No problems. I had a minor address issue in the past and someone got back to me very quickly and we resolved the issue satisfactorily. I appreciated the quick, concerned response. So important when buyer/seller are so far apart in distance. Thank you Gem Select. Keep up the good work!

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.
