While this a guide to the products they sell, it's a good overview of what's out there...

Thanks. It is really useful. For some Enhancement procedures I didn't even know they existed.

These links aren't bad either:
http://gemologyonline.com/treatment_symbols.htm
and
http://gemologyonline.com/treatment.html

Does anyone ever check the links on the left?

[lyric]

Thank you for the reminder Barbra!

The links on this web site are indeed excellent and very valuable.
I for one plead guilty as I sometimes forget to check them first.
