4 polished Swazi agates from Africa turned into magnets. Stones glued on magnets measuring around 1/2 to 5/8 inch. Each stone measures around 1 inch wide and has its own unique patterning with rich colors of red, pink, purple and white throughout the set. Very strong rare earth magnet on each and glued with strong E-6000 adhesive. Polished and assembled in my shop.
