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.

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc
