GemSelect: Over 22 Years in the Gemstone Business! Thank you for trusting us with your purchase!
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.

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.
