It''s my understanding that a lot of sapphires are beryllium treated. My main question is, are these treatment usually stable or do be-heated stones require special care? Do they eventually lose their color?
And, in case I am considering a heated stone, how can I verify that it is not Be-treated? It seems like this is not so easily done. Therefore, what is the market value per carat on ambiguous/BE-treated stones, in the event that I decide to buy one?
I am referring both to red ''songea'' sapphires I see on ebay as well as blue be-heated sapphires.
