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.
