How to Identify a Necklace from a Photo
Yes — you can identify a necklace from a photo. The clasp carries the metal stamp, the links reveal the chain type, and any pendant names the rest. One photo of the whole piece plus a close-up of the clasp is enough to tell what the necklace is and roughly what it's worth.

Can you identify a necklace from a photo?
Yes. A necklace gives you three signals in a picture: the stamp near the clasp (metal and purity), the chain type from the link pattern, and any pendant or stone. Together they identify the piece and its rough value. For pieces other than necklaces, see the broader guide to identifying jewelry from a photo.
Where the hallmark is on a necklace
Unlike a ring (stamped inside the band), a necklace is stamped near the clasp: on the clasp body, on a small flat tag soldered beside it, or on the spring ring. Photograph that spot closely — it's the most informative part of the piece.
Identify the chain type
The link pattern names the chain and hints at how much metal it holds:
| Chain | Link pattern |
|---|---|
| Cable | Uniform round or oval links |
| Figaro | Repeating long-then-short links |
| Curb | Flattened, interlocking links that lie flat |
| Rope | Links twisted into a spiral |
| Box | Square links forming a smooth cube chain |
| Snake / Herringbone | Smooth tubular, or flat parallel rows |
Identify the clasp
The clasp dates and grades a necklace. Lobster and spring-ring clasps are the modern default; a box clasp (a tab that clicks into a box, often with a safety) is common on older and higher-end pieces; a toggle (bar through a ring) is decorative. A handmade or unusual clasp often signals an antique piece.
Solid gold vs. gold-filled vs. plated
Necklaces are sold in every grade, so the clasp stamp matters most. Look it up in the hallmark directory:
- Solid gold — 750 (18K), 585 (14K), or 417 (10K).
- Sterling silver — 925.
- Gold-filled — “GF” or “1/20 12K GF”: a thick bonded gold layer, modest value.
- Plated — GEP, HGE, or “GP”: a thin electroplate over base metal, little melt value.
Identify the pendant or stone
If the necklace has a pendant, read its stone by color, cut, and luster — the gemstone reference covers the traits that separate, say, a diamond from cubic zirconia, or amethyst from glass. A stamped pendant may carry its own metal mark, too.
What's the necklace worth?
For a solid-metal chain, start with the melt value:
metal value = weight (g) × purity × live price per gram
Check today's gold and silver prices and convert the stamp with the karat reference. Gold-filled and plated chains have little melt value — their worth is mostly design and brand. The app estimates the full range from a single photo.
* Frequently asked
FAQ
- Q. Can I identify a necklace from a picture?
- A. Yes. A photo of the whole necklace plus a close-up of the clasp identifies most pieces — the clasp area carries the metal stamp, the links reveal the chain type, and any pendant or stone names the rest. A photo won't assay the metal, but it tells you the chain style, the likely metal, and whether it's solid or plated.
- Q. Where is the hallmark on a necklace?
- A. On a necklace the stamp is almost always near the clasp — on the clasp itself, on a small flat tag soldered beside it, or on the spring ring or jump ring. Photograph that area closely; that's where you'll find marks like 925, 750, 585, or GF.
- Q. How do I identify a gold chain type?
- A. Match the link pattern: cable (uniform round/oval links), figaro (repeating long-then-short links), curb (flattened interlocking links), rope (twisted spiral), box (square links), snake (smooth tubular), and herringbone (flat parallel rows). The chain type affects both style and how much metal the necklace contains.
- Q. Is my necklace real gold or gold-plated?
- A. Look at the clasp stamp. 750, 585, or 417 mean solid gold; GF or 1/20 12K GF means gold-filled (a thick bonded layer); GEP, HGE, or GP mean a thin electroplate over base metal. Solid-gold chains feel heavier for their size and show no wear-through at high-friction spots.
- Q. Is there a free necklace identifier?
- A. Yes. The Jewelry Identifier app reads a necklace photo and returns the metal, chain type, any gemstone, and an estimated value range — the first three scans are free, no account required. You can also look up any clasp stamp by text on identifyjewelry.app.
