What this scam usually looks like

In this scam, a seller advertises gold, diamond, or gemstone jewellery as genuine and valuable, but the items are fake, plated, or far lower grade than claimed, sold at prices that seem like a bargain.

Marketplace scams target both buyers and sellers on platforms like Facebook Marketplace and classified listings. Fraudsters fake payments, send bogus "buyer protection" emails, push deals off-platform, or use overpayment tricks to make you ship goods or send money for nothing.

The single clearest warning sign to remember is this: Valuable-looking jewellery sold cheaply as genuine, with no independent certification. Get independent appraisal or certification before paying significant sums.
