Sapphire, with its Mohs hardness of 9, second only to diamond, is one of the most valuable and wearable of all gemstones. Famed for its brilliance and rich blue color, sapphire actually occurs in a wide range of colors, including pink, yellow and green. Sapphire is every color of corundum except for red, which is ruby. The name corundum comes from the ancient Sanskrit "kuruvindam", while the name "sapphire" comes from the Persian word "safir". Sapphires are seen as the guardians of love. When given as a gift they enhance love and attune the spirits. Also, sapphires have been used to banish envy and jealousy as well as promote fidelity in marriage. From this page, you can use our filters at the top or on the left-hand side to find sapphire gems by color, shape, cut and so on.

Shop for sapphires that are untreated, or have only been heat treated (not fracture-filled or beryllium heated). Heat only sapphire and untreated sapphire is becoming increasingly rare, but still remains affordable. To find your perfect sapphire gemstones, use the filters at the top left-hand side. You can search heat only and untreated sapphire gems by color, shape, carat weight, size, price and other factors, to enable you to find the exact sapphire gems that you are looking for. All items shown are in stock and ready to be shipped.

The opals I ordered are absolutely beautiful, very fiery and well-cut. The pictures online didn’t do them justice. Shipping did take longer than expected (I chose the standard option), but the gemstones I received were definitely worth the wait.

I have purchased gems from Gem Select twice a year, for more than a few years.Gem select is the best place to buy gems. The selection and presentation are genuine. What you see is what you get, keeping in mind the carat weight, and measurements they have listed. Never have I been disappointed with any gem I have received from them. Nan

GemSelect has a great selection of smaller cabochons. Many other retailers do not. Plus, the photo of the stone is the one you are purchasing. Shipping from Thailand is nearly as fast as from within the US. Stones are tightly and neatly packaged.

Picking a garnet to match a setting. Good selection, It would have been better if a side by side color comparison was possible.
