I have been buying gems for several years off and on and love their selection and great low prices. I started out wanting to get an example of each type of gem but after looking at all the types of gems and reading about them I realize it is almost impossible for me to do. It took me years just to read about them all. Gem Select is the best gem site you can find. For information or to buy. Steve M.

I found what I was looking for...had to look up millimeters to inches. It would be nice to see something, like a quarter, in the pix to show relative size. I plan on buy loose gemstones for every month in the calendar

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.

Loved the price and the quality and the certification options which is the main reason why I buy. The guarantee is also a great reason to use gem select.

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.
