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

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.
