Why Buy Dumortierite Quartz from GemSelect?

GemSelect Certified Store Reviews

Overall Rating -> 10 star ratings

I was looking for high-quality amethyst on this site, and I was able to compare size, color, and weight in detail before making a purchase.

The website design looks dated and not particularly up to date with what you would expect from a site selling gemstones - however the product information is clearly laid out and well marked, with details for each product sold.

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!

I've purchased from here many times over the last decade+. I find the information easy to understand, helpful, and interesting. I have always been satisfied that I got exactly what I ordered. Pictures and descriptions are clear and unique to each stone.

I like the site, it's easy to navigate. There are sometimes items I'm looking for that aren't there, but mostly I can find what I need.
