How can you tell if Eisenberg jewelry is real?

To tell if Eisenberg jewelry is real, experts recommend seeking the opinion of a certified appraiser or knowledgeable dealer. Some Eisenberg pieces do bear artisan marks, which usually consist of a single letter or number positioned in a circle, but there is a lot of variability in these markings. In addition, many Eisenberg pieces are unmarked, and there are many convincing replicas of the brand's costume jewelry. For these reasons, an expert is in the best position to determine whether a particular piece is authentic. On 1stDibs, shop a variety of Eisenberg jewelry.
