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.

Site worked well and helped me find a rock that matched what I was looking for. Well within budget and I trust it will show up, so that's definitely positive. Not much else to it. Satisfied.
