Tanzanites are rarer than diamonds and make gorgeous gemstone engagement rings and jewellery


Tanzanites occur only in one place in the world – the East African state of Tanzania. They are blue with a fine hint of purple, creating different hues of colour depending on the intensity of light falling upon them.

For this reason, they are said to be pleochromatic – a rare characteristic for coloured gemstones. A tanzanite’s colour can also appear different when viewed under varying lighting conditions.

It is believed to be a magical gemstone, enhancing spiritual awareness and is used for converting negativity.
