I didn't exactly know what to do with Bloodstone's eyes for the makeup-looking markings that mega Sableye get, since there's no official reference for what color the markings are for shinies, sooooo I just had to try. Notice I arranged them all in order from tallest to shortest (Zircon and Jewel are the same height though I think).
