DJR Expert Guide Series, Vol. 74 — How to Authenticate Antique Jewelry & Gemstones
Antique jewelry from the Georgian, Victorian, Art Nouveau, Edwardian, and Art Deco eras carries immense historical, artistic, and financial value—but it is also one of the most misrepresented categories in the entire collectibles market. Modern reproductions, recut stones, replaced settings, fantasy hallmarks, machine-made “antique style” castings, and altered pieces circulate widely across online marketplaces and estate inventories.
DJR Expert Guide Series, Vol. 74 — How to Authenticate Antique Jewelry & Gemstones gives you the complete, professional-level system used by appraisers, jewelers, and material analysts to evaluate age, construction, metal composition, hallmarks, gemstone identity, wear patterns, and authenticity with confidence. These are the same methods relied upon in estate work, fine jewelry appraisal, auction-house verification, and high-level gemstone examination.
Inside, you’ll learn how experts:
Evaluate metal composition, karat levels, period-specific alloys, solder types, and construction techniques
Identify correct-era gemstone cuts — table cuts, rose cuts, old mine, old European, transitional, early brilliant — and recognize optical behavior
Read hallmarks, assay marks, maker’s marks, country stamps, duty marks, and period-specific font styles
Distinguish handmade antique settings from modern cast reproductions
Recognize period-appropriate clasps, hinge designs, prong shapes, joinery, and hallmark placement
Detect replaced stones, modern prongs, recut diamonds, re-tipped settings, solder patches, and other alterations
Analyze natural patina, oxidation behavior, and genuine age-related wear patterns
Identify foil-backed stones, early gemstone treatments, Victorian pastes, synthetics, and post-1880 laboratory-created stones
Use loupes, UV light, magnification, gemstone testers, and refractive tools safely and correctly
Spot the strongest red flags: incorrect metal purity, modern fonts, machine-perfect symmetry, glass replacements, wrong clasps, added hallmarks, and misaligned stamps
Volume 74 provides collectors, dealers, jewelry buyers, estate handlers, and antique enthusiasts with a clear, defensible, expert-grade methodology for authenticating antique jewelry and gemstones—ensuring you can distinguish genuine period craftsmanship from modern imitations or altered pieces.
