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

I searched for the size, dimensions and quality of the stones I was looking for and then compared and ordered.
