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

All these questions, and I don't have to give any blood. What a Deal... I absolutely enjoy the Gem Select emails every month. This one today was special. I always say, I'll know it when I see it. This stone today was the One. Odd and Intriguing. Thank You So Much for all that you do.
