Buy Gemstones Heat Only: Natural Semi-Precious Gems; No Chemicals ...

Buy Untreated Gemstones, or routine heat only: Natural semi-precious gems that have no other enhancements other than routine heating, cutting and polishing. This means no chemicals, dyes, raditation or any other type of gemstone treatment process that many connoisseurs would consider the gemstone to be rendered as 'not natural' after such enhancements. In the case of sapphire and ruby, heating it considered routing -- and oiling for emerald -- are accepted by most of the gem trade as being perfectly fine as long as it's disclosed -- so these products shown on these pages will show only gemstones that have been routine heated (or completely untreated)!

I love the clear description of the certification options. It's very rare to see a gem site that offers a deep explanation of each institution that would certify the stone(s).
