Tanzanite Guide

Tanzanite Guide

Tanzanite belongs to the Zoisite mineral and was named after the country where it was found in Tanzania. Masai tribesman Ali Juuyawatu was known to have found the first tanzanite crystal. This blue gemstone is found only in Tanzania at the foothills of Mount Kilimanjaro.

 

Color

Tanzanite is found in blue but its colour varies depending on its angle and it ranges from bluish purple, pure blue or a violet blue hue. It also displays reddish-purple, blue, deep purple, brown, grey and even green shades. The saturated colors are priced higher than paler colors.

 

Clarity

Most Tanzanite does not have inclusions that are visible to the eye. If inclusions are visible, it causes a decrease in value. The value of tanzanite is greatly lowered if it has inclusions that cause durability issues.

 

Cut

Tanzanite’s color display is determined by the cut given which in turn dictates the overall upper color of the stone. If the stone weighs less the value will also be less. In order to get maximum benefit, a tanzanite stone is cut with focus on the bluish purple color as this causes less wastage than when cut to focus on pure blue or violet blue. Hence there is an abundance of bluish purple tanzanites as compared to pure blue.

 

Carat

A number of shapes, sizes and interesting designs are created with Tanzanite as it is easily available. Tanzanite stones above 5 carats are found in deep and fine colors. The intensity of the smaller gemstones is generally less.

 

Enhancements

Tanzanite is commonly heated to enhance its blue hue. We believe in full disclosure of any treatment that a stone has undergone.
