[Rockhounds] Thai rubies

[Tim Fisher]

My friend said to google leaded glass treatment, and never use an ultrasonic cleaner or get them near a torch.  Also if they were for your use they should be fine, but if they were intended for commercial use it's definitely not fine. If they were misrepresented as untreated you can email me the people involved and he can look into it. He definitely has some pull in the industry.

That would take some off, but the rubie/sapphire pieces are rough.
Tumbling would not remove the coating from the crevices.
