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

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.

GemSelect offers excellent choices, prices & service- highly recommended! Unfortunately, prior to ordering a replacement gemstone, my jeweler neglected to mention it needed to be one that was a'cushion cuta' to fit the existing mount. Have yet to return/exchangea'

I found the filter options excellent. Yours was the third site I visited (asked chat got for reputable online sellers of loose gems) and the first I purchased from as I was able to easily find what I was looking for.
