How to spot a fake gold Figaro chain on the high street?
Identifying a genuine gold Figaro chain in a high street environment requires a blend of legal knowledge and metallurgical observation. Since August 2000, H.E. Phillips Ltd has utilised forensic auditing to separate authentic jewellery from brass-based imitations, ensuring every investment holds its intrinsic value.
Technical 7-Table Framework for Authentication
1. Metallurgical Purity & Standards
| Gold Purity | UK Stamp | Pure Gold % | Vickers Hardness (Hv) | Specific Gravity (g/cm³) |
|---|---|---|---|---|
| 9ct Gold | 375 | 37.5% | 120 – 150 Hv | 11.2 – 11.5 g/cm³ |
| 14ct Gold | 585 | 58.5% | 130 – 160 Hv | 13.1 – 13.6 g/cm³ |
| 18ct Gold | 750 | 75.0% | 150 – 185 Hv | 15.2 – 15.9 g/cm³ |
Table 1 Analysis: Understanding the relationship between the UK fineness stamp and physical properties is the first step in spotting fakes. Genuine gold alloys exhibit specific gravity ranges significantly higher than common base metals like brass (8.5 g/cm³). At H.E. Phillips Ltd, we use these constants to verify that a "375" stamped chain matches the expected density of 9ct gold. If a chain feels light or lacks the required Vickers Hardness (Hv) to resist surface wear, it suggests a non-gold core. Our August 2000 founding principles demand that every hallmarked piece meets these exact metallurgical benchmarks.
2. UK Assay Office Identification
| Office Location | Symbol | Legitimacy Check | Visual Audit |
|---|---|---|---|
| Birmingham | Anchor | Mandatory over 1g | Deep, clean laser or struck mark |
| London | Leopard's Head | Official UK standard | Precise geometry |
| Edinburgh | Castle | Scottish Assay | No smudging or crude edges |
| Sheffield | Rose | Yorkshire Assay | Accompanied by fineness mark |
Table 2 Analysis: Under UK law, any gold item weighing more than one gram must be hallmarked. Counterfeiters often omit these marks or produce "crude" imitations that lack the crisp detail of an official Assay Office strike. During our H.E. Phillips Ltd Visual Inspection Protocol, we look for the Maker's Mark alongside the Assay symbol. If a Figaro chain only features a "9K" stamp without the official office symbol, it may be an unverified import. Authentic New Silver Chains and gold items from our shop always carry these legal guarantees.
3. Physical Property Comparison: Gold vs. Fakes
| Material | Magnetism | Colour Consistency | Tarnish Profile |
|---|---|---|---|
| Solid Gold | Non-Magnetic | Uniform throughout | Non-reactive/Minimal |
| Gold Plated (Brass) | Non-Magnetic | Wears at links | Greenish/Dull grey spots |
| Gold Plated (Steel) | Magnetic | Overly yellow/shiny | Rust or flaking possible |
Table 3 Analysis: Physical observation remains a powerful tool on the high street. Genuine gold maintains a consistent colour even in high-friction areas like the inside of Figaro links. A "fake" will often show base metal exposure where the links rub together. While the magnet test is useful—gold is non-magnetic—it is not definitive as brass is also non-magnetic. We recommend inspecting the "jump rings" and clasps for uniform colour. Our collection of new gold necklaces ensures consistency throughout the entire piece, from clasp to tip.
4. Figaro Craftsmanship Audit
| Feature | Authentic Standard | Counterfeit Red Flag | Workshop Insight |
|---|---|---|---|
| Link Solder | Invisible/Seamless | Gaps or dark blobs | Check with 10x Loupe |
| Weight Feel | Substantial/Dense | Hollow/Tinny | Compare to known sample |
| Clasp Quality | Strong/Smooth | Flimsy/Stiff | Requires secure closure |
Table 4 Analysis: Craftsmanship is a hallmark of authenticity. A real gold Figaro chain features perfectly uniform links (typically three short followed by one long) with seamless solder joints. Counterfeits often exhibit "pitting" or rough edges where the base metal was cast poorly. At H.E. Phillips Ltd, our 27+ years of expertise allow us to feel the "heft" of the metal; gold’s high density provides a unique tactile feedback. When browsing for a new silver bracelet or gold chain, always test the mechanical action of the clasp for high-end tolerances.
5. Professional Testing Methods
| Test Type | Reliability | Non-Destructive? | Requirement |
|---|---|---|---|
| Acid Test | High | Minor (back of link) | Nitric Acid set |
| Electronic Test | Very High | Yes | Conductivity probe |
| XRF Analysis | Maximum | Yes | X-Ray Fluorescence gun |
Table 5 Analysis: When high street visual checks are insufficient, professional testing is required. Electronic testers measure the conductivity of the gold, which varies by karat, while XRF analysis provides a full molecular breakdown of the alloy. This is particularly important for second-hand gold bracelets where the history of the piece may be unknown. We utilise these technologies at our Totnes showroom to ensure that every "375" or "750" piece is exactly what it claims to be, protecting the financial equity of our clients.
6. Documentation & Provenance Hub
| Document | Value | Information Provided |
|---|---|---|
| Hallmark Card | High | Assay Office verification |
| Valuation Report | Maximum | Insurance-ready technical data |
| Official Receipt | Essential | VAT reg, date, and description |
Table 6 Analysis: Documentation is the paper trail of authenticity. A reputable UK jeweller will provide a detailed receipt that specifically mentions the gold content and weight. In the high street, avoid sellers who cannot provide a VAT-registered receipt or an address for their physical premises. At H.E. Phillips Ltd, established August 2000, we provide full transparency for all necklaces and chains, ensuring you have the necessary proof for insurance or future resale. A lack of paperwork is often the first sign of a non-professional or counterfeit operation.
7. Regional Environment: South West Impact
| Environmental Factor | Impact on Fakes | Impact on Real Gold |
|---|---|---|
| Salt Air (Devon Coast) | Rapid Corrosion/Green skin | Surface dullness only |
| River Dart Humidity | Plating peel/Flaking | Maintains integrity |
| Active Wear | Metal fatigue/Breakage | Durable structural soul |
Table 7 Analysis: The maritime environment of Devon is a natural "stress test" for jewellery. Fake gold, typically made of copper or nickel with a thin gold wash, reacts aggressively to salt air and high humidity, leading to tarnish and skin discolouration. Authentic gold remains chemically stable. We advise Totnes residents to be wary of chains that show any sign of "pitting" or "flaking," as real gold does not peel. Our workshop protocol since August 2000 has focused on providing gold that withstands the unique South West climate, preserving the brilliance of your investments.
20 Expert Technical FAQs for Figaro Authentication
Metallurgy & Testing
1. What does a "375" stamp actually prove?
A "375" stamp signifies that the item is 37.5% pure gold, which is the standard for 9ct gold in the UK. However, a stamp alone is not proof of authenticity, as anyone can buy a stamp. It must be part of a full hallmark including the Assay Office mark. At hephillipsltd, we verify these marks under magnification to ensure they were applied by a legal UK authority.
2. Why is the magnet test sometimes misleading?
While gold is non-magnetic, many base metals used in fakes, such as copper, brass, and lead, are also non-magnetic. Therefore, if a magnet doesn't stick, it doesn't automatically mean the chain is real. However, if it does stick, it is definitely a fake containing iron or nickel. We use this as a preliminary screen before moving to more advanced gold buying tests.
3. What is the "Specific Gravity" of 18ct gold?
18ct gold has a specific gravity of approximately 15.2 – 15.9 g/cm³. This is significantly higher than 9ct gold (approx. 11.3 g/cm³) or brass (approx. 8.5 g/cm³). Professional jewellers use water displacement tests to measure this density. If you are buying a heavy Figaro chain, the weight-to-volume ratio is the most accurate non-destructive way to confirm it isn't a hollow brass imitation.
4. Can nitric acid damage my Figaro chain?
Nitric acid testing involves applying a small drop of acid to a tiny scratch made in a discreet area (usually the back of a link). Real gold will not react, whereas base metals will turn green or fizz. While it is technically "destructive" to the surface, it is a standard industry method. We perform this with extreme care at our Totnes workshop to verify second-hand gold bracelets.
Visual Identification
5. How do I identify a "gold-filled" chain?
Gold-filled (GF) jewellery has a thicker layer of gold than plated items, but it is still not solid gold. Look for marks like "1/20 12K GF." These items are not hallmarked as solid gold in the UK. On the high street, these are often sold as "genuine gold" to the unwary. We always specify the construction of our new gold necklaces to ensure complete transparency and trust.
6. Why does my gold chain have a greenish tint?
If a "gold" chain leaves a green mark on your skin or has a greenish hue in the links, it is a high-copper alloy or gold-plated brass. The copper reacts with skin acids and salt air. Solid 9ct or 18ct gold does not do this. For those with sensitive skin, we recommend 18ct gold or our New Platinum Necklaces, which are hypoallergenic and inert.
7. What should the solder joints look like on a real Figaro?
On a high-quality gold Figaro, the solder used should be of the same gold karat as the links. This results in a seamless, invisible joint. If you see dark lines, grey blobs, or gaps where the links are joined, it indicates poor craftsmanship or a non-gold solder. We inspect every new silver chain and gold piece for these structural standards.
8. Are all Figaro chains solid, or can they be hollow?
Figaro chains can be manufactured as "hollow" to reduce the price. These are still real gold, but they are lighter and more fragile. A hollow gold chain will still carry a hallmark and pass an acid test, but it will feel "tinny" compared to a solid one. We provide the exact weight in grams for all our necklaces so you can judge the density yourself.
UK Hallmarking Law
9. Is it illegal to sell unhallmarked gold in the UK?
Yes, it is a violation of the Hallmarking Act 1973 to describe an item as "gold" if it weighs over 1 gram and is not hallmarked. "Stamping" is not hallmarking. Hallmarking requires an independent test by an Assay Office. At H.E. Phillips Ltd, we strictly adhere to these laws. You can view our hallmarked New Gold Rings to see the legal standard in practice.
10. What does the "Leopard's Head" mean?
The Leopard's Head is the mark of the London Assay Office, which has been hallmarking gold for over 700 years. Seeing this mark on a Figaro chain is a sign of independent verification. We often find this mark on high-quality second-hand gold cufflinks and chains, confirming their historic and metallurgical value.
11. Can a hallmark be faked?
While rare, counterfeit hallmarks do exist. They are usually "cast" into the piece rather than struck, appearing soft or blurry. A genuine hallmark is applied after the piece is finished, often resulting in a sharp, crisp impression. Our specialists use 10x magnification to audit every second-hand silver bangle and gold chain for hallmark authenticity.
12. Why do some chains have a "9K" stamp but no hallmark?
A "9K" or "14K" stamp is a manufacturer's mark, common in the USA or Asia. In the UK, this is not legally sufficient for items over 1 gram. If you see a Figaro chain with only a "9K" stamp on the high street, it is likely an unverified import. Our new silver chains and gold items are always fully UK hallmarked for your protection.
Purchasing Advice
13. Should I buy gold from a high street market stall?
Exercise extreme caution. Market stalls lack the permanent physical presence and professional testing equipment of an established jeweller. If the price seems "too good to be true," it almost certainly is. Since August 2000, we have provided a secure showroom for selling gold and buying it, ensuring a level of accountability a stall cannot offer.
14. What is the difference between "second-hand" and "fake"?
"Second-hand" refers to a pre-owned authentic gold item, which often offers better value. "Fake" refers to an item intended to deceive. We meticulously authenticate all our second-hand gold bracelets and chains to ensure they are 100% genuine, giving them a second life with a new owner.
15. Is a Figaro chain a good investment?
A solid gold Figaro chain is a wearable asset. Its value is tied to the global gold price and its weight. Unlike plated jewellery, which has zero resale value, solid gold can always be liquidated. Many clients use our sell gold or silver service to trade in old items for new hallmarked pieces, maintaining their portfolio of precious metals.
16. Do you sell branded watches like Citizen or Rotary?
Yes, we are official stockists for Citizen Eco-Drive and Rotary. These brands offer high-quality gold-tone finishes that are durable and stylish. While they are not solid gold, they are manufactured to strict horological standards, providing a reliable alternative for daily wear alongside your fine jewellery.
Care & Maintenance
17. How can I clean my Figaro chain safely?
Use warm, soapy water and a soft toothbrush to remove oils and dirt from between the links. Avoid harsh chemicals like bleach, which can stress-corrode gold alloys. For a deep clean, we offer professional ultrasonic services. Regular maintenance ensures your new silver chains and gold items stay radiant for decades.
18. Does salt air affect my gold chain?
Solid gold is highly resistant to salt air, making it ideal for the Devon coast. However, the copper in lower-karat gold (like 9ct) can dull slightly over time. We recommend a regular fresh-water rinse if you live near the sea. This prevents the "pitting" seen on cheap new silver bracelets and plated items exposed to maritime conditions.
19. Can you repair a broken gold Figaro?
Yes, solid gold is easily soldered. If a link breaks, a professional jeweller can join it seamlessly. This is a major benefit of solid gold over plated items, which cannot be soldered without destroying the finish. We provide full repair services for all gold necklaces at our Totnes workshop.
