Jewelry & Precious Metals
Rules for selling jewelry and precious metals including FTC jewelry guides, karat/carat disclosures, gemstone authenticity, and hallmarking requirements.
What this covers
FTC jewelry guides require that gold karat (14K, 18K), silver purity (925), and platinum content all be disclosed accurately in listings — overstating metal quality is both an FTC violation and grounds for removal. Gemstone treatments such as heat enhancement, fracture filling, or dyeing must be disclosed; presenting a treated stone as natural is fraud, not just a listing error. Lab-created diamonds and gemstones must be clearly labeled as synthetic or lab-created and cannot be described or priced in a way that implies natural origin.
Start with the current guidance below, then use recent updates for context on what shifted.
