The World Jewellery Confederation (CIBJO), the American Gem Trade Association (AGTA), and the International Coloured Gemstone Association (ICA) have long advocated for full disclosure of gemstone treatments. Despite efforts spanning decades—including AGTA’s introduction of a coding system in 1981 and a unified global disclosure agreement in 2010—undisclosed irradiation remains a pressing issue.
A particular concern has emerged over gemstones originating from Sri Lanka, where reports suggest that irradiation is being used to enhance yellow, peach, and padparadscha sapphires, as well as rubies. Fears over the stability of these treated gems have led some U.S. dealers to halt purchases from the region.
In response, the Sri Lankan Gem and Jewellery Association (SLGJA) has committed to strengthening testing protocols and promoting transparency in gemstone sales. Meanwhile, CIBJO, AGTA, and ICA are urging authorities in Sri Lanka and other countries to take immediate action to prevent further erosion of trust in the coloured gemstone market.
“Swift action is necessary to safeguard consumer confidence and protect the integrity of the industry,” the organizations stated in a joint declaration.
The debate over gemstone treatment disclosure is not new, but with consumer awareness increasing and markets becoming more scrutinized, industry leaders stress that transparency is essential for maintaining credibility and trust in the trade.
