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.

Site is easy to navigate and the variety is great and how often new products are added is also great.

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
