Overall Rating -> 10 
I have purchased stones from gem select in the past and have been very satisfied. I expect to repeat that experience with this purchase as well
Overall Rating -> 9 
I was looking for a small gift for a friend- the process is the same as every other time and was very simple, and she even got her gift early! On the downside, there's no way to easily keep track of multiple Shipping Addresses, so if I want to send a gift to Friend A and to Friend B, I have to overwrite everything and it's a fair bit clunky in that regard.
