Fake jewelry is more common today than ever before, and counterfeiters have become increasingly sophisticated. Gold-plated items are stamped as solid gold. Cubic zirconia and moissanite are passed off as natural diamonds. Synthetic gemstones are mixed into estate pieces. Designer jewelry features forged hallmarks, incorrect fonts, and artificially aged finishes. These problems cost collectors, resellers, and families millions of dollars every year.
DJR Expert Guide Series, Vol. 24 — Red Flags: Identifying Fake Jewelry, Diamonds & Gold reveals the same warning signs professionals use to distinguish genuine jewelry from counterfeits, plated metals, imitation stones, fraudulent hallmarks, and poor-quality reproductions. This guide teaches you how to examine metal behavior, gemstone optics, craftsmanship, weight, solder work, hallmarks, and construction clues to determine whether a piece deserves further testing or professional authentication.
Inside, you’ll learn how experts:
Identify plated, filled, bonded, and counterfeit gold
Spot fake or tampered hallmarks and mismatched stamps
Distinguish diamonds from CZ, moissanite, and synthetic stones
Evaluate gemstone optical behavior under magnification
Use weight, density, magnetism, and metal reaction clues
Recognize counterfeit designer jewelry through fonts and craftsmanship
Detect poor-quality solder, replaced stones, and construction shortcuts
Evaluate estate and secondhand pieces for hidden red flags

Whether you’re buying for investment, reselling, handling estate pieces, or building a long-term collection, these techniques will help you avoid costly mistakes and identify genuine value with confidence.
