Blue Topaz

What is Blue Topaz?

Blue Topaz is a stone in the Topaz Group. It is formed from white topaz which has been irradiated to become blue. The blue of the stones varies from a pale blue through to a rich electric blue to a deep metallic blue.

The Blue Topaz is the least expensive and most widely available Topaz

It is found in Australia, Brazil and Mexico.



Blue Topaz  dates from the 1980s when it was first realized that white topaz could be turned into electric blue stones by irradiation.


The Blue Topaz is associated with creative people such as writers.


All topaz is vulnerable to cracking. This can happen if the stone is set too tightly or from sudden temperature changes and should be treated carefully.

It should be stored away from other jewellery to prevent scratching and cracking.

A steamer or ultrasonic cleaner should not be used.

It should be washed in warm soapy water using a couple of drops of mild detergent. A sot toothbrush can be used to clean the stone which should then be rinsed, gently wiped dry and left to dry on a towel.
