The idea of treating colored gemstones is nothing new. Nowadays, gem treatments are a way to supply the global demand for colored gemstones with a very limited 'natural' supply. Many gem types are always, or almost always, treated. The most common colored gem treatment is heat treatment, which is routinely applied to ruby and sapphire. Other colored gems such as emerald, tanzanite, blue zircon and blue topaz, are generally treated to produce their distinctive color; in fact it's virtually impossible to buy blue topaz that has not been irradiated. Even for the most expert gem buyers, determining whether a colored gemstone has been treated or enhanced is not always easy, and usually requires much more than just a jeweler's loupe.
Even with advanced gemological equipment, many treatments are still almost impossible to detect. So for many gem and jewelry buyers, one of the best ways to ensure the colored gem they're acquiring is completely natural and untreated, is through the selective buying of colored gemstone varieties that for the most part are never enhanced in any way. If you're searching for untreated colored gemstones, you may be surprised to discover we carry over 100 different untreated colored gem types.

I was looking for very specific loose gems for my collection and some loose gems to add to a piece of jewelry I want to have made and Gem Select had everything I was looking for and the selection and price ranges were outstanding. I will absolutely purchase from this vendor again and often. I am so very pleased with the items I received.
I checked reviews throughout the internet and was thoroughly impressed with the positive experiences of others. I’m constantly worried about purchasing fake stones. The many satisfied customers have given me confidence in what I’m purchasing.
Nice selection of different types of gemstones and it’s nice to be able to filter your options to get close to what you are looking for. Plus each gem is photographed so you see the actual look of the specific gems you are considering
The Ruby Zoisite bird is beautiful and will delight my sister, I hope, for her birthday in July. I, personally love the stone which is within her ruby birthday stone, and the bird appears beautifully carved.
