Absolutely love the website, selection and products. Can you guys add a gemstones with inclusions tab. I like those it'd be nice to have them all in one place but i do understand it would be alot of work to go through and categorize them. Thank you anyways

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!
