In Brief

  • Autumn changes the conditions a piece of jewellery has to survive (wool, scarves, early dark) far more than it changes what is fashionable.
  • The clocks go back on Sunday 25 October 2026, and London's sunset falls from 5.52pm to 4.50pm overnight.
  • Buy for the coat: an antique brooch, a signet ring, a chain long enough to sit on knitwear, the season's stones, small earrings and pearls.
  • Gold over 1 gram sold in the UK needs three hallmark symbols. A bare 375 stamp is not a hallmark.
  • If a ring snags on knitwear, ask a jeweller to re-finish or re-tip the claws before you replace it.

Every October, a ring of mine pulls a thread from a jumper. It is always the same ring and always the same jumper, and I have stopped blaming the jumper. The ring has pointed claws and sits high off the finger, which was fine all summer on bare hands and linen sleeves. Then the temperature drops, the good brown coat comes out of the wardrobe, and everything I own is tested against wool, leather and a sky that gives up before I have finished my afternoon coffee.

That test is the real subject of autumn jewellery. A season changes the conditions a piece has to work in long before it changes anything in a shop window, and in London those conditions are entirely predictable. The clocks go back on Sunday 25 October 2026, and on that evening sunset arrives at 4.50pm, down from 5.52pm the day before. It is the sort of number I would print on the door of every jeweller in Hatton Garden.

This is the autumn jewellery edit I would hand a friend with one free evening and one budget: what changes when the light goes and the layers arrive, six pieces ranked by how hard I would defend each purchase to my bank, and the checks that stop you buying the wrong version of any of them.

What changes when the clocks go back

After the change, most weekday evenings belong to lamplight and low sun, and a piece has to look good in that light or it has no business being worn. I find that yellow gold does something warm and useful in a London interior in November, while pale stones in pale metal go flat. That is a prejudice, and it is mine, and I will defend it.

The practical consequence is that structure starts to matter more than sparkle. Nobody sees brilliance at a bus stop at ten to five. What you notice is whether the brooch sits properly on the coat, whether an earring has tangled in a scarf, and whether the ring has just taken a chunk out of a sleeve.

What changes when the coat comes out

A claw-set ring is a small collection of metal hooks held at exactly the height of a knitted cuff. Alan Bick, the jeweller, notes that a bezel's smooth surface is less likely to catch on knitwear, and that a claw which has worn down or lifted should be looked at promptly. Lily Dia Jewellery locates the problem in the finish of the claw tips: sharp or unfinished tips are the usual reason a ring catches, and the fix is a reshape and polish at the bench. Claws also wear on a schedule, and Smith Green Jewellers puts re-tipping at every 5–10 years depending on use.

So the first autumn job is a trip to the bench, and a new ring can wait. A jeweller can re-finish or re-tip the claws on the ring you already own. Replacing it gets you a fresh set of the same hooks. My Bayswater has been mended twice and I have never regretted either repair.

The necklace is the second casualty. The trade's standard lengths run: choker 14–16 inches, princess 17–19, matinee 20–24 and opera 28–36. A princess sits just below the collarbone, which is too short for knitwear: a crew neck needs at least 20 inches, ideally 20–22, for the chain to hang below the fabric, and a turtleneck needs 22 inches or more to clear the collar. Autumn's necklace is a length before it is a design, so buy the length first.

The edit, ranked

Ranked by how hard I would defend the purchase to my bank, which has views. Each entry ends with a verdict on my usual scale: is it worth the mortgage payment?

1. The antique brooch

A brooch is the only piece of jewellery designed for the garment this season is about. It goes on a lapel, a scarf or the shoulder of the good coat, it stays clear of cuffs, and it never has to negotiate a glove.

Turn it over before you fall for the front. An open C-shaped catch points towards older construction, but a C-catch alone does not make a brooch Victorian, because simple catches stayed in use and later pieces copy earlier ones. Treat the clasp as one piece of evidence and keep looking at the hinge, the pin and how the fittings are attached.

Saturday is the day to look. Portobello Road Market has its antiques arcades open on Saturdays, the only day all five of its sections trade, and it is a market where reproduction and new goods are stocked among the old. The back of the piece is where you do your arguing.

If Saturday is impossible, Grays at 58 Davies Street holds nearly 100 specialist dealers, and Visit London lists it as open Monday to Friday, 10am to 6pm (confirm before you travel, as some listings also show Saturday hours). For a dealer who will talk you through a piece before you commit, The Antique Jewellery Company sells online and from a Mayfair townhouse by appointment, and its founder, Olly Gerrish, began dealing at Portobello Market around 1973. Ask for a photograph of the back before you book.

Verdict: worth the mortgage payment, and the only entry here I would buy before a new coat.

2. The signet ring

A signet has no claws, no height and nothing for a cuff to catch, which makes it the natural ring for the season. The full argument is in The Signet Ring Edit; the autumn version is simply that it survives wool.

The buying check is the hallmark. Gold over 1 gram must be hallmarked to be sold as gold in the UK, subject to the exemptions in the Hallmarking Act 1973, and a full hallmark has three compulsory symbols: a sponsor's mark of at least two letters, a fineness mark, and an Assay Office mark (London, Birmingham, Sheffield or Edinburgh). The fineness number tells you the metal: 375 is 9ct, 585 is 14ct and 750 is 18ct.

Here is the part sellers rarely volunteer. A plain 375 or 750 stamp is a manufacturer's mark, and without the sponsor's and Assay Office marks it is not a hallmark, however official it looks. A seller who cannot show you all three marks on a signet over that weight needs to explain why. For the question of which gold to buy, 9ct vs 18ct vs 22ct settles it.

For a signet with a pedigree, Signets & Cyphers is a small London workshop, in business for over 30 years, whose rings follow a shape it traces to Victorian dies of 1860, drop-hammer stamped and seal-engraved by hand. It is bespoke, so expect a conversation before a price. For a ready-to-order 9ct oval at a lower price, Wild Fawn makes an initial signet in its London studio, listed at £420 when I looked. Wild Fawn states that its pieces are hallmarked where weight thresholds apply, so ask the weight, and ask whether the ring carries a full hallmark, before you assume it does.

Verdict: worth the mortgage payment, in 9ct, with the marks or a good reason for their absence.

3. The chain that sits on the knit

Length is the purchase. A matinee chain at 20–24 inches, or an opera chain at 28–36, sits on top of knitwear and stays visible. A 16-inch chain disappears under the first jumper you own. I would take a plain 24-inch chain over an elaborate 16-inch one every October.

A pendant is worth adding only after you have tried it on over the actual wool you will wear it with. The weight of a pendant changes where the chain falls, and the shop mirror does not know what you are wearing.

Maya Magal makes solid gold chains, including 9ct, in its London workshops, and offers a free clean and inspection at its King's Cross and Islington shops. Its chains have hollow links, which the brand describes as the choice that keeps them light and accessibly priced, so ask what a repair costs before you buy. For an antique chain or a locket, The Antique Jewellery Company lists both.

Verdict: worth the mortgage payment for a plain chain. Wait on the pendant.

4. The season's stones

The birthstone calendar is marketing, and useful marketing is still useful. On the modern list, September is sapphire, October is opal and tourmaline, and November is topaz and citrine. The Sapphire Buying Guide covers the first, and buying guides for opal and garnet, the two that suit this light best, follow in October.

Two cautions. Opal sits at 5.5–6.5 on the Mohs scale, which makes it a stone for earrings and pendants and a poor choice for a ring that lives against wool, pockets and door handles. And most citrine is produced by heating amethyst, which is a fair reason to pay quartz prices for it and no more. Tourmaline comes in enough colours that you should see the actual stone before you commit. For the folklore that attaches to all of them, Grimoire keeps the crystal lore.

For colour-led fine jewellery, Kiki McDonough was founded in London in 1985 and works in citrine, with fire opal and green tourmaline among its rarer stones, from a shop off Sloane Square. Its earrings are set in 18ct gold, so the price tag will have views of its own. Treat it as a case for wanting.

Verdict: worth it in earrings and pendants. Citrine only at citrine prices.

5. Earrings that clear a scarf

Scarves are where big drops go to die. I find that a stud or a small hoop survives a scarf, a collar and a wool hat, and a long drop survives none of them. If hoops are your answer, The Best Gold Hoop Earrings at Every Price Point has the case.

Alex Monroe makes studs in sterling silver, gold-plated silver and solid 18ct gold, and its London boutiques take repairs, which is why it earns a place on a list built around the Bayswater principle.

Verdict: worth it, small and gold. Skip anything with a hook a scarf can find until March.

6. Pearls, on wool

Pearls belong on knitwear more than on silk, a position I will hold against anyone in a blouse. A princess-length strand disappears against a crew neck, so go to at least 20 inches; over a turtleneck, go to 22 inches or beyond. How to Wear Pearls in 2026: The New Rules has the styling advice.

Coleman Douglas Pearls is a London pearl specialist founded by Chrissie Douglas, with a workshop attached to its showroom and an appointment-led service. Mini freshwater drop earrings in silver were £175 when I looked, and strands climb into the thousands, so decide your budget before the appointment.

Verdict: worth it, and the easiest piece here to wear the day it arrives.

Buying it, and the case for repair

Gold traded at $4,383.45 an ounce on 18 September 2026, about 19% above a year earlier, and its record of about $5,600 was set in late January this year. Gold jewellery is priced against that number, which is the strongest argument I know for the Bayswater principle: fixing what you own costs bench time, and replacing it costs gold.

Ask three questions of any seller, whether on Portobello Road on a Saturday or across a counter: show me the back, show me all three marks, and tell me what has been repaired or replaced. A good seller enjoys these questions. A bad one tells you where you are.

Worth it?

Buy the brooch. Put it on the coat before the clocks go back on 25 October, and the dark at 4.50pm becomes an audience instead of an opponent. Everything else here can wait for a birthday, a better month, or an overdraft that has stopped making eye contact.

FAQ

What jewellery should I wear in autumn?

Wear pieces that work with layers: an antique brooch on the coat, a signet ring, a matinee-length chain that sits on knitwear, small earrings that clear a scarf, and pearls. Structure matters more than sparkle once the clocks go back, because most evenings are lit by lamps.

What are the birthstones for September, October and November?

On the modern list, September is sapphire, October is opal and tourmaline, and November is topaz and citrine, per Brilliant Earth. Opal is soft enough (5.5–6.5 on the Mohs scale) that earrings and pendants suit it better than rings.

What necklace length works over a jumper?

A matinee length of 20–24 inches or an opera length of 28–36 inches sits on top of knitwear. A princess length of 17–19 inches sits just below the collarbone and gets hidden by knitwear: a crew neck needs at least 20 inches and a turtleneck 22 or more, per AJLuxe.

Will a claw-set ring catch on knitwear?

It can. Bezel settings have a smooth surface that catches less, and claws with sharp or unfinished tips are the usual cause of snagging, according to Alan Bick and Lily Dia Jewellery. A jeweller can re-finish or re-tip the claws, and re-tipping is typically needed every 5–10 years anyway.

Where can I buy antique jewellery in London?

Portobello Road Market has its antiques arcades open on Saturdays, Grays on Davies Street is listed by Visit London as open Monday to Friday, and The Antique Jewellery Company sells online and from a Mayfair townhouse by appointment. Ask to see the back of any piece, all three hallmark symbols on gold, and what has been repaired or replaced.

How do I check a UK gold hallmark?

Look for three compulsory symbols: a sponsor's mark, a fineness mark such as 375 (9ct) or 750 (18ct), and an Assay Office mark, per the government's hallmarking guidance. A fineness number on its own is a manufacturer's stamp and not a hallmark, per Assay Assured. Gold over 1 gram must carry the full mark to be sold as gold, subject to the exemptions in the Act.
