Overall Rating -> 10 
I always purchase my stones from GemSelect, their products are high quality and customer service is always great. I also like the fact that I am able to purchase unique items
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.
