Most antique brooches are worth about $30-300. The bar brooches, sentimental pieces, seed pearl crescents and gold-front bars that fill inherited jewelry boxes were made in large numbers between 1860 and 1930, and they sell for their gold content plus a modest premium for design and condition. The pieces worth real money are a smaller group: Georgian and early Victorian gold with natural gems, signed Art Nouveau enamel, platinum and diamond Edwardian and Art Deco brooches, micromosaic and pietra dura from the Grand Tour period, and anything by a named house such as Cartier, Tiffany, Lalique, Boucheron or Castellani. Those run from about $500 to well into five figures, and the signature or the stones, not the age, is what carries the price.
Quick answer
- Common Victorian and Edwardian gold brooches sell for about $80-400 as of late 2026, driven mostly by gold weight at about $4,000 per ounce.
- Gold-front, gilt metal, pinchbeck and rolled gold pieces sell for about $20-120 on design alone.
- Signed, platinum, diamond-set or enamel pieces by a named maker reach $1,000-20,000 and more.
- The clasp, hinge and pin length date the piece; the marks give the metal; the stones and signature give the premium.
How to identify and value a brooch, step by step
- Turn it over and look at the catch. A plain C-shaped hook with no moving part is a C-clasp, standard before about 1900 and still used on cheap pieces into the 1920s. A trombone clasp, a small tube that pulls out to release the pin, is European and runs from about 1890 to the 1940s. A safety catch that rotates over the pin, the kind on modern brooches, was patented in the 1900s and common from about 1910 onward.
- Look at the hinge. A long tube hinge, the full width of a cylinder soldered to the back, is typical of pieces before about 1890. A small round hinge with a visible rivet is later.
- Measure the pin. On Victorian brooches the pin often extends well past the edge of the piece, because it was meant to go through heavy fabric and then be hooked back under the clasp. Pins that end at the edge of the brooch are later.
- Find the marks. Look on the back, the pin stem, the clasp and the edge. British gold is marked 9, 12, 15 or 18 with a crown and an assay office mark; 12ct and 15ct were used only from 1854 to 1932, which dates a piece on its own. Continental gold is marked 585, 750 or with a small animal head. American pieces read 10K, 14K or sometimes nothing at all before about 1906. Silver reads STERLING, 925 or carries a lion passant. Gold-filled pieces read 1/20 12K GF or similar. No mark at all is common on pieces before 1900 and does not mean base metal; a jeweler with XRF settles it in a minute. Our guide to how to read jewelry hallmarks decodes the symbols.
- Test the metal if unmarked. A magnet pulls base metal and some gilt pieces; gold and silver do not respond. Gold-front and rolled gold pieces show a yellow surface with a different color at worn edges and on the pin stem. Pinchbeck, a copper and zinc alloy used from about 1720 to the 1850s, looks like gold but is lighter and turns brassy at wear points. Our guide to gold-filled versus gold-plated covers what the layered pieces are worth.
- Identify the stones. Seed pearls, half pearls, garnets, amethysts, turquoise, coral and paste are the usual Victorian stones and carry little value beyond the design. Old mine and rose cut diamonds, natural sapphires, rubies and emeralds carry real value; check them with the loupe, and treat a brooch with a large colored stone as worth a lab report. Black stones are usually jet, French jet, which is black glass, or vulcanite, a hard rubber; jet is warm and light, glass cold and heavy. Coral and ivory pieces fall under CITES and US and EU trade rules, which restrict sale across borders and in some states; a dealer will tell you what applies.
- Look for a signature. A maker's name on the back, a small cartouche, or a registered number changes everything. Castellani, Giuliano, Lalique, Cartier, Tiffany, Boucheron, Murrle Bennett and Liberty are the names that push a brooch from gold value to collector value. Many are faked, so a signature is the start of a question, not the end.
- Weigh it and do the gold sum. Gold at about $4,000 per ounce as of late 2026 works out to about $75 per gram for 14K, $96 for 18K, $80 for 15K and $48 for 9K. A 4 gram 15ct Victorian bar brooch holds about $320 in gold, which is also roughly what a plain one sells for.
What antique brooches sell for
Prices are what honest pieces sell for at auction and on resale platforms as of late 2026, with gold at about $4,000 per ounce and silver at about $58 per ounce. Signed and gem-set pieces are priced by the individual piece and these are only starting points.
| Type | Era | Typical value, about | What drives it |
|---|---|---|---|
| Gold bar brooch, 9ct or 15ct, seed pearls or small garnet | 1880-1920 | $80-400 | Gold weight; most sell near melt plus a little |
| Gold-front or rolled gold bar or crescent | 1880-1920 | $20-80 | Design only; base core |

| Retro gold, rose gold, large scrolls, small rubies | 1935-1950 | $400-2,500 | Gold weight; 14K and 18K pieces heavy |
The first row is the honest center of the market. Most of what arrives in a box labeled grandmother's brooches is 9ct or 15ct British gold or 10K American gold, set with seed pearls or a garnet, and sells for gold weight plus about 20 to 50 percent. At current gold prices a tray of a dozen such pieces is often worth $1,500-3,000 in metal alone.
Dating by the back: a quick table
| Feature | Before 1880 | 1880-1910 | 1910-1940 | After 1940 |
|---|---|---|---|---|
| Catch | C-clasp, often large | C-clasp or trombone | Safety catch arrives, trombone in Europe | Rotating safety catch standard |
| Hinge | Long tube hinge | Tube or small round | Small round, riveted | Small round, machine made |
| Pin | Extends past the edge, thick | Extends slightly or ends at edge | Ends at edge | Ends at edge, thin |
| Metal marks | Often none; pinchbeck or unmarked gold | British crown marks, 9, 12, 15, 18; continental numbers | 9, 14K, 18K, 585, 750, GF | 925, 14K, 585, maker's mark |
| Stones | Paste, foiled garnets, seed pearls, flat-cut | Half pearls, garnets, turquoise, old cuts | Platinum settings, calibré cut | Synthetic stones common |
| Back finish | Hand-finished, closed backs behind stones | Open backs begin | Open galleries, pierced work | Cast, uniform |
No single feature dates a piece, because catches and pins were replaced when they broke. Two or three features that agree are a reliable date. The same back-of-the-piece reading is covered for rings in our guide to how to tell if a ring is antique.
Common mistakes: things that look like treasure
Sentimental Victorian pieces are the group most often overvalued. A hair-work brooch with a lock of hair behind glass is a touching object and sells for about $60-250, less if the hair is damaged or the glass is cracked. A gold-front bar brooch with a tiny diamond chip in the center is about $40-100. A large Bohemian garnet brooch looks like rubies and is set in gilt silver worth almost nothing beyond the design. Paste, leaded glass cut and foiled to imitate diamonds, is collected when the setting is 18th century silver, about $100-600 for good Georgian pieces, but later paste sells for $20-80.
The reverse happens too. Platinum-topped gold, which is a thin layer of platinum over gold used from about 1900 to 1920, looks like white metal and is sometimes sold as silver. Old mine cut diamonds look dull next to modern stones and are sometimes mistaken for paste; the loupe shows a small table, a high crown and a visible culet. Our guide to how to tell if a diamond is real covers the tests.
How WorthPic reads brooch photos
WorthPic runs on the newest and most capable AI model available, tuned for exactly this kind of identification. Photograph the front, the back with the catch and hinge in focus, any mark under good light and the stones close up, and it reads the catch type, the hinge, the pin length and the finish of the back against the eras those belong to, decodes the marks it can read, identifies the stones as far as a photo allows, and judges whether it is cast or hand-finished. From that it gives an honest value range built on gold weight when it can estimate it and on comparable sold pieces when the design or signature is what matters, and it says plainly when a detail is not visible, most often whether unmarked metal is gold, whether a colored stone is natural and whether a signature is genuine, and names the photo or the test that would settle it. It identifies and estimates. It never authenticates a signature or appraises for insurance; a jeweler with XRF for the metal, a gem lab for a significant stone and an auction house jewelry specialist for a signed piece are what settle the valuable cases.
What to photograph
- The front, flat on a plain background, in daylight.
- The whole back, in focus, so the catch, hinge and pin are visible together. This is the photo that dates it.
- Any mark, as close as the camera will focus, with the light raking across the surface.
- Each type of stone close up, with a loupe over the lens if you have one.
- The piece on a kitchen scale showing grams.
When to get it looked at in person
- A jeweler with an XRF analyzer reads the metal content of an unmarked piece in a minute, usually for little or nothing, and settles whether an old brooch is gold, gold-front or gilt.
- A gem lab such as GIA, AGL or SSEF for any colored stone or diamond that could be worth more than a few hundred dollars. A report on a natural sapphire or an old cut diamond changes the value of the brooch.
- An auction house jewelry specialist, at Bonhams, Sotheby's, Christie's, Skinner or a regional house, for anything signed, anything Georgian, anything in platinum with diamonds, and anything that might be by a named Art Nouveau maker. They give an estimate from photos.
- A costume jewelry specialist if the piece turns out to be base metal; Victorian and 1930s to 1950s signed costume brooches have their own market, covered in our guide to whether costume jewelry is worth anything.
