A golden black heart necklace typically features a heart-shaped pendant that combines gold and black elements. The heart may be made of black enamel, onyx, or another dark gemstone, bordered by or set in a gold frame. The gold can be a shiny yellow gold, rose gold, or a more muted tone, providing a luxurious contrast to the deep black heart. The necklace chain is often fine and delicate, made of matching gold, which complements the striking centerpiece. The overall design is usually elegant and modern, blending bold color contrast with classic materials.
