You are buying, selling, or having jewelry repaired. You have heard stories of people being cheated — stone swapping during repair, gold-plated brass sold as solid gold, inflated appraisals that make a piece seem more valuable than it is. You want to know what to watch for.
Reputable jewelers exist. Disreputable ones also exist — and can look very similar. Understanding how common scams operate — what evidence is fabricated, what claims cannot be verified, and what pressure tactics are used — helps you recognize them before you become a victim.
Go to a reputable jeweler. Check reviews. You will be fine.
Decisions this guide supports:
Is your jewelry real? — Start with observation before testing.Choose a jeweler carefully — Ask the right questions before handing over your piece.Certificate guide — What certificates actually verify.For any significant transaction: verify independently. Look up certificate numbers online. Get a second opinion from a jeweler who is not involved in the sale. Photograph pieces before leaving them for repair. Ask for written documentation of claims. A legitimate seller welcomes verification. A scammer will pressure you to skip it.
Stone swapping occurs when a jeweler removes genuine stones from your piece and replaces them with lower-quality or synthetic stones. It is difficult to detect without documentation. Protect yourself by photographing your stones — including close-ups showing inclusions and characteristics — before leaving any piece for repair. A reputable jeweler will not object to this documentation.
Verify the report number on the laboratory official website. GIA, IGI, and other major labs maintain online databases. A forged certificate may have a real-looking number that does not appear in the database. If a seller refuses to provide the report number before purchase, consider it a red flag.
They can be — with precautions. Verify the seller history and return policy. Look for independent grading reports. Be skeptical of deals that seem too good. Understand that photographs can be manipulated and descriptions can be misleading. Bid what the piece is worth to you based on what you can verify — not what the seller claims.
An inflated appraisal states a replacement value far above what the piece would actually cost to replace — often 2-3× the realistic figure. This makes the buyer feel they are getting a great deal. The appraisal is real — the stated value is not. An independent appraiser who does not sell jewelry can provide an unbiased assessment. An appraisal from the seller is not independent.
