Shop our large Ceiling Medallions Michelangelo Series Highly Colored and Decorative. Most of the Michelangelo ceiling medallions are of grand size in sized and of ornate design! Our Michelangelo Series of medallions come completely finished and ready to install on your ceiling. Their relatively low profile (ranges from 3" to 4") make them suitable for fairly low ceilings. They are built from fiberglass, pvc, and other high-impact materials giving them the strength so they will not warp with time.
