Completely would recommend this company to any gem collector, jewelry store, or someone looking for a gemstone to repair their jewelry. There is an abundance of choices at great prices! If you don't see what you need exactly the customer service department will go above and beyond to meet your needs. Shipping is very reasonable! The gemstones always arrive well before the expected arrival date. This company has very high standards of meeting their customers needs! They are the number 1 company I go to when looking for any gemstone. They are also very detailed in their descriptions so there is no confusion at all as what you are purchasing! Highly recommended!!!!

If you want a gem that you can trust to not be treated, or if it is it's disclosed this is the place! There's something for everybody. I really like knowing that the picture of the item is the one I'm buying, not a sample or stock photo. If you make jewelry, buy gems here! You can even buy a gem and have it set by a jeweler. Again, they have an amazing inventory, and prices are more than fair. You won't be disappointed! I just wish they sold uncut gems. Sometimes I just want a specimen in the crystal form. I'm surprised they had no quartz from Arkansas, but they have a great selection of anything I've ever looked for.

I was looking for a tourmaline but although there were numerous beautiful stones to choose from, there was none that fit my need. Then I thought of some other beautiful stones I love and sunstone came to mind. I so thrilled when I was able to find the most gorgeous sunstone and with the exact specifications of my need. GemSelect makes it extremely easy to find the exact stone your looking for quickly and check out is just as easy to go through. I would (and have) definitely recommend GemSelect because of the large selection of stones, ease of use, and fast affordable shipping.
