Coating Stones

Does anyone out there know anything about the process being
used to coat stones. Re: White quartz with a red coating to
make it red quartz. I believe they’re using some sort of
optical coating, similar to that of prescription
sunglasses. Any info on the matter would be appreciated.

Thanks,
Benjamin Mark
