Gold-Filled Earring Backs, Butterfly Nut
Best Seller
0 Reviews /
Avg Rating: 0 /10
14kt gold-filled scalloped butterfly nuts (earring back components) for jewelry making, or for replacing lost earring backs. Gold fill (also called gold overlay or gold-filled) is made by using heat and pressure to apply a layer of karat gold to a base of less costly metal. This produces a surface with karat gold. The minimum layer of karat gold must equal at least 1/20 of the total weight of the item. How is this different than gold plate? Gold fill is 50 to 100,000 times thicker than normal gold plating, and 17 to 25,000 times thicker than heavy gold electroplate (HGP). Questions? Call our friendly sales staff at 1-800-366-2156, or email us.
