has what many would consider the finest blue hue in the world of gemstones. Tanzanite is one of the only trichroic gemstones known to man, meaning it has the ability to display shades of blue, violet and red. Depending on the formation of the gemstone, the colour is determined by the direction of the grain along the axis.

The deeper the colour of tanzanite, the more rare and valuable it is.

A larger stone would have greater depth and colour spread over a larger surface area. Therefore, larger tanzanite gemstones appear deeper in colour.
