Friggin' breath-taking. Apart from being the size of a small planet - these are reversed. They are coated on the faceted, curved side, so that you look into the gem to see the effect of the faceting and coating on the other side of a well of crystal. Makes you just want to carry it around and stare at it all day. Technically, they are "unfoiled" - according to the packaging. The end result is "very, very shiny and sparkly" though.
