does anyone know how to play rank 456 in bejeweled stars?

 The stones are at the far right and have to be blown up. You can make power ups of the color on them or lined up with them for the first stone layer. Then to replace the blown gems in order to blow the second level of the stone, you can get a gem out there by throwing a gem leftward into the “jet stream” obstacle (the swirly looking thing) which will send it right out to sit on the stone. Gems used from the bottom half can not be replaced until some of the gravel is taken out to allow gems to fall down.
