I was looking for a site with every type of gem I could want for setting in luxury blades and assumed I would need to look outside the US, but GemSelect made it easy to get everything I wanted without leaving the house! Wide enough selection that I do not feel the need to look elsewhere and pricing the same.

I have been buying gems for several years off and on and love their selection and great low prices. I started out wanting to get an example of each type of gem but after looking at all the types of gems and reading about them I realize it is almost impossible for me to do. It took me years just to read about them all. Gem Select is the best gem site you can find. For information or to buy. Steve M.

I always enjoy the selection and the unique cuts I can find here. I would love to see more hex cuts tho! Maybe some rose cuts too!

Natural blue sapphire gemstones never go out of fashion, whether they are in the form of large or small stones, and round shapes are the most popular and versatile jewelry gemstone. Sapphire, with its Mohs hardness score of 9, second only to diamond, is one of the most valuable and wearable of all gemstones.

Blue sapphire is famed for its brilliance and rich blue color. Natural blue sapphire gemstones may be used in various jewelry designs, from engagement rings to earrings. Our blue round sapphire stones are available in various calibrated sizes. 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, sapphires enhance love and tune your spirits to one another. Also, it has been used to banish envy and jealousy as well as promote fidelity in marriage.

From this page, you can use our filters to find single, pairs, lots, faceted gems or cabochons by using the check boxes at the top. These tools help you to find the perfect blue round sapphire for your jewelry design.
