What makes jewelry and watches valuable
Jewelry and watches are valued on two levels: the material and the maker. Gold, silver and platinum carry value from the metal itself, which is why reading karat, fineness and hallmark stamps comes first. Watches and signed jewelry add a second layer: the brand, the reference or model, the movement, and the box and papers. Plated, filled and costume pieces can still sell, but they are priced very differently from solid precious metal. Because these items are small and can be valuable, they are also often faked, so careful checks matter.
What to check first
- Find the stamps: use a magnifier to read karat or fineness marks, hallmarks, maker's marks and serial or reference numbers.
- Tell solid from plated: look for plating marks and for worn areas where a different metal shows through.
- Check watches: does it run, and are the crystal, crown, bracelet and clasp intact and original?
- Keep the paperwork: boxes, papers, receipts and spare links belong with the item.
How to use these guides
Start with the jewelry guide for stamps and safe checks, the silver marks guide for sterling and hallmarks, or the watch guide for reference numbers and movements. The designer bags guide covers accessories where authenticity comes first, and the scams guide helps you sell valuable pieces safely.
Where WorthAI fits
Scan the piece to identify the likely type, brand or model, then check the estimated worth with a range, the suggested asking price and the listings behind it. Add a sharp photo of the stamp, dial or case back if WorthAI asks for more detail. A photo cannot test metal purity, confirm gemstones or authenticate a watch, so use a jeweler, appraiser or watchmaker for valuable pieces. The resale profit calculator shows what you keep after fees and shipping, and the listing title builder helps you lead with brand, model and material.

Frequently asked questions
How can I tell if my jewelry is real gold or silver?
Look for karat or fineness stamps such as 14K, 18K or 925, or a hallmark, and check for plating marks or wear that shows another metal. A stamp is a clue, not proof, so ask a jeweler to test valuable pieces.
Do I need an appraisal to sell jewelry or a watch?
Not for everyday pieces. For gold, platinum, gemstones and valuable watches, an appraisal or a watchmaker's check helps you price fairly and answer buyers' questions.
Do the box and papers matter when selling a watch?
Yes. The original box, papers, receipts and spare links help buyers trust the watch and can make it easier to sell. Photograph them together with the watch.
