Expert Advice on Preserving the Value of Your Silver Figaro Chain
The silver Figaro chain remains a cornerstone of horological and jewellery collections due to its distinctive 3:1 link ratio. Preserving its monetary and aesthetic value requires a forensic understanding of sterling silver metallurgy and environmental chemistry, particularly within the maritime context of Totnes and the South West.
Technical 7-Table Framework for Silver Preservation
1. Metallurgical Composition & Physical Properties
| Metal Grade | Silver Purity % | Vickers Hardness (Hv) | Specific Gravity (g/cm³) | Primary Alloy |
|---|---|---|---|---|
| Fine Silver (999) | 99.9% | 25 – 35 Hv | 10.49 g/cm³ | None |
| Sterling Silver (925) | 92.5% | 75 – 100 Hv | 10.36 g/cm³ | Copper (7.5%) |
| Argentium Silver | 93.5% | 100 – 120 Hv | 10.30 g/cm³ | Germanium |
Table 1 Analysis: Understanding the Vickers Hardness (Hv) is critical for Figaro chains. While pure silver is too malleable for structural jewellery, the 925 Sterling Silver standard utilised at H.E. Phillips Ltd increases the hardness to roughly 75-100 Hv. This is achieved by alloying silver with copper, which provides the necessary tensile strength for the elongated Figaro links. However, this copper content is the primary catalyst for tarnish. By identifying the specific gravity and hardness, our workshop can determine the appropriate polishing pressure required to restore lustre without removing excess metal, thereby preserving the chain's gram weight and financial value.
2. Tarnish Kinetics & Chemical Reactions
| Reactant | Chemical Product | Visual Indicator | Severity |
|---|---|---|---|
| Hydrogen Sulphide (H₂S) | Silver Sulphide (Ag₂S) | Brown/Black Film | High (Progressive) |
| Sodium Chloride (Salt) | Silver Chloride (AgCl) | Dull Grey Patina | Moderate (Abrasive) |
| Chlorine | Surface Pitting | White/Brittle Spots | Critical (Structural) |
Table 2 Analysis: Silver does not "rust" via oxidation; it tarnishes via sulphidation. The formation of Silver Sulphide (Ag₂S) is a surface reaction triggered by atmospheric sulphur. Left untreated, this layer can lead to microscopic pitting, which permanently alters the surface topography of the Figaro links. At H.E. Phillips Ltd, we use this chemical profile to recommend specific cleaning agents that reverse the sulphidation process without the use of abrasives. Maintaining the molecular integrity of the link surfaces is the only way to ensure the chain retains its high-specular reflectivity over decades of use.
3. South West Regional Environmental Audit
| Environmental Variable | Local Impact (Devon) | Technical Consequence |
|---|---|---|
| Maritime Salt Air | High (South Coast) | Accelerated Chlorination |
| River Dart Humidity | Consistent (Totnes) | Moisture-led Sulphidation |
| Agricultural Ammonia | Regional (Rural Devon) | Stress Corrosion Cracking |
Table 3 Analysis: The South West maritime climate presents unique challenges for silver jewellery. High humidity levels along the River Dart facilitate the transport of sulphur compounds to the metal surface. Furthermore, the salt-rich air of coastal Devon introduces chlorides that can cause "stress corrosion" at the solder points of Figaro links. Our regional care protocol advises Totnes residents to perform weekly fresh-water rinses to remove salt deposits. This prevents the abrasive "grinding" effect that salt crystals can have within the moving parts of the Figaro pattern, effectively extending the mechanical lifespan of the chain.
4. Mechanical Wear & Link Integrity
| Link Component | Wear Pattern | Failure Risk | Maintenance Action |
|---|---|---|---|
| Elongated Figaro Link | Internal Rubbing | Thinning/Elongation | Lubricated Polish |
| Solder Joints | Stress Fractures | Chain Separation | 10x Loupe Audit |
| Lobster/Bolt Clasp | Spring Fatigue | Loss of Asset | Annual Tension Test |
Table 4 Analysis: The Figaro's alternating link pattern creates specific friction points where the smaller links interface with the larger ones. Over years of wear, this "metal-on-metal" contact leads to thinning. Our workshop protocol involves a forensic measurement of these contact zones to ensure they have not reached a critical failure point. We also audit the clasp spring—a common point of mechanical failure. By identifying wear early, H.E. Phillips Ltd can perform preventative soldering, maintaining the structural soul of the piece and preventing the total loss of the jewellery asset.
5. Cleaning Methodology Effectiveness
| Method | Abrasiveness | Effectiveness | Expert Recommendation |
|---|---|---|---|
| Microfibre Polishing Cloth | Ultra-Low | Surface Lustre | Daily Maintenance |
| Ultrasonic Cleaning | Zero (Mechanical) | Intricate Crevices | Bi-Annual Professional |
| Silver Dip (Chemical) | Low-Moderate | Rapid Desulphidation | Emergency Only |
Table 5 Analysis: Not all cleaning methods are equal. Home-remedies like toothpaste are strictly avoided at H.E. Phillips Ltd because their abrasive particles (Mohs hardness ~3-4) can scratch the softer silver surface (Mohs hardness ~2.5). This creates a "matte" finish that attracts tarnish faster. Our professional ultrasonic tanks use high-frequency sound waves to create cavitation bubbles that dislodge grime from the intricate Figaro link junctions without any physical abrasion. This preserves the original "factory polish" of the metal, which is essential for maintaining the chain's resale and heirloom value.
6. Storage Protocol Comparison
| Storage Type | Air Exposure | Tarnish Protection | Scratch Risk |
|---|---|---|---|
| Open Jewellery Tray | Maximum | None | High |
| Velvet Lined Box | Moderate | Low | Minimal |
| Airtight Poly-Bag + Strip | Minimal | Maximum | Zero |
Table 6 Analysis: Proper storage is the most cost-effective preservation tool. Silver should never be stored in direct contact with chemically treated wood or high-acid papers, as these release gases that accelerate tarnishing. We recommend the use of anti-tarnish strips containing activated carbon or silver-reactive polymers. By creating a micro-environment free of Hydrogen Sulphide, the rate of sulphidation is reduced by over 90%. In the humid Devon climate, an airtight seal is mandatory to prevent the moisture-catalysed reactions discussed in Table 3.
7. Authority Comparison: Specialist vs Generalist
| Service Metric | H.E. Phillips Ltd (Specialist) | High-Street Generalist |
|---|---|---|
| Establishment History | Founded August 2000 | Variable |
| Metallurgical Knowledge | Forensic/Technical | Retail-Only |
| On-site Repair Hub | Yes (Totnes Workshop) | Off-site/Outsourced |
Table 7 Analysis: Technical accountability is the hallmark of a specialist. At H.E.

Unlike generalist retailers who may lack a deep understanding of silver’s chemical properties, we provide a holistic care service that includes mechanical audits and regional environmental advice. This level of expertise ensures that your silver Figaro chain is treated as a metallurgical asset rather than a disposable accessory, securing its value for future generations.
20 Expert Technical FAQs for Silver Figaro Preservation
Metallurgy & Chemistry
1. Why does my silver Figaro chain turn black?
This is a chemical reaction between the silver (specifically the copper alloy) and sulphur in the air. This forms silver sulphide, a dark layer. It is a surface reaction, not permanent damage, but it requires removal to prevent pitting. For those looking to replace a damaged piece, our new silver chains offer the highest grade sterling silver to ensure consistent metallurgical performance.
2. Is "925" silver the same as Sterling Silver?
Yes. The "925" hallmark indicates that 92.5% of the metal is pure silver, while the remaining 7.5% is typically copper. This ratio is the international standard for durability and lustre. In the UK, this is a legal requirement for items over 7.78g. We verify all new silver chains to ensure they meet these strict Assay Office standards.
3. What is Vickers Hardness in relation to Figaro chains?
Vickers Hardness (Hv) measures a metal's resistance to indentation. Sterling silver sits at ~75-100 Hv. This is important because the Figaro's link-on-link action causes wear. A chain with lower hardness would stretch or deform faster. At H.E. Phillips Ltd, we assess hardness to ensure the mechanical integrity of every piece we service or sell.
4. Can perfumes affect my silver chain's value?
Yes, cosmetics and perfumes contain chemicals that react with silver alloys, accelerating tarnish and causing a dull film. We recommend the "last on, first off" rule. If your chain has become severely dulled, you may consider a sell gold or sell silver consultation to trade in for a fresh, high-lustre replacement.
Cleaning & Maintenance
5. How often should I clean my Figaro chain?
For daily wear, a quick buff with a soft cloth once a week is ideal. However, a professional deep clean is recommended annually. This removes oils and salt from the link junctions. If you find your current chain is too difficult to maintain, browse our new silver bracelets for easier-to-clean alternative styles with similar aesthetic appeal.
6. Is ultrasonic cleaning safe for silver?
Yes, ultrasonic cleaning is highly effective for silver Figaro chains as it reaches inside the link junctions. However, it should only be performed by professionals like H.E. Phillips Ltd to ensure the vibration doesn't loosen the clasp or any stones. For those with vintage pieces, our second-hand silver chain collection is meticulously ultrasonically cleaned before sale.
7. Can I use toothpaste to clean my chain?
No. Toothpaste is too abrasive for the soft surface of silver (Mohs 2.5). It creates micro-scratches that actually catch more tarnish over time. Use a dedicated silver cloth instead. If your chain is beyond home repair, you can visit us in Totnes to sell gold or sell silver and upgrade to a new, pristine piece.
8. What should I do if a link is thinning?
Thinning links are a sign of mechanical wear. Stop wearing the chain and bring it to our Totnes workshop. We can solder the link to reinforce it. This is a common maintenance task for second-hand silver chain assets to ensure they remain secure and valuable for another generation of wearers.
Regional Care (Devon/South West)
9. Does the River Dart air affect my silver?
Yes, the humidity near the River Dart in Totnes increases the rate of sulphidation. Moisture acts as a catalyst for the chemical reaction between silver and sulphur. We advise local residents to store their jewellery in airtight containers. For a lower-maintenance alternative in humid climates, explore our new gold necklaces, which are more resistant to atmospheric tarnish.
10. Is salt air in Devon harmful to my chain?
Salt air contains chlorides that can cause corrosion, especially at the solder points of a Figaro chain. If you live near the coast, rinse your jewellery in fresh water daily. If your silver has become pitted by salt, it may be time to browse our new silver chains for a fresh, structurally sound replacement.
11. Should I wear my silver chain in the sea?
No. Saltwater and sand are highly abrasive. Additionally, the cold water can shrink your fingers/neck, increasing the risk of losing the item. If you have lost a piece to the sea, we can help you find a replacement in our second-hand silver bracelets or chain sections at our Fore Street shop.
12. Can hard water in Totnes affect silver?
Hard water can leave mineral deposits (limescale) on your jewellery, making it look dull. Always dry your chain thoroughly with a soft cloth after it gets wet. For those who want a worry-free metal for water exposure, consider our new platinum necklaces, which are inert and do not react to water or minerals.
Storage & Security
13. How should I store my Figaro chain to prevent tangling?
Always fasten the clasp before storing. Lay the chain flat or hang it vertically. Tangling can cause "kinking," which weakens the links. If you prefer a sturdier, less tangle-prone option, our second-hand silver bangles offer a rigid alternative that maintains its value exceptionally well without the risk of knots.
14. What are anti-tarnish strips?
These are small papers treated with materials that absorb atmospheric sulphur. Placing one in your jewellery box creates a protective environment for your silver. This is essential for protecting a second-hand silver pendant charm or chain from dulling while not in use. We use these protocols in our own showroom to ensure maximum brilliance.
15. Is it safe to store silver in a velvet box?
Only if the velvet is high-quality and acid-free. Some cheap velvets are treated with chemicals that actually accelerate tarnishing. We recommend silk or microfibre pouches. If you need a more durable storage-friendly asset, consider our new gold ring collections, which are far more resistant to storage-related chemical reactions.
16. How can I tell if my clasp is failing?
Test the tension. If the lever doesn't snap back instantly, the internal spring is fatigued. This is the most common cause of jewellery loss. We can replace clasps on all new silver chains and vintage pieces in our on-site Totnes workshop to ensure your investment stays around your neck.

17. Does H.E. Phillips Ltd sell watches to match silver chains?
Yes. We stock several brands that complement silver jewellery perfectly. For a modern technical look, our Casio range is ideal. For a more classic feel, we are official stockists for Rotary and Timex, offering stainless steel models that mimic the cool tones of silver.
18. Can I add charms to a Figaro chain?
While possible, we recommend ensuring the charms aren't too heavy, as this can cause the links to elongate. For a dedicated charm piece, browse our second-hand gold charms and bracelets, which are designed to handle the specific mechanical stresses of multiple attachments.
19. Do you buy old silver Figaro chains?
Yes, we offer competitive rates through our sell gold or sell silver service. We evaluate the gram weight and purity on-site in Totnes. This is an excellent way to recycle a broken or unwanted chain into credit toward a new gold earrings purchase or a fresh chain.
