A heart necklace is a timeless and evocative piece of jewelry that centers around the universal symbol of love heart, crafted to convey deep emotions, commemorate significant relationships, or express personal style. Typically, it features a heart-shaped pendant suspended from a chain, though designs vary widely. The heart itself can be minimalist—a clean, polished outline in precious metals like gold, silver, or platinum—or elaborately detailed with engravings, filigree, or gemstone accents. High-end versions might boast a central diamond, ruby, or sapphire embedded at the heart's peak, symbolizing enduring love or individual milestones.
