Designer costume jewelry from Trifari, Miriam Haskell, Hattie Carnegie, Coro, and Eisenberg has become one of the most heavily reproduced categories in the entire collectibles market. Originals from the 1930s–1980s carry true collector demand and strong resale value—but reproductions, fantasy signatures, added marks, and altered components dominate online marketplaces and confuse buyers daily.
DJR Expert Guide Series, Vol. 68 — How to Identify Original Signed Designer Costume Jewelry (Trifari, Miriam Haskell) gives you a complete, professional-level system for authenticating vintage designer pieces using the same criteria appraisers rely on: construction, hardware, materials, signature timelines, stamp variations, filigree work, plating characteristics, and red-flag inconsistencies.
Inside, you’ll learn how experts:
Identify authentic signatures, hallmarks, and correct-era stamp variations
Distinguish original construction methods from modern reproduction assembly
Evaluate rhinestones, glass beads, plating, filigree, and metal alloy quality
Recognize hardware clues: clasps, findings, earring backs, pins, and catches by decade
Separate true hand-wired Miriam Haskell components from glued modern imitations
Determine correct plating tone (including Haskell’s Russian gold)
Spot fantasy signatures, mismatched parts, altered pieces, and modern-added marks
Identify common marketplace scams and misrepresented “vintage” designer sets
Appraise originality, condition, maker significance, and long-term value
Volume 68 gives collectors, jewelry buyers, resellers, estate handlers, and antique dealers a complete, defensible method for identifying authentic designer costume jewelry—and avoiding the forgeries that dominate today’s online market.
