Selenite was referred to as Moon Stone in the old Grimoires and has a history of being suitable to conjure the spirits with. This 5 inch diameter scrying ball has amazing refraction of light and its texture is quite good. With all selenite, it has a grain and when angled against the grain it is a beautiful reflective white but when angled with the grain it is nearly transparent. Various measures between the two would give a variety of textural angles for scrying.
