Jewelry value checker & identifier
Point your camera at any piece and Minti reads the metal, karat marks, hallmarks, and style to identify vintage, costume, and fine jewelry, then shows a market-based value estimate from recent eBay sold listings. Identify it, track it, and sell it, all in one app.
How much is your jewelry worth?
Jewelry value moves with the market, and old receipts rarely reflect what a piece sells for today. Minti gives you a market-based estimate grounded in recent eBay sold listings, so a vintage brooch, a signed designer bracelet, or a 14K gold chain each get a value drawn from comparable real sales rather than a guess.
- Market-based value estimate from recent eBay sold comps
- Honest by design: gemstone and fine jewelry value often needs a professional appraisal, so Minti gives a market estimate from comparable sales, not a formal appraisal
- Price history across 7-day, 1-month, 6-month, and 1-year windows
Identify any piece in seconds
Not sure what you're holding? Minti's AI reads the piece and any marks to identify the metal and karat, hallmarks and maker's marks, and the style or era, so you can tell vintage, costume, and fine jewelry apart. Gemstones affect value and may need a professional appraisal to confirm.
- Reads karat and purity stamps like 14K, 18K, 925, and 750
- Recognizes hallmarks, maker's marks, and signed designer pieces
- Auto-fills metal, style, era, and condition so your entry stays clean
What drives jewelry value
A few factors do most of the work when it comes to what a piece is worth. Minti surfaces the ones a photo can read, and flags where a professional appraisal is the right next step.
- Metal content: the karat and purity of gold, silver, or platinum sets a real floor for value
- Maker and brand: signed pieces from known makers and designers carry a premium over unsigned work
- Gemstones: diamonds and colored stones can drive value sharply, and often need an appraisal to confirm quality and treatment
- Age and condition: era, wear, repairs, and originality all shift what a buyer will pay
Organize your jewelry collection
Keep your pieces in sets and folders that mirror how you actually collect. Every item carries its images, metal, style, and current value estimate, and your portfolio total updates as the market moves, so you always know what your jewelry box is worth.

Jewelry FAQ
How do I find out what my jewelry is worth?
Scan the piece with Minti. The AI reads the metal, karat marks, hallmarks, and any maker's marks to identify what you have, then gives a market-based value estimate from recent eBay sold listings so you see what comparable pieces are actually selling for. For gemstone and fine jewelry, this is a market estimate from comparable sales, not a formal appraisal.
Can Minti identify the metal, hallmarks, and maker?
Yes. Minti reads karat and purity stamps like 14K, 18K, 925, and 750, identifies hallmarks and maker's marks, and recognizes the style and era of a piece to tell vintage, costume, and fine jewelry apart. Clear photos of the marks give the best results.
Do I still need a professional appraisal?
Often yes. Gemstone and fine jewelry value depends on details a photo cannot confirm, such as diamond grading, gemstone treatment, and precise metal weight, so a professional appraisal is the right call for insurance or high-value pieces. Minti gives you a fast market-based estimate from comparable eBay sold listings to help you decide what is worth appraising.
Is Minti free to use?
Yes. Minti is free to download and includes a monthly allowance of AI scans, plus organizing, value tracking, and marketplace access. Paid tiers raise the scan and storage limits for larger collections.
How do I sell jewelry on Minti?
List any piece as a fixed-price Buy It Now or a live auction, receive offers from buyers, and accept secure payment through Stripe. Minti generates a pre-paid shipping label and holds funds until the buyer confirms delivery.
