Overall Rating -> 8 
I've purchased things from GemSelect before. What you see is what you get, which is not always the case with gem sites online. You can find some good value with gem select, and I will buy from them again.
Overall Rating -> 10 
GemSelect offers excellent choices, prices & service- highly recommended! Unfortunately, prior to ordering a replacement gemstone, my jeweler neglected to mention it needed to be one that was a'cushion cuta' to fit the existing mount. Have yet to return/exchangea'
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.

GemSelect is always my first choice for purchasing gemstones. The fact that the gems are always exactly as described and pictured on the website has earned my trust many times over. Even when I don't buy, I still love browsing all the beautiful stones. My new favorites are the bright green Tsavorites!
