How can you tell old cloisonné from new?

To tell old cloisonné from new, first, consider the condition of the piece. Older cloisonné will often show signs of discoloration due to the natural oxidation process that occurs over the years. Colors on older pieces also tend to be less vibrant due to the techniques and materials used to produce them. You can also research the maker's mark on your cloisonné to learn more about who produced it and when the maker manufactured pieces similar to yours. If you still aren't sure whether your cloisonné is old or new, a certified appraiser or knowledgeable antique dealer can assist you. On 1stDibs, find an assortment of cloisonné.
