Every piece of second-hand jewellery carries a story, but at 365 Carat, we make sure it also carries the assurance of authenticity and quality. Whether it’s a delicate Victorian brooch, a bold mid-century bracelet, or an elegant Art Deco ring, each item undergoes a thorough process before it earns a place in our curated collection.
Restoring and authenticating vintage jewellery isn’t about making it look brand new—it’s about preserving its character while ensuring it’s safe, wearable, and true to its origin. Here’s how we do it.
Step One: Expert Authentication
Authentication begins the moment a piece enters our hands. We assess everything from its materials to its markings, asking critical questions about its age, origin, and construction.
What We Examine:
- Metal content: Using acid tests, electronic testers, and visual inspection, we confirm the purity of metals such as gold (e.g., 9ct, 14ct, 18ct), silver, and platinum.
- Hallmarks and maker’s marks: We identify and date the piece using national hallmarking systems (e.g., the UK’s Assay Office symbols) and any maker signatures, which often indicate brand and provenance.
- Gemstone verification: Diamonds and coloured stones are inspected for authenticity, treatment, and quality. If needed, we consult certified gemologists to confirm details such as natural vs. synthetic stones and the presence of enhancements.
- Era and style: We evaluate design elements, settings, and craftsmanship techniques to situate the piece within a particular historical context—whether Georgian, Edwardian, Art Deco, or beyond.
Every assessment is recorded, and we document each item’s defining characteristics to ensure transparent representation in our listings.
Step Two: Gentle Restoration
Once authenticity is established, we consider whether restoration is needed. The goal is not to erase time, but to respect it—allowing the jewellery’s age and charm to shine through, while restoring its strength, wearability, and visual appeal.
Common Restoration Techniques Include:
- Stone tightening and resetting: Ensuring gemstones are secure, particularly in older settings where prongs may have worn down.
- Cleaning and polishing: Using non-invasive, professional-grade methods to remove grime and surface dullness while preserving patina.
- Rebuilding worn elements: When necessary, parts such as ring shanks, earring backs, or clasps are rebuilt using matching materials to maintain integrity.
- Re-tipping prongs: Strengthening the metal that holds gemstones in place without altering the original setting.
- Chain and clasp repair: Strengthening or replacing fragile links and closures to ensure durability and usability.
We avoid over-polishing or replacing components that contribute to the item’s age-specific character. In many cases, the evidence of gentle wear only enhances a piece’s charm.
When We Leave It Untouched
Not every piece needs restoration. Some are in excellent condition when sourced, while others may carry marks or slight imperfections that form part of their history. In these cases, we may leave the item untouched, clearly noting any signs of age so you know exactly what you’re purchasing. This approach is part of our commitment to honesty and respect for vintage integrity.
