Bijou jewelry—frequently referred to as costume, fashion, or novelty jewelry—is crafted entirely from non-precious materials rather than fine gold, platinum, or certified gemstones. It utilizes accessible components such as base metals, brass, copper, plated alloys, glass beads, synthetic plastics, acrylics, and cubic zirconia. Designed specifically to complement modern seasonal trends rather than serve as long-term heirloom investments, bijou jewelry offers high aesthetic versatility at low retail prices.
