NEWS: AGTA Addresses Color Instability & Undisclosed Irradiation in Sri Lanka

On March 26th, Editor and Chief of the American Gem Trade Association (AGTA) Jennifer Heebner posted an article to the AGTA website detailing a new disturbing trend relating to improper heat treatments being applied to corundum coming out of Sri Lanka causing color instability.

She wrote, "AGTA has contacted Sri Lankan government officials and members of the Sri Lanka Gem and Jewellery Association (SLGJA) asking that both parties take necessary actions to protect the gemstone industry from isolated numbers of Sri Lankan vendors using radiation to create temporary and undisclosed treatments affecting the color of some corundum. The concern of color instability in yellow, pink, and padparadscha Sapphires from radiation has prompted many AGTA dealers to stop buying corundum from Sri Lankan dealers."
