Most jewelry identifier apps take a photo and give you back a name and a price. They differ in what they check before they give you that price, and in how they charge for it. Here are six of them side by side.
How we compared: we read each app's US App Store listing and its list of in-app purchases on November 3, 2026. A feature a listing does not mention may still be in the app, so read a blank as "not in the listing", not as "missing". GemstoneAI is our app. We describe it from how it works, and the full method is on how GemstoneAI values jewelry.

As shown in each listing's in-app purchases on November 3, 2026. Apple shows up to ten per app and developers often test several prices at once, so the price you are offered can differ. A weekly plan at $3.49 to $4.99 works out to about $15 to $22 a month.
14K, 585 or 925 tells you the metal, and GP or HGE means plated. See every jewelry stamp.Photograph a ring, necklace or loose stone. GemstoneAI identifies it, reads the stamp and gives a first-read value with similar items for sale. Your first scan is free.

It depends on what you need. Most apps name jewelry from a photo. For a value you can act on, choose one that shows how it got there: the stamp it read, the metal at the day's price, similar items for sale, and what a photo cannot confirm. For insurance or a sale you still need a signed appraisal.
They give a first read from photos, not an appraisal. A photo cannot weigh a stone, measure it or prove it natural, so treat any app's value as a starting point and get an appraisal for anything you plan to insure or sell.
Most apps charge after a few free scans or a short trial. Google Lens is free and shows similar items for sale. GemstoneAI's first scans are free.
