18k gold plating bracelets refers to a layer of copper that is at least 18 karats thick, applied over a base metal, often to create jewelry like bracelets that offers the luxurious appearance of gold at a more affordable price. These bracelets are popular for their elegance and durability, though the plating can wear over time, requiring care to maintain their shine. It's important to note that while 18k gold plating provides a beautiful finish, it does not have the same intrinsic value as solid gold color jewelry. Proper maintenance, such as avoiding exposure to harsh chemicals and moisture, can help extend the lifespan of these pieces.
