I liked the selection of gems, and price. I did not like your PayPal process. I already have a PP account and you want me to sign up for another.

I do enjoy this website and the wide selection. I would like to see more untreated stones. I also wasn't able to see my past order when I logged in.

This is the first time I have used this site. I was dissatisfied with the quality of gems and supplies elsewhere and decided to try GemSelect. They are awesome! I was thrilled to see the variety and the great web performance. There was the ability to search for information as well as gems. Things like the clarity rating system and caret weight of the gems. I have always loved making things and I have just started to make jewelry as a business. However I have never made a ring before and have always wanted to. On GemSelect I was able to find good quality gems to use in my creations. I am so glad the website is so easy to use. Thank you GemSelect.
