Measurement: 18" long Materials: -24kt gold overlay round box chain - 3mm small or 4.5mm large chain thickness Our 24kt Gold Overlay jewelry is crafted using a high-quality brass base coated with an advanced acid gold electro-depositing process, applying 20-30 microns of 24kt gold. This technique produces a durable and long-lasting finish, far superior to basic decorative gold-plated costume jewelry, which typically features 5-7 times less gold. Acid gold plating, originally developed for the electronics industry, offers excellent wear resistance and makes our Gold Overlay jewelry a reliable alternative to solid 14kt gold. This option provides a luxurious look and feel without the high cost of solid gold. For most people, Gold Overlay jewelry is a fantastic, long-lasting choice. However, if you tend to experience issues with gold plating changing color quickly, we recommend considering solid gold-filled or sterling silver options for even greater longevity.
