13 mm Round Magnetic Earrings With Faceted Crystal Set in A Wide Silver Bezal Setting

A brilliant 9 mm faceted crystal set in a modern plated plastic setting with a wide bezel that will complement any outfit.
They are each 13 mm in diameter and 8.5 mm high including the neodymium magnet and sold as a pair.

Held on with a nickel plated neodymium magnet attached to the earring and an 8 x 3 mm enamel painted ceramic magnet that goes behind your ear to hold it on.
These comfortable magnets use a magnetic field to hold the earrings on so they don't pinch at all like those old clip on earrings do.

Remember: The wider the magnets, the more comfortable the earring is.
If you have misplaced your metric ruler, remember that 13 mm=1/2 inch.
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.
