How do I identify a piece of jewelry from a photo?
Centre the piece in the frame and tap the shutter, or pick an image from your photo library. Lustre sends the photo for AI analysis and returns the piece, its category and era, its stones, its metal and hallmark, and an estimated value range.
Is Lustre a certified appraisal?
No. Identifications and value estimates are AI-generated estimates for informational and entertainment purposes only. Lustre is not a certified gemological laboratory or appraisal service, and its results are not a certified appraisal, valuation, or authentication, nor financial, investment, insurance, or resale advice. Never buy, sell, insure, declare, or transact based solely on the app's output. Obtain a qualified independent appraisal first.
What does a result actually tell me?
A name and category, an era, a confidence percentage, the metal, the setting and any hallmark read from the photo, each gemstone with its estimated carat, colour, clarity and cut, and a full report with three value figures, a breakdown of what drives them, and recent auction comparables.
How accurate are the value estimates?
Every result carries a confidence percentage, and the value is shown as a range rather than a single number. A photograph cannot verify metal purity, gemstone treatments, synthetic versus natural stones, or internal characteristics, so treat the estimate as a well-informed starting point and have anything that matters appraised in person.
Does Lustre keep my photos?
No. Photos travel over HTTPS to our backend, which passes them to Google Gemini for analysis and returns the result. They are processed transiently and are not retained by us afterwards. The copy saved with a piece stays on your device.
What happens to a piece after I identify it?
Save it and it becomes an entry in your Vault with your own photo, its category, its estimated value, and the date. The Vault totals what you have appraised, filters by type or favourites, and keeps the full report a tap away.
