There is a report I have just received via email regarding what
appears to be a new treatment on blue sapphires that is not quite
diffusion nor a normal heating process. For those of you who don’t
belong to the AGTA, now would be a good time to join so that you
could also receive updates like these. For those of you who can’t
see how important it is to join organizations like this I will
entertain requests to forward the email on to you. It is critical
that all list members (i.e. all jewelers) keep apprised of these new
treatments as you are obligated to disclose treatments like this when
selling any sapphires.
