How can you tell if a rhinestone necklace is vintage?

To tell if a rhinestone necklace is vintage, look on the clasp or the back of the pendant for a maker's mark. By snapping a photo of the mark and performing a reverse image search or entering a description of the marking into an online search engine, you can often identify the maker of a piece. Then, conduct further research to learn when the company or artisan was active and producing necklaces similar to yours. It is vintage if you estimate that your necklace is between 20 and 99 years old. Older pieces are antiques, while newer ones are contemporary. For additional assistance with dating your rhinestone necklace, consult a certified appraiser or knowledgeable antique dealer. On 1stDibs, find a wide variety of vintage necklaces.
