Everything you need before submitting.
Clear answers on photographs, outcomes, payment, certificates and privacy.
What photographs should I upload?
Include the full item plus close, sharp views of labels, stitching, hardware, logos, serial or date codes and any packaging or paperwork. Watch submissions should include the dial, case, caseback, crown, clasp, reference details and movement only where it can be photographed safely.
How long does a check take?
Timing depends on the item, the evidence supplied and whether additional photographs are needed. Your submission can only be completed once the visible evidence is sufficient for an opinion.
What result will I receive?
You receive an authentication outcome, a confidence percentage and an evidence summary. Authentic outcomes include a digital PDF certificate of authenticity.
Is the result guaranteed?
No remote photo review can offer an absolute guarantee. The result is an expert opinion based on the quality and completeness of the submitted images and information.
What happens if my photos are not clear enough?
More detailed images may be needed before the review can be completed. Use the photo guides to capture labels, hardware, construction and identifying details clearly.
Can you authenticate jewellery from photos?
ThreadCheck can assess branded jewellery from visible evidence such as maker marks, hallmarks, engravings, construction, settings and packaging. This is not metal-purity testing, gemstone identification or grading, valuation, or a substitute for an in-person jeweller or gem laboratory.
How are payments handled?
Payment is processed securely by Stripe. ThreadCheck does not store your card number.
How are my photos stored?
Photos are kept in private storage while the item is reviewed and deleted when the final decision is recorded. Essential order records may be retained for customer service, accounting and legal purposes.
