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

The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.
