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.

This is the first time I have used this site. I was dissatisfied with the quality of gems and supplies elsewhere and decided to try GemSelect. They are awesome! I was thrilled to see the variety and the great web performance. There was the ability to search for information as well as gems. Things like the clarity rating system and caret weight of the gems. I have always loved making things and I have just started to make jewelry as a business. However I have never made a ring before and have always wanted to. On GemSelect I was able to find good quality gems to use in my creations. I am so glad the website is so easy to use. Thank you GemSelect.
