Dedicated to Gem & Pearl Identification

Gem & Pearl Lab – Articles

It is important to verify that you have a natural gemstone and are aware of any treatments. Over a three to four year period I wrote articles for ‘The Jeweller’ (the retail trade jewellery magazine of the National Association of Jewellers). Please be aware that advances have been made in gem and pearl production and their treatments, since the articles were written.
