DJR Expert Guide Series, Vol. 102 — How to Value & Authenticate Signed Vintage Costume Jewelry
Signed vintage costume jewelry from Trifari, Miriam Haskell, Eisenberg, Weiss, Schiaparelli, Coro, and dozens of other mid-century designers is one of the fastest-growing collectible markets today—but it is also one of the most misunderstood. Modern reproductions, fantasy signatures, glued-on tags, altered components, reissues stamped with older trademarks, and misidentified designs flood the online marketplace. Most collectors, resellers, and estate handlers cannot accurately determine originality, maker, construction method, or value without professional criteria.
DJR Expert Guide Series, Vol. 102 — How to Value & Authenticate Signed Vintage Costume Jewelry gives you a complete, professional, appraisal-ready system for identifying genuine signatures, evaluating materials, determining period correctness, recognizing construction patterns, spotting alterations, detecting reissues, and establishing fair market value with confidence. This guide follows the exact examination methods used by jewelry historians, appraisers, and advanced collectors.
Inside, you’ll learn how experts:
Authenticate signature plates, cartouches, stamped marks, engraved marks, and molded signatures
Compare decade-specific signature variations used by Trifari, Haskell, Eisenberg, Weiss, Schiaparelli, Coro, and others
Distinguish genuine hand-wired Haskell construction from glued modern imitations
Evaluate rhinestones, glass cabochons, enamel, japanned finishes, Lucite, Bakelite, celluloid, and alloy composition
Determine the correct decade of manufacture based on hardware, clasps, settings, plating, and assembly technique
Identify repairs, replaced stones, swapped components, incorrect hardware, and value-reducing alterations
Separate authentic originals from reissues, remakes, unauthorized reproductions, and modern fantasy pieces
Assess condition professionally, using rarity, colorway desirability, completeness, and period-correct wear patterns
Use auction archives, verified sold listings, and condition-adjusted comparables to determine true fair market value
Volume 102 equips collectors, dealers, estate professionals, and jewelry buyers with a reliable, defensible, professional-level method for evaluating and authenticating signed vintage costume jewelry—ensuring accurate purchases, confident selling, and long-term collection growth.
