Start by deciding what “real” means for the necklace. A piece can contain genuine shells or cultured pearls while still having gold-plated hardware. It can also be well made without being solid gold or a natural pearl. Our team recommends identifying each material separately rather than judging the whole necklace by one clue.
Real shells usually have natural variation in color, thickness, and surface texture. Identical shapes or a uniform painted finish may point to molded components, but appearance alone cannot confirm the material. Pearls deserve the same care: cultured pearls are real pearls, while imitation pearls are typically made with a coated bead. Under good light, look for subtle differences between pearls rather than expecting every one to match perfectly.
For gold-colored parts, find any mark on the clasp or a nearby tag. Marks such as 10K or 14K can indicate gold content; “GP” commonly indicates gold plating. A stamp is a useful clue, not a guarantee, and an unmarked clasp does not automatically make a necklace fake. A magnet can reveal some base metals, but a nonmagnetic result does not prove a piece is gold.
Gently examine the clasp, jump rings, stringing, and attachment points. Components should feel secure, with no sharp edges, flaking finish, or beads that appear ready to slip off. These details speak to condition and construction, not necessarily whether a shell, pearl, or metal is genuine.
Avoid scratch, acid, or heat tests at home; they can permanently damage delicate materials and finishes. If the necklace is valuable or its materials affect what you are willing to pay, ask a qualified jeweler to examine it. For a coastal style that brings several materials together, you can explore our shell, starfish, pearl, and gold necklace guide as you consider the look you want.
Not by itself. A stamp may identify gold content or plating, but it can be inaccurate; a jeweler can test the metal if you need a reliable answer.
