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.

GemSelect is always my first choice for purchasing gemstones. The fact that the gems are always exactly as described and pictured on the website has earned my trust many times over. Even when I don't buy, I still love browsing all the beautiful stones. My new favorites are the bright green Tsavorites!
