These cute little Sacred Heart earrings are made from 14K gold fill.
The hearts are about 1/2" long by 3/8" wide (13mm x 11mm), they are 7/8" from the very top of the ear wire to the bottom.
The material is 14K gold fill sheet. Gold fill is solid gold laminated with brass, it is not a plated material that will wear off. (Think of a wooden pencil with the lead on the inside and the wood on the outside).
