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 love the quality, presentation and the price of the stones. I love the identification card - report they send with each stone.

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!
