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

Always find more niche sizes/shapes as my unconventional designs require from this website. Recommending to fellow designers in the creative atmosphere on the usual, specially due to the quality and certification of gems.
