It's crazy they can tell an asha from a diamond just by a picture, that's scary!
Actually they can't.
Once there was an Asha Asscher posted that was accidently outed by us girls here because we were guessing based on the cut, and then someone lurking here saw us guessing and contacted the ring VENDOR and asked.
The Vendor accidently outed the stone as an Asha and the girl was publicly shamed, they had a field day on PS, it was really over the top.
And once I posted my ring there, because I was member of the Ladies in Waiting board and wanted to share my new ering with my friends there, eventually *I* got sick of the charade because I wanted to post my ring here, and a lurker here must have recognised my ring, because my thread was quietly deleted from PS - though no one "outed" me the mods just silently deleted the thread, I guess not to bring attention to the fact that dozens of PS'ers had been praising a stunning chunky antique stone which was a beautiful Asha ACC
I dont think I have ever seen or heard of THEM identifying a Asha (or even a Moissy) by the photos?
