Gold over silver is built for regular use: sterling silver provides the structural durability to handle daily wear, and the gold exterior protects against the surface degradation that frequent exposure would otherwise accelerate.
Quality & Value
The bead's material determines its jewelry classification: precious metals, diamonds, gemstones, pearls, coral, and amber place a bead in fine jewelry; glass, resin, and synthetic materials in fashion. The construction method is the same across both categories, but the material is what separates them in value, longevity, and meaning.
