I love Gem Select! When you order what you see is what you get. As soon as you make payment that particular gem is taken off the photo album. That way the one you select is a one of that kind.

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.
