12 mm Aurora Borealis Blue and Silver Round Button Magnetic Clip Earrings

These beautiful little round magnetic earrings have an 11 mm round acrylic iridescent blue cabochon set in a silver bezel.
They are 12 mm wide x 8 mm high including the neodymium magnet.
Each earring is held on the ear with a 7 mm nickel plated neodymium in front and a 13 mm enamel painted ceramic magnet that goes behind the ear giving them a little stronger hold than my usual 5 mm magnet front.
Sold as a pair.

If you have misplaced your metric ruler, remember that 13 mm=1/2 inch.
Remember: The wider the magnets, the more comfortable the earring is.
If you are allergic to nickel, order only earrings that have both enamel painted ceramic magnets front and back since the neodymium magnets are plated with nickel.
