How can you tell if a necklace is antique?

To tell if a necklace is antique, first look for hallmarks that indicate the maker. If you locate them, you can consult trusted online resources to find out when the company or artisan was active. To qualify as an antique, a necklace must be at least 100 years old. The presence of materials that are no longer commonly used to produce jewelry, like bakelite, camphor glass, foil opals and paste, can be good indicators that a piece is an antique. Antique jewelry is also more likely to have European- and rose-cut gemstones than modern cuts like the brilliant round. Because it can be difficult to date jewelry on your own, you may wish to consult an expert, like a certified appraiser or experienced dealer, for assistance.
