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

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.

Found a beautiful opal at a great price. I was not disappointed when it arrived. Even better in person.
