I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.

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.

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

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!
