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 visited several online loose stone shops trying to find rare stones. I finally found one that I've been looking for here, and very satisfied. Looking forward to receive the item in 3 weeks.

The purchasing process is fairly quick and straightforward and for me user friendly so it probably took more or less than 3 minutes to purchase and pay for the items. I wish there was a discount offer for multiple items to encourage us buyers to purchase more an incentive and add more sales in your end. Besides that, it's been a great purchasing experience and will continue to shop as I am a repeat customer and have bought from your store many times before. Thank you.
