Loved the price and the quality and the certification options which is the main reason why I buy. The guarantee is also a great reason to use gem select.

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.

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!

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!

The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.
