Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

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
