In 1967, we saw the discovery of a relatively recent gemstone called Tanzanite. This lush blue gemstone is only found in Tanzania, which is how its name was derived. This exotic new gem (which is a blue variety of zoisite) has colours ranging from bluish-purple to the more favoured pure blue hue.

Its vivid colour, transparent beauty, high clarity coupled and potential for larger cut stones has fuelled its popularity.

Tanzanite is the birthstone for December and represents the 24th wedding anniversary.

Reduced deposits of quality coloured gemstones and the demand for specific quality grades has led to the introduction of treatments. It has become common for coloured gemstones to be treated, although some processes are more acceptable than others. Tanzanite derives its colour from a heat treatment, as it is usually a brown colour.
