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)!

I love GemSelect, personally. I browse their site almost daily to see all the new stones available. Their selection is pretty amazing. The quality isn't always the highest and the cut of the stones isn't always perfect. But for the price, and if you look hard enough, you can find a real gem, so to speak.

I would recommend to a friend because of the quality of the products purchased. The gemstone quality is very high and the gems purchased are beautiful. Any friends interested in having custom jewelry made would definitely be recommended to the site. Also, every shipment is handled with care and I am very pleased with that.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
