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

You Selected (8413): Heat Only Gemstones Clear All

Sort By:

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)!

Gem select is the most trustworthy web site for gems. What I see in the picture is exactly what I get. Size is indicated by carat weight, and not the picture size, as they are trying to give an up close view of the gem I am hoping to buy. It was so easy to find the stones I was looking for at a price I could afford.
