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!
