I was able to find what I wanted very easily!
Overall Rating -> 10
This was my first experience with this company. I had no difficulty finding the item I wanted, and checking out was a breeze! Ia'm hoping my item arrives quickly, intact, and of good quality. Overall, this was a very satisfactory experience.
Overall Rating -> 10
My experience has always been fantastic. Today I saved 6 gems to email a customer looking for a particular color blend to fit into an east west setting, so her options were limited, but we found one she wanted, deleted all the others in the cart and order the gem she selected. It was helpful to be able to put them in the cart so I could save them until she selected the one she wanted without having to research all of them again.
Overall Rating -> 10
I liked the selection of gems, and price. I did not like your PayPal process. I already have a PP account and you want me to sign up for another.

I've purchased things from GemSelect before. What you see is what you get, which is not always the case with gem sites online. You can find some good value with gem select, and I will buy from them again.
