Local designer handmade 14k gold filled cable Chain 7" inches. Faceted blue sapphire 6mm. Finished with lobster clasp. What Is Gold-filled Jewelry? Gold-filled is made from solid "Gold" and "filled" with other alloys. Gold-filled wears like solid Gold because its outer surface is solid Gold. Electroplating is NOT a part of this process. Gold-filled is created by using heat and pressure to fuse a layer of Karat Gold to high quality jewellery base metal. The bond produced is a permanent one. How Long Will Gold-Filled Jewelry Last? Gold-filled offers all the same physical characteristics as solid Gold such as beauty, durability, and strength, but at a fraction of the cost. With reasonable care, it will last a lifetime. How Do I Care For My Gold-filled Jewelry? Frequent cleaning is recommended to maintain its beauty. Wipe your jewelry carefully with a soft cloth to keep it clean and free of elements which oxidize. We recommend and use our Jewelry Polishing Cloths.
