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.

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.
