Gemstone Treatment Alert: Ceylon/Sri Lanka Blue Sapphires

July 6th, 2011 No comments

Please use the link below for the full story and any updates I may list as I find out more information. But a quick summation is that Sri Lanka buyers have been buying up lots of the dark dark blue sapphire rough from Nigeria and Australia and have some how discovered a way to use Beryllium Treatment to lighten these overly dark and less valuable sapphires into close to top colors and far more valuable blues! The issue is many are just being sold into the Market as Ceylon/Sri Lanka origin materials and the only treatment(s) disclosed are “Heat” or “Heat Only” or “Heated”, no disclosure of Beryllium Diffusion/Treatment disclosed!

A friend and colleague, Hamid Usman Khattak(HUK) AG Gemologist from the Gems & Gemological Institute of Pakistan (GGIP)-Peshawar has shared with me some very unusual images I thought everyone would bee interested in viewing and giving their thoughts upon them. I was stunned!



Obviously the stone was cut to enhance the layout of the inclusions, but still, talk about wild!! Mother Nature has lots of tricks up her sleeves!

Once again, we can not thank our friend and colleague, Hamid Usman Khattak(HUK) AG Gemologist from the Gems & Gemological Institute of Pakistan (GGIP)-Peshawar for sharing this find and his wonderful images with us!
