What a jewelry identifier app should tell you

The useful answer names the piece, the likely metal and stones, the period or style, and any hallmark that narrows it down. Hallmarks and maker's marks are the details a photo most often misses, so an app that asks for close-ups is worth more than one that stops at the first photo.

How it handles value

Most of these apps offer a value estimate. Metal weight, stone quality and provenance decide the real price, so treat any figure as a starting point, and have anything valuable checked by a qualified jeweller or appraiser.

Privacy, and what happens after the scan

A good app keeps a record of every piece you scan without asking for an email address. Check whether an app needs an account, and whether your finds are stored on your phone or on the developer's servers.
