Gold-filled jewelry has 100x more gold alloy than gold plated & because that layer is so much thicker, it means gold-filled jewelry lasts longer & stands up to wear & tear better than gold plated. As long as the piece is well cared for, gold-filled jewelry can last many years. 14K Gold Filled Hamsa Opal Necklace | The Hand Of Fatima Dainty Protection Satellite Chain
