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)!

A great selection and size choice of the gems I have been looking for. Very happy with the purchase.
It's pretty great having a whole lot of different gemstones to choose from. When doing crafts and jewelry making, it's great to have all kinds of options, and it's amazing how much cheaper it is to just purchase un-set gemstones and make the setting yourself, as opposed to buying fully-made jewelry already. It's also extra special since you made it yourself.
