Most cameos are worth about $30-300. The shell cameo of a woman in profile, carved in Torre del Greco near Naples and set in a 10K, 14K or gold-filled frame, was made by the hundred thousand from the 1850s through the 1980s, and a typical one sells for about $50-150 in a gold-filled frame and $150-400 in a 14K frame as of late 2026. The cameos worth real money are a smaller group: hardstone cameos cut in agate or sardonyx, signed shell cameos by named carvers, scenes with several figures rather than a single profile, and 18th and early 19th century pieces in gold frames by known workshops. Those run from about $500 to $10,000 and more, and the material, the carving and the frame together set the price.
Quick answer
- Shell cameo, gold-filled frame, single profile: about $50-150. Same in 14K gold: $150-400. Signed shell cameo, fine carving, 14K or 18K: $300-1,500.
- Hardstone cameo, agate or sardonyx, 19th century: $500-5,000; signed or museum quality: $5,000-50,000.
- Resin, plastic and molded glass cameos: $5-40.
- Backlight settles shell from stone; a hot needle or a loupe settles resin; the frame marks give the gold.
How to identify and value a cameo, step by step
- Hold it against the light. Shell cameos, cut from the helmet shell or the queen conch, are thin, usually one to three millimeters, and glow pink-orange or cream when a lamp is behind them. The back is gently concave, following the curve of the shell. Hardstone cameos in agate, sardonyx or onyx stay dark and opaque, and the back is flat. Lava cameos from Pompeii are matte grey, brown or olive and opaque. Resin usually passes a little light but evenly, with no growth lines.
- Look at the back under a loupe. Shell shows fine curved lines, like a fingerprint, following the shell's growth, and a slightly uneven surface. Stone shows a polished or dull flat back with no lines. Resin and plastic show a perfectly uniform surface, sometimes a mold seam at the edge, and tiny bubbles. Glass shows bubbles and a slightly rounded edge where it was pressed.
- Test the temperature and weight. Stone is cold and dense; a hardstone cameo of brooch size weighs noticeably more than a shell one. Shell is cool and light. Resin and plastic warm quickly in the hand. A hot needle touched to the back edge of a plastic cameo melts in and smells; it does nothing to shell or stone.
- Look at the carving. Hand-carved shell shows tool marks under the loupe, undercutting behind the hair and the chin, and fine detail in the curls and the drapery. Molded resin shows soft, rounded detail, identical pieces on every example, and no undercutting. Ultrasonic-carved shell, common since the 1970s, is sharp but mechanical, with the same face repeated.
- Read the profile. The subject dates the piece. Classical gods, mythological scenes and Roman emperors are 1800-1860. A woman with a Roman nose, a strong chin and an elaborate upswept hairstyle is 1860-1900. The pretty girl with an upturned nose, a soft chin and loose curls is 1900-1950. A woman wearing a tiny diamond necklace or earrings, called a cameo habillé, is usually 1920-1970. Scenes with several figures, such as the Three Graces, Rebecca at the Well or a chariot, carry more value than a single profile in every era.
- Read the frame. Marks on the back or the pin stem give the metal: 10K, 14K, 18K, 585, 750, 9ct, GF, 1/20 12K, STERLING or 800 for continental silver. A gold frame at about $4,000 per ounce adds real money: a 14K frame of 5 grams holds about $375 in gold alone. The catch and hinge date the frame; a C-clasp and tube hinge point to before 1900, a safety catch to after 1910. Our guide to how to read jewelry hallmarks covers the marks.
- Check for a signature. Signed cameos carry the carver's name on the back, the edge or sometimes on the front near the shoulder. Giovanni Noto, Saulini, Girometti and Pistrucci are the 19th century names; many 20th century Torre del Greco carvers also signed. A signature is worth checking against reference books, because carvers' names are added to ordinary pieces.
- Price it against sold comparables. Search sold listings for the material, size, subject and frame karat.
What cameos sell for
Prices below are what honest pieces in good condition sell for on resale platforms and at auction as of late 2026, with gold at about $4,000 per ounce. Cracks, chips to the profile and replaced frames cut these figures sharply.
| Type | Era | Typical value, about | Notes |
|---|---|---|---|
| Shell cameo, single profile, gold-filled or gilt frame | 1900-1980 | $30-120 | The most common cameo; frame adds nothing |
| Shell cameo, single profile, 10K or 14K frame | 1900-1980 | $120-400 | Gold weight is most of it |
| Shell cameo, habillé with diamond chips, 14K | 1920-1970 | $150-500 | Diamond chips are tiny; the frame carries it |
| Shell cameo, fine Victorian carving, 15ct or 18K frame | 1860-1900 | $300-1,200 | Quality of the carving and the frame |
| Shell cameo, multi-figure scene, hand carved | 1850-1950 | $300-2,000 | Figures, depth and condition |
| Shell cameo, signed by a known carver | 1850-1980 | $300-3,000 | Signature must match references |
| Lava cameo, Pompeii souvenir, in gilt or gold | 1830-1880 | $60-500 | Grey and brown; bracelets with several higher |
| Hardstone cameo, agate or sardonyx, unsigned | 1800-1900 | $500-5,000 | Depth of the layers and the carving |
| Hardstone cameo, signed or attributed, gold mount | 1780-1880 | $3,000-50,000+ | Auction territory; provenance matters |
| Coral cameo, Mediterranean | 1850-1950 | $150-1,000 | CITES and EU and US trade rules affect sale and export |
| Ivory cameo | 1800-1920 | $50-400 | US and EU rules restrict sale; many venues refuse it |
| Wedgwood jasperware cameo, silver or gilt | 1780 onward | $40-300 | Ceramic, not carved; 18th century pieces higher |
| Molded glass or paste cameo | 1880-1960 | $20-100 | Pressed, bubbles, uniform |
| Resin or plastic cameo, any frame | 1950 onward | $5-40 | Mass produced; frame is usually base metal |
The second row is the center of the market. A 14K framed shell cameo of a single profile, which is what most inherited cameos are, sells for the gold in the frame plus about $50-150 for the carving. Nobody should expect more unless the carving is exceptional, the piece is signed or the frame is heavy.

Shell cameos are sometimes sold as hardstone by people who see the word sardonyx, which is the name of a shell variety as well as the stone; the sardonyx shell is the brown and white helmet shell, and it is still shell. The backlight test ends the confusion.
Legal notes on coral and ivory
Coral cameos, mostly in Mediterranean red or pink coral, were carved alongside shell in Naples. Many coral species are listed under CITES, and the EU and several US states restrict sale and export of coral jewelry; auction houses and online platforms often decline it or require documentation of age. Ivory cameos, which are rarer, fall under stricter US federal and state rules and the EU ivory regulation, with narrow exemptions for antiques and requirements that are hard to meet for a small piece. This is not legal advice; a dealer or auction house in your state or country will tell you what applies, and it is worth asking before listing a coral or ivory piece anywhere.
How WorthPic reads cameo photos
WorthPic runs on the newest and most capable AI model available, tuned for exactly this kind of identification. Upload the front, the back, the cameo held against a lamp, any frame marks and the catch, and it reads the material from the translucency and the back, judges the carving for undercutting and tool marks against molded detail, places the profile in its era by the nose, the hair and the dress, decodes the frame marks and estimates the gold weight, and looks for a signature. From that it gives an honest value range built on the frame metal and on comparable sold cameos of that material and quality, and it says plainly when something cannot be judged from the photos, most often whether a signature is genuine, whether a hardstone cameo is 19th century or a modern copy, and whether a coral piece can legally be sold where you are, and names the photo or the person who would settle it. It identifies and estimates. It never authenticates a carver's signature or appraises for insurance; an auction house jewelry specialist for a signed or hardstone piece and a jeweler with XRF for the frame are what settle the valuable cases.
Common mistakes
- Calling every cameo antique. Most shell cameos in circulation are 1950s to 1980s tourist and gift pieces, and that is fine, but they sell for $50-400, not thousands.
- Mistaking sardonyx shell for hardstone. Backlight it; shell glows.
- Ignoring a crack. A hairline crack through a shell cameo, visible when backlit, takes off half the value or more.
- Pricing the frame as the cameo. A heavy 18K frame on an ordinary cameo is worth its gold; the carving adds little.
- Trusting a signature. Names are added to ordinary cameos; a signature must match the carver's known style and period.
- Listing coral or ivory without checking the rules. Platforms remove such listings and some sales are illegal.
What to photograph
- The front, flat on a plain background, in daylight.
- The cameo held against a lamp or a window, so the translucency and any cracks show. This is the photo that settles shell from stone and resin.
- The back, close and in focus, including the catch and hinge.
- Any mark on the frame or the pin stem, with raking light.
- The profile at an angle, so the depth of the carving and any undercutting is visible.
- A ruler beside it, and the piece on a kitchen scale.
When to get it looked at in person
- An auction house jewelry specialist at Bonhams, Sotheby's, Christie's, Skinner or a regional house, for any hardstone cameo, any signed cameo, any multi-figure scene in a gold frame and anything that might be Georgian. They give an estimate from photos and know the carvers.
- A jeweler with an XRF analyzer to confirm the frame metal in a minute if it is unmarked.
- A gem lab such as GIA if a cameo is set with real diamonds or colored stones of any size.
- A dealer in antique jewelry who handles cameos regularly, for a written opinion on a signed piece before selling it.
