Do you know what the rarest mineral is? I looked it up, and it said painite, but the source also said there are only 2 known crystals in existence, and to my knowledge there are more than that. Another source said that fingerite was an EXTREMELY rare mineral, and it made it sound like it was the rarest mineral IMO. So I ask you this question...what is the rarest mineral?
