A really nice puzzle game! I like your fade effects at the title screen and at game over--very smooth. I didn't realize at first that you could cycle all the way through the combinations (not just flip the columns), but I figured it out. It might also be nice if you had some kind of a fade-out or in-between effect for when the jewels clear (it's a bit abrupt right now how quickly the other jewels fall to take their place). Great use of the whole screen and good design!
