What Is My Antique Jewelry Worth?
Every piece of jewelry has four different values at the same time, and most disappointment comes from being quoted one and expecting another. Here is what actually drives the number, and how to find out where your piece sits before anyone makes you an offer.
The first thing to understand is that there is no single number. The same brooch has four values simultaneously, and they can differ by a factor of ten.
| Which value | What it means | Typically |
|---|---|---|
| Melt or scrap | The raw metal if the object were destroyed | The floor |
| Trade or wholesale | What a dealer will pay you today, cash | 40 to 60 per cent of retail |
| Auction estimate | What it might fetch at open sale, before fees | Variable, and net of 15 to 30 per cent commission |
| Retail replacement | What it would cost to buy an equivalent from a shop | The ceiling, and what insurers use |
An insurance valuation is not what anyone will pay you. It is the highest of the four by design, because its purpose is to fund a replacement at retail. People discover this at the worst possible moment.
The six things that actually drive the number
1. What it is made of, and how much of it there is
The floor under everything. Work it out with the gold calculator so that you know the number nobody can go below. If a buyer offers less than melt for an intact antique piece, the conversation is over.
2. The stones
Usually the largest single factor when they are significant. Two things dominate: size and whether they are original to the piece. A ring with a two carat old European cut diamond is a stone with a mount attached, and the mount is almost incidental to the price.
Old cuts have appreciated substantially since the mid 2010s, because supply is fixed and demand has risen. A good old mine or old European cut now frequently sells above a modern brilliant of the same weight and grade.
Natural pearls versus cultured is the largest single valuation gap in antique jewelry, and it can only be settled by X-ray at a laboratory. A seller who states natural without a report is stating an opinion.
3. Workmanship
The part a photograph hides. Hand-piercing, calibre-cut stones fitted edge to edge, millegrain worked with a wheel rather than cast, a back finished as carefully as the front. These separate a good period piece from an ordinary one of the same date and metal, and they are the reason two apparently similar Edwardian brooches can differ fourfold.
4. Maker
Binary in effect. A signature from Cartier, Van Cleef and Arpels, Boucheron, Faberge, Lalique, Georg Jensen or Tiffany moves a piece into a separate market. Everything else, however well made, is judged on its merits.
Signatures on the important houses are also the most forged marks in the trade, so a signature that would multiply the value should be authenticated formally rather than accepted.
5. Condition and originality
Condition matters more in antique jewelry than most people expect, because restoration is expensive and rarely returns its cost.
- Unaltered is worth a premium. Converted, re-stoned and resized pieces are worth less, though conversion is so common in early work that it is not disqualifying.
- Original stones matter. A replaced modern brilliant in a Victorian mount reduces the piece to its metal and its design.
- Enamel damage is close to unrepairable. Chipped enamel is a permanent deduction.
- Foil damage on Georgian closed-back pieces, usually caused by water, kills the stone's appearance and cannot be reversed without resetting.
- Wear to hallmarks costs real money by making the piece harder to date and attribute.
6. Whether anyone currently wants it
The factor nobody lists and everyone is subject to. Art Deco has been in demand for two decades. Victorian mourning jewelry is a specialist taste with a narrow market. Large Victorian gold lockets, once the standard inheritance, are worth little more than their metal because supply enormously exceeds demand.
Age does not create demand. It only limits supply.
How to get a realistic figure
Step one: date it and identify it. You cannot value what you cannot describe. Work through how to date antique jewelry, read the marks with the decoder, and identify the cut of any significant stones.
Step two: find the floor. Weigh the piece, deduct roughly for stones, and calculate the metal.
Step three: find comparables, and find the right ones. Search completed sales rather than asking prices, since asking prices include everything nobody bought. Auction results are public and are the closest thing to a real market record. Compare like with like: same era, same metal, same stone quality, same condition.
Step four: get more than one opinion, and understand what each one is for. A dealer's offer is a trade price and will be well below retail, which is not dishonesty but the cost of them carrying the piece. An auction estimate is a guess at a hammer price before fees. An insurance valuation is retail replacement. Ask which one you are being given.
When it is worth paying for a formal valuation
A written valuation from a qualified appraiser costs money and is worth it in four situations: insurance on anything significant, probate and division of an estate, divorce, and any single piece you believe is worth more than a few thousand.
For everything else, two or three dealer opinions plus auction comparables will get you close enough to make a sensible decision, at no cost.
Where the money actually goes when you sell
| Route | You typically receive | Speed | Best for |
|---|---|---|---|
| Scrap or gold buyer | Below melt, 70 to 90 per cent of spot | Immediate | Broken, plated or damaged pieces with no design value |
| Dealer, outright sale | 40 to 60 per cent of retail | Days | Anything a specialist recognises |
| Auction | Hammer price less 15 to 30 per cent | Weeks to months | Signed, rare or high value pieces |
| Consignment with a dealer | Retail less 20 to 40 per cent | Months | Good pieces where you can wait |
| Private sale or marketplace | Closest to retail | Slowest, and the work is yours | Recognisable, describable pieces |
Frequently asked questions
How much is my antique jewelry worth?
It depends on metal content, the stones, workmanship, maker, condition and current demand, in roughly that order of variability. Start by calculating the melt value as a floor, then compare completed auction sales of similar pieces, then get two or three dealer opinions.
Is antique jewelry worth more than the gold in it?
Usually, for anything made before about 1940 or anything with good workmanship or original stones. Not always: mass-produced late Victorian hollow gold pieces in poor condition are frequently worth little more than their metal.
What is the difference between an appraisal and an offer?
An appraisal is a professional opinion of value for a stated purpose, most often insurance replacement at retail. An offer is what a specific buyer will pay today, which is a trade price and much lower. They are not comparable numbers.
Should I clean antique jewelry before selling it?
Light surface dust, yes. Anything more, no. Over-cleaning removes patina, can strip bloomed gold finishes, damages enamel and destroys the foil behind stones in closed-back settings. Dealers expect and prefer honest dirt.
Where can I get antique jewelry valued for free?
Auction houses give free verbal estimates in the hope of consigning the piece, which is the most useful free opinion available. Dealers will make offers, which is a different number. Free online valuations are marketing rather than appraisal.
Does a hallmark increase value?
Indirectly. A clear hallmark makes a piece easier to date, attribute and trust, and that certainty translates into price. The mark itself adds nothing; what it removes is doubt.
