Heat Only Gemstones
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)!

when I need a colored stone I check gem select. a trusted supplier for at least 10 years for me. many of the online sites have gone black but gemselect continues to satisfy me. oh sure there are many windowed and poorly cut stones here so paying some attention is critical. remember these are not custom cut stones but rather cut by old methods and the aim is to keep weight up at the expense of optical perfection. remember that colored stones are about color as the first consideration. I just wish gemselect offered rough for those who want to cut it.
