Introduction
A jewellery workshop holds more value per square foot than almost any other craft premises, and a good deal of that value is not the maker's own property. Customers' inherited gold, loose stones, work at the setter and finished commissions awaiting hallmarking all sit in different places at different times.
This guide covers the hallmarking duty and where its exemption genuinely ends, the transit exposure hallmarking creates, remodelling a customer's own materials, how insurers categorise stock, bench hazards from torches to polishing motors, skin reaction claims, and selling at fairs, online and through galleries.
Key Takeaways
- Above the exemption weights, selling an unhallmarked article described as precious metal is an offence under the Hallmarking Act 1973.
- The exemption is from physical hallmarking only — other parts of the Act still apply to lighter items.
- Work in transit to the assay office, a setter or a plater is frequently outside premises-based stock cover.
- Customers' materials held for remodelling are not your stock and are often separately limited or excluded.
- Stock security conditions — safe rating, overnight storage, alarm — are judged against what was actually in place at the time of a theft.
The Hallmarking Duty and the Exemption Weights
Hallmarking is the one genuine legal obligation that shapes a UK jewellery business, and it is not optional above certain weights.
Under the Hallmarking Act 1973, an article described in the course of trade as gold, silver, platinum or palladium must carry a UK-recognised hallmark unless it falls below an exemption weight. Those weights are gold under 1 gram, silver under 7.78 grams, platinum under 0.5 gram and palladium under 1 gram. Above them, selling an unhallmarked article described as precious metal is an offence.
The Exemption Is Narrower Than Makers Assume
Official guidance makes a point worth repeating: the exemption is an exemption from physical hallmarking, not from the rest of the Act. Restrictions on how an article may be described continue to apply below the exemption weight. A maker who believes small items sit entirely outside the legislation has misread it.
Items in Transit to and from the Assay Office
Hallmarking creates a logistical exposure that few other crafts have: finished, high-value work must leave your premises, travel to an assay office, and come back.
During that journey the pieces are typically at their most valuable — fully made, finished and often already sold or commissioned — and they are outside your workshop, outside your control and frequently outside the terms of a contents policy that covers stock at the premises.
The same gap applies to every other outward movement: stones sent to a setter, work sent to a plater or engraver, pieces going to a photographer, and finished items posted to customers. Each leg is a separate question about whether cover follows the goods.
Working With a Customer's Own Gold and Stones
Remodelling is a large part of many jewellery businesses, and it brings into the workshop material that cannot be replaced at any price.
A customer arrives with a grandmother's ring to be remade, a parent's wedding band to be melted into something new, or inherited stones to be reset. The metal has a scrap value that is easy to calculate. The item's actual value to the customer is sentimental, and that is the value they will have in mind if something goes wrong.
Where the Risk Concentrates
Melting down is irreversible. Stones can chip during unsetting, and emeralds and opals are considerably more fragile than diamonds. Old settings fail unpredictably once heat or pressure is applied. And with several customers' materials in a small workshop at once, there is a straightforward identification risk.
It is also worth being plain in writing about the risks of unsetting older stones before work begins rather than after a stone has chipped.
Stock: Metal, Stones and Finished Work
A jewellery workshop holds unusually high value in an unusually small volume, which makes it a deliberate target rather than an incidental one.
Insurers typically separate categories a maker may think of as one thing: raw metal and casting grain; loose stones; work in progress at the bench; finished stock awaiting sale; and customers' property held for repair or remodelling. That last category is not your stock at all, and is frequently subject to a separate limit or excluded from ordinary stock cover.
Security Conditions Are Conditions
Policies covering precious metal and stones commonly attach requirements: a specified safe rating, stock locked away overnight, a particular alarm specification, limits on how much may be left out. These are not recommendations, and a theft claim will be assessed against what was actually in place on the night.
Exhibitions and Off-Site Display
Stock taken to a fair, a gallery, a trunk show or a customer's home for viewing has left the premises, and the cover position changes with it.
Bench Hazards: Torches, Pickle and Polishing Motors
A jewellery bench is a small workshop containing open flame, acid and fast-rotating machinery, usually in a room never designed as an industrial space.
Torches and Fire
Soldering means a live flame near a wooden bench, cloth and paper. Where the workshop is in a home, a garden building or a shared studio, a fire does not stay confined to the business — it becomes a buildings claim, and potentially one involving neighbouring units.
Pickle and Chemicals
Pickling solutions, oxidising agents and plating chemicals are corrosive and produce fumes. Ventilation, storage and disposal all matter, and a spill in a shared building affects more than your own bench.
Polishing Motors
The polishing motor is the most consistently underestimated hazard in the trade. A mop turning at speed will snatch a chain, a ring or a finger, and injuries are typically to the hand. Where anyone else uses that machine — an employee, an apprentice, a student on a workshop course — both the employer duty and the injury exposure apply.
Metal Sensitivity and Skin Reactions
Jewellery is worn against skin continuously, which makes reaction claims a real category here rather than a theoretical one.
Nickel is the best-known sensitiser and is subject to restrictions on the rate at which it may be released from items in prolonged contact with skin. Because alloys, solders and plating can each introduce nickel, a maker who has not asked their supplier about composition may not know what is in the finished piece.
Other reactions arise from plating wearing through to a base metal, from residues of polishing compound or pickle left on a finished item, and occasionally from adhesives used in setting. Jewellery sold for initial or healing piercings carries a materially higher risk than an ordinary ring or pendant and is worth declaring separately.
Allegations of this kind concern the product rather than the service, which is a different category of cover from injury caused on your premises.
Selling at Fairs, Online and Through Galleries
How a maker sells changes the exposure as much as what they make.
Craft Fairs and Markets
At a fair you are trading in a public space with high-value portable stock, a temporary display and members of the public within arm's reach. The risks are theft and distraction theft, a display unit or lighting causing injury, and damage to the venue. Most organisers require evidence of public liability cover and many specify a minimum limit as a condition of booking a stand.
Online and Distance Selling
Selling online brings consumer cancellation rights and the question of who bears the risk of loss in transit to the customer. Bespoke and personalised items are treated differently from stock items under consumer law, which is worth understanding before a dispute rather than during one.
Galleries and Sale or Return
Stock placed with a gallery on sale or return is your property sitting on someone else's premises. Whose insurance responds if that gallery is burgled is a question worth settling in writing at the outset, not after the event.
Resizing and Repairing Customer Pieces
Repair work is steady income and carries a risk profile distinct from making new pieces.
Applying heat to an unfamiliar item produces unwelcome surprises: unseen previous repairs failing, solder running, stones damaged by heat, and pearls or opals reacting badly to processes diamonds tolerate without complaint. Antique and vintage pieces are simultaneously the most delicate and the most valued.
A resize that goes wrong on a customer's own wedding ring is a small job carrying disproportionate emotional weight. As with remodelling, the practical protection is a written intake record and a frank conversation about risk on anything old, thin or unusually set.
What Jewellery Cover Will Not Do
The limits worth knowing before they are tested.
Hallmarking and Trading Standards Penalties
Fines for describing or selling unhallmarked precious metal are regulatory penalties and are generally not insurable.
Unexplained Disappearance
Many policies distinguish theft with evidence of forced entry from stock that is simply missing. Small, high-value items and loose stones are exactly where that distinction bites.
Security Conditions Not Met
Stock left out overnight where the policy required it safed, or an alarm not set, is the most common reason a jewellery theft claim is reduced or declined.
Remaking at Your Own Cost
Redoing a commission the customer is unhappy with, or refunding it, is a trading cost rather than an insured loss.
Known Circumstances and Deliberate Acts
If a customer is already unhappy about a commission or a repair when you arrange cover, that needs declaring rather than carrying quietly into a new policy. Deliberate substitution of metal or stones is fraud, not an insured loss.
Frequently Asked Questions About Jewellery Maker Insurance
Do I legally have to hallmark the jewellery I make?
Under the Hallmarking Act 1973, an article described in the course of trade as gold, silver, platinum or palladium must carry a UK-recognised hallmark unless it falls below an exemption weight. Those weights are gold under 1 gram, silver under 7.78 grams, platinum under 0.5 gram and palladium under 1 gram.
Does the exemption weight mean small items are outside the law entirely?
No, and official guidance makes this point specifically. The exemption is an exemption from physical hallmarking, not from the rest of the Hallmarking Act. Restrictions on how an article may be described still apply to items below the exemption weight.
Is my work covered while it is at the assay office or in the post?
Not automatically. Stock cover frequently means stock at your premises, so pieces in transit to and from an assay office, at a setter or plater, or posted to a customer may need transit cover and cover for property at another trader's premises. A parcel lost between you and the assay office is a classic uninsured loss in this trade.
What happens if I damage a customer's inherited stone while remodelling?
This is a genuinely difficult exposure, because the metal has a scrap value but the item's value to the customer is sentimental. Unsetting can chip stones, particularly emeralds and opals, and melting down is irreversible. Photographing and weighing everything on intake, recording stone counts and existing damage, and explaining the risks in writing beforehand are the practical protections.
Are customers' items held for repair covered by my stock insurance?
Usually not in the same way. Customers' property held for repair or remodelling is not your stock, and is frequently subject to a separate limit or excluded from ordinary stock cover. It is worth checking specifically rather than assuming your stock figure covers it.
What if a customer has a skin reaction to a piece I made?
That is a products-type allegation rather than a service one. Nickel is the best-known sensitiser and is subject to restrictions on release from items in prolonged skin contact, and because alloys, solders and plating can each introduce it, composition is worth confirming with your suppliers. Jewellery sold for initial or healing piercings carries a higher risk and is worth declaring separately.
Do I need insurance to sell at craft fairs?
Most organisers require evidence of public liability cover as a condition of booking a stand, and many specify a minimum limit. Separately, stock taken to a fair has left your premises, so whether it remains covered away from the workshop is a distinct question from the liability the organiser is asking about.
Do I need to tell my insurer if I run jewellery-making workshops?
Yes. Members of the public operating a polishing motor or a soldering torch under your supervision is materially different from you working alone at your own bench. The polishing motor is the most consistently underestimated hazard in the trade, and hand injuries from it are common.
Conclusion
Two things do most of the protective work in this trade: an intake record for every customer item — photographed, weighed, stones counted, existing damage noted — and a clear understanding of exactly where your cover stops being premises cover.
If you post finished work to an assay office, check that first. It is where makers most often discover they were carrying the risk themselves.
