Overall Rating -> 10 
I have purchased stones from gem select in the past and have been very satisfied. I expect to repeat that experience with this purchase as well
Overall Rating -> 10

Overall Rating -> 10
Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.
Overall Rating -> 9 
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.

Overall Rating -> 10
They have a wonderful selection of gems of all sorts, shapes, cuts, and quality. I am very particular about the quality of stones I buy, and found many with VVS clarity and excellent cut and polish. I am thrilled with each of the stones I purchased, and would definitely recommend GemSelect to everyone.
