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 liked the selection of gems, and price. I did not like your PayPal process. I already have a PP account and you want me to sign up for another.
