High Networth

When Pandora announced its shift away from sterling silver towards platinum-plated collections, the story made retail headlines. For high-net-worth individuals, the more pressing question is what that signals about the insurance value of what’s already in your jewellery box.

As materials change, prices shift and collections evolve, insurance arrangements that once provided adequate cover can quietly fall short, often without the policyholder realising it.

Replacement Value – Not Sentiment or Resale

For many clients, jewellery carries both financial and sentimental value. From an insurance perspective, however, the focus is on the cost of replacing an item like-for-like at today’s market rates.

The distinction between market value and replacement value is widely misunderstood.

Secondary market or auction values rarely align with current retail pricing. A piece that may have modest resale value can carry a significantly higher replacement cost – particularly when brand, craftsmanship or material changes are factored in.

Where manufacturers alter materials, as we are now seeing, the position becomes more nuanced. A piece originally specified in sterling silver may no longer exist in that form. Its modern equivalent, may be platinum-plated and may differ in both cost and availability. If schedules are not updated accordingly, this can create challenges at the point of claim.

Market Volatility and Its Impact on Jewellery Valuations

Precious metal markets have seen sustained volatility in recent years. Silver has been particularly affected, but movements in gold, platinum and palladium have also materially influenced jewellery valuations and replacement costs.

Valuations carried out even two or three years ago may materially understate current replacement costs. The conventional guidance of reviewing every three to five years remains a useful benchmark, but in periods of significant market movement – such as the gold and silver price surges of recent years – earlier reassessment is warranted and often on annually.

Accumulation Risk Within Jewellery Collections

One of the more understated risks we encounter is the gradual accumulation of jewellery. Individually, pieces may appear modest in value, however collectively they can represent a significant exposure.

Standard household policies typically impose low single article limits, requiring individual items above a certain value, for example £2,500, to be separately specified. Equally important, and often overlooked, is the overall position: the total value of a collection can quietly exceed policy assumptions without ever being formally declared.

For high-net-worth clients, specialist policies typically provide broader cover and greater flexibility. However, even within these arrangements, accurate overall valuations remain essential to ensure the integrity of cover.

Branded Jewellery and the Importance of Currency

Established brands such as Tiffany & Co., Cartier or Georg Jensen offer a clearer framework for valuation and replacement. Their documented designs and pricing structures provide insurers with a reliable reference point but this consistency can also create a false sense of security.

Collections evolve, pieces are discontinued, and pricing adjusts, often significantly over relatively short periods. A valuation that was entirely appropriate several years ago may now understate the true replacement cost. For bespoke items, the position is more complex still, particularly where gemstones or unique design elements are involved. In these cases, specialist valuation is critical.

When to Revisit Jewellery Valuations

No single trigger should prompt a valuation review but several circumstances make it particularly timely.

This is particularly relevant where:

• Items have been acquired or gifted in recent years
• Existing valuations are more than a few years old
• Collections have grown gradually over time
• Or where pieces are materially influenced by precious metal or gemstone pricing

Where any of these apply, the gap between recorded and actual replacement value is likely to be widest. Speaking to your adviser about commissioning an up-to-date valuation is a straightforward step that can prevent significant complications at the point of claim.

The Role of Specialist Valuation

Accurate jewellery insurance relies on more than a broad estimate of worth.

Professional valuations provide a detailed assessment of materials, craftsmanship, provenance and current market conditions. This is particularly important for:

• High-value individual pieces
• Branded collections subject to price changes or discontinuation
• Bespoke or unique items
• Jewellery incorporating coloured gemstones, where pricing can be especially variable

Without this level of detail, establishing an appropriate replacement value can be challenging — particularly at the point of claim.

Understanding Jewellery as a Dynamic Asset

Jewellery is often viewed primarily through a personal or sentimental lens. From a risk perspective, however, it is better understood as a dynamic asset class.

Values are influenced not only by ownership and acquisition, but by:

• Commodity price movements
• Brand positioning and retail strategy
• Design changes and product availability
• Broader market demand

Each of these factors can move independently, and their combined effect on replacement cost is not always immediately visible.

Final Thought

The changes underway in the jewellery market – shifting materials, evolving brand strategies and volatile precious metal prices – are a useful prompt to revisit cover, but they are not the whole story. Even without dramatic market events, well-documented collections gradually diverge from their recorded figures.

Maintaining accurate cover is less about reacting to headlines and more about recognising that jewellery, like any high-value asset, is a dynamic holding that requires the same periodic attention you would give to any other significant part of your financial affairs.

Escape of water – leaks from internal plumbing, fittings, or heating systems – is the most common cause of insurance claims in the high‑net‑worth (HNW) property market. UK insurers pay out around £1.8 million every day for water damage, yet it remains one of the least appreciated risks.

This guide explains why high‑value homes face a heightened exposure to water damage and highlights the vulnerabilities that matter most, from underfloor heating and basements to swimming pools and smart home systems. It also outlines practical steps owners can take to reduce the likelihood and impact of a claim.

Why High-Value Homes Face a Greater Escape of Water Risk

A standard home with simple plumbing presents a contained risk. Large country houses, London townhouses with basements, and properties with pools or integrated technology have far more complex systems and far more potential failure points.

Multiple bathrooms, hydronic underfloor heating, leisure spaces, and sophisticated building management systems all increase the chance of a leak. In HNW homes, the cost of reinstatement is also higher due to specialist materials, bespoke finishes, and valuable contents.

Escape of water accounts for roughly 30% of UK home insurance claim costs. While the average claim is £5,000–£10,000, losses in high‑value homes can be significantly greater.

Key Vulnerabilities in High-Value Properties

Multiple Bathrooms, En Suites, and Wet Rooms

More bathrooms mean more pipework, seals, and joints. Silicone seals deteriorate over time, often unnoticed, and slow leaks behind tiles or beneath wet room floors can cause major structural damage. Locating leaks behind bespoke finishes can be complex, making comprehensive trace and access cover essential.

Underfloor Heating Systems

Hydronic underfloor heating uses extensive pipe networks hidden beneath flooring. A pinhole leak can spread widely before detection, and finding the source often requires lifting high‑value finishes such as stone or hardwood. Specialist trace and access cover is particularly important.

Basements and Lower Ground Floors

Basements used as kitchens, cinemas, gyms, or plant rooms are especially vulnerable. Water reaching a basement can render a property uninhabitable, with alternative accommodation and specialist reinstatement costs often exceeding the physical damage.

Swimming Pools, Hot Tubs, and Leisure Facilities

Pool plant rooms combine large volumes of water with pumps, heating systems, and chemical dosing equipment. Failures can release significant water into the building. Outdoor pools also face winter risks from frozen pipework.

Smart Home and Building Management Systems

Integrated systems controlling heating, lighting, and security can amplify the impact of a leak. Water affecting a central controller can disrupt multiple systems, requiring specialist contractors and extending repair times.

Second Homes and Holiday Properties

Unoccupied properties are at particular risk. A slow leak can go undetected for weeks, causing extensive damage to structure, finishes, and contents.

Reducing Escape of Water Risk: A Practical Checklist

• Ensure everyone knows where the stopcock is and that it operates freely.
• Have pipework inspected annually by an accredited plumber.
• Lag exposed pipework in unheated areas.
• Maintain minimum heating in unoccupied properties during cold weather.
• Install smart leak detection systems for early alerts. Including automatic water shut off valves to prevent any further water from escaping the pipes and apparatus.
• Inspect and replace silicone seals annually.
• Prepare pools and spas properly for winter, draining exposed pipework.
• Have underfloor heating systems checked annually for pressure drops or joint issues.

Taking proactive steps to understand and manage escape of water risk helps protect both the fabric of a home and the peace of mind of those who live in it.

Paul Brayne – Senior Client Adviser

Owning or occupying an apartment comes with a range of insurance considerations that are often misunderstood or overlooked. While the building itself is typically insured under a block policy arranged by the managing agent, this cover rarely extends to everything inside the apartment or to the occupier’s legal responsibilities. From contents, valuables and tenants’ improvements to personal liability and legal expenses, understanding what insurance cover is required is essential to ensure you are fully protected – whether you are an owner-occupier, tenant or landlord.

• • General Contents, Art & Antiques and Jewellery & Watches belonging to the occupier. Cover for all such items is provided for loss or damage often on a worldwide basis usually from the following causes; Fire, Explosion, Smoke, Lightning, Earthquake, Storm or Flood, Theft or Attempted Theft, Malicious Damage, Escape of Water from any fixed water installation, draining or heating installation, Accidental Damage & Accidental Loss.

• • Tenants Improvements (Fixtures & Fittings) including Bathrooms, Kitchens, Fitted Cupboards, Fitted Flooring excluding Carpets which should be included within General Contents.

Please note the overarching insurance policy for the Building, which is normally arranged via the managing agent, may include this cover automatically, but any improvements made by the leaseholder or sometimes the tenant would need to be notified to the managing agent to ensure sufficient cover is in place. Some Buildings insurance policies purely cover the fabric of the property and do not cover any improvements made by the occupier/owner. In any event, cover can be included within a Contents insurance policy arranged by the owner/occupier. 

Reference should also be made to the terms of the lease agreement which may override any covers in place on the overarching Buildings Insurance policy.

• • Contents policies automatically provide cover for Personal Liability and Employers Liability in respect of Domestic Employees. This cover is usually a minimum of £5,000,000 in respect of Personal Liability and £10,000,000 for Employers. Policies provide protection against legal expenses and damages if the policyholder or family members residing at the home are held liable for third-party bodily injury or property damage. It covers worldwide incidents, employer liability for domestic staff, and specialised areas like libel, slander, or public access to property.

Key components of personal liability cover in a Household policy typically include:

Worldwide Personal Liability: Protects against claims for accidents occurring anywhere in the world, not just at home.
Property Owner’s Liability: Covers incidents involving the home(s), including land, gardens, and, in some cases, holiday or second homes.
Domestic Staff Employer’s Liability: Protects against claims from household employees (e.g., housekeepers, gardeners) for injuries sustained while working.
Legal Expenses/Defence Costs: Covers legal fees for defending claims, as well as potential compensation payments for injuries, property damage, or wrongful eviction.
Public/Visitor Liability: Covers claims if a visitor is injured on the property.

• • Contents policies usually extend to cover Legal Expenses for employment disputes, contract disputes, bodily injury, clinical negligence, property protection, tax protection, legal defence, jury service and court attendance, education admissions appeals and planning application refusal and appeals.

• • Cover is often included for Home Emergencies for example: Plumbing and drainage, heating failure, power supply failure, toilet units, home security, lost or stolen keys and vermin infestation.

• • If the occupier is a tenant and is renting the apartment on a short-term tenancy agreement, all of the above covers except Fixtures and Fittings belonging to the landlord are still relevant and a Household Contents policy should still be taken out. In addition, many policies also extend to include Tenants Liability where the occupier becomes legally liable for damage caused to the Building and Landlords Contents.

• • If the owner is not the occupier and is a landlord renting out their apartment, a Landlords Policy should be taken out to cover Landlords Fixtures and Fittings (if not covered by the block policy), and Landlords Contents. A Landlords policy will provide cover for the events listed above and can often be extended to include Accidental Damage & Theft by the Tenant and sometimes even Rent Guarantee. Landlords Legal Expenses would be specific to a property rental and would extend to cover disputes with tenants. These policies would also include Property Owners Liability. 

Artificial intelligence is finding its way into almost every corner of our lives and the world of valuations is no exception. For collectors of fine art, rare jewellery, luxury watches and unique antiques, you may wonder if AI can replace traditional in-person valuations.

The short answer is: AI can help, but it cannot replace expert human valuers, especially when your collection includes rare or high-value pieces.

Below is our collector-friendly look at why.

Why AI Seems Appealing

There is no doubt that AI has made impressive strides. With the ability to scan large databases and recognise patterns instantly, it can:

• Give quick, directional estimates for mass-produced items
• Compare common designs or widely traded brands
• Help organise or catalogue large collections

For standard items with lots of historical sale data, AI can be incredibly efficient. But this is also where its usefulness tends to end.

Where AI Falls Short for High-Value or Unique Items

1. Rare items simply don’t have enough data

AI needs thousands of comparable sales to make accurate predictions. For one-off pieces, private sales, or items with specialist markets, those datasets don’t exist and AI has no reliable foundation to work from.

2. It can’t judge the subtleties that experts see

The value of a painting, watch or piece of jewellery isn’t just about what it is – it’s also about the:

• Condition
• Craftsmanship
• Restoration history
• Authenticity
• Provenance
• Patina, wear and overall ‘story’

These nuances can dramatically influence a valuation, yet AI cannot meaningfully assess them through photographs alone.

3. Algorithms can be biased or opaque

AI often favours what it recognises, e.g., artists who frequently appear at auction, popular design periods, or particular styles. Rare or unusual works may be undervalued simply because they fall outside the algorithm’s comfort zone.

4. AI valuations are rarely acceptable for insurance

For insurance purposes, valuations must be:

• Defensible
• Documented
• Recognised by insurers
• Completed by a qualified professional

AI-generated figures lack accountability and can leave clients underinsured in the event of a loss.

Why Expert Valuers Remain Indispensable

A professional valuation offers far more than a number on a page. It provides:

• A trained eye – Valuers can assess condition, craftsmanship, and authenticity in ways technology cannot replicate.
• Access to private markets – Many sales of high-end art, jewellery or antiques never appear online. Experts have the relationships and insight to understand true market value.
• Provenance verification – Human expertise is essential for reviewing certificates, exhibition history, and ownership lineage – all vital for insurance and resale.
• Insurance-ready documentation – For high-value collections, insurers expect robust professional valuations. They rely on these reports to tailor cover and ensure you’re properly protected.

What This Means for Collectors and High-Value Insurance

If you own rare, unique or high-value pieces:

• Don’t rely on AI-only valuations – They are unlikely to satisfy insurers or fully reflect your item’s worth.
• Invest in professional valuations – This helps ensure accurate cover, avoids underinsurance, and provides peace of mind.
• Use AI as a convenient first step, not the final word – It can speed up organisation and research but cannot confirm true value.

A proper valuation is about understanding an item’s story, significance and condition which is far more than what an algorithm can glean from image recognition. AI has its place and its role will no doubt continue to grow but for serious collectors – especially those insuring valuable, sentimental or unique pieces – in our opinion nothing replaces the depth, judgement and accountability of an experienced valuer.

Fine jewellery is more than an accessory. It is a long-term investment, a personal statement, and often a piece of family heritage. For high-net-worth (HNW) individuals in the UK, jewellery collections can include rare diamonds, signed designer pieces, antique gemstones and one-of-a-kind creations whose value increases over time.

As demand rises, so does risk. The counterfeit jewellery market has expanded rapidly, with sophisticated replicas and forged documentation being sold online to unsuspecting buyers. These imitations can deceive even experienced collectors and the financial impact can be significant.

This guide explores why counterfeit jewellery is now a major concern in the UK, what to watch out for when purchasing online, and how to safeguard your collection with effective due diligence and specialist insurance.

The UK’s Expanding Counterfeit Jewellery Market

The global counterfeit luxury market is worth billions, and jewellery is one of its fastest-growing sectors. The UK, with its strong market for luxury brands and pre-owned jewellery, has become a key target.

Today’s counterfeiters are equipped with:

• High-quality synthetic stones
• Advanced metal plating that mimics precious metals
• Replica serial numbers and hallmarks
• Forged branded boxes, certificates, and receipts
• Professional-looking photography for online listings

To the untrained eye, and even to some experienced collectors, these replicas appear entirely genuine.

Online Marketplaces: The Largest Source of Fake Jewellery

UK consumers increasingly buy luxury goods online, but open marketplaces remain high-risk environments. Unlike established jewellers or auction houses, many online platforms do not verify sellers or authenticate items.

Common red flags on online marketplaces include:

1. Untraceable or anonymous sellers – Many profiles have limited sale history or unverifiable details.
2. Prices that seem too good to be true – Significantly discounted luxury pieces are often counterfeit.
3. Lack of clear provenance – Reputable sellers can explain an item’s history; fraudulent sellers cannot.
4. High-pressure ‘limited offer’ tactics – Counterfeiters often use urgency to discourage detailed scrutiny.

For HNW buyers, the risk goes beyond the initial purchase. Buying a counterfeit item can create insurance complications.

The Hidden Threat: Fake Receipts, Boxes, and Certificates

A growing issue in the UK luxury market is the sale of legitimate-looking branded receipts and documents online.

Fraudsters can now source:

• Genuine store receipts
• Luxury brand packaging
• Replacement certificates
• Warranty cards

These allow counterfeiters to pass off fake jewellery as authentic, including matching paperwork to multiple counterfeit items. This makes independent verification essential.

Insurance Implications: Why Counterfeits Leave You Unprotected

Most high-value jewellery insurance requires:

• Genuine receipts
• Accurate valuations
• Professional authentication
• Verified ownership history

If a piece later turns out to be counterfeit, cover is typically invalid, meaning a loss, theft, or damage claim may be declined. Counterfeit items can also distort the total value of your jewellery schedule, creating wider issues in the event of a claim.

How UK Jewellery Collectors Can Protect Themselves

• Buy from reputable, verified sources only – Choose UK-based jewellers, accredited auction houses, or recognised luxury retailers.
• Request independent authentication – A certified gemmologist or specialist jeweller can confirm a piece’s legitimacy before purchase.
• Maintain detailed documentation – Secure digital and physical copies of all receipts, certificates, and valuations.
• Schedule regular valuations – Ensure your insurance reflects the true market value of your jewellery.
• Consult your broker before major purchases – They can verify what documentation they require.

Why Specialist Jewellery Insurance Is Essential

Specialist high-net-worth jewellery insurance typically provides:

• Worldwide all-risks cover
• Agreed-value settlements
• Lower excesses
• Cover for pairs and sets
• Access to specialist valuers and experts

The right broker helps ensure only authenticated, properly valued pieces are insured, reducing risk and protecting your investment.
