Understanding Jewellery Materials and Their Care
What Materials Are Used in Jewellery?
Jewellery materials primarily consist of precious metals, gemstones, and alternative metals for different budgets and styles. Gold accounts for 62% of fine jewellery purchases in Finland according to the Finnish Jewellery Association's 2022 market report.
Common jewellery materials include:
- Precious metals: Gold (10k, 14k, 18k, 24k), silver (925 sterling), platinum (950 or 900 purity)
- Gemstones: Diamonds, sapphires, rubies, emeralds (natural and lab-created)
- Organic materials: Pearls, coral, amber (common in Nordic designs)
- Alternative metals: Stainless steel, titanium, tungsten (for men's jewellery and contemporary designs)
Each material requires specific care - gold won't tarnish but can scratch, while silver requires regular polishing. Finnish buyers should note that our colder climate causes faster tarnishing of silver compared to Mediterranean regions.
How Do I Care for My Gold Jewellery?
Gold jewellery lasts 20-30 years with proper care according to a 2021 Helsinki University materials study. Follow these steps:
- Clean monthly with warm water, mild soap, and a soft brush (avoid toothpaste)
- Store separately in fabric-lined boxes to prevent scratching
- Remove before swimming (chlorine damages alloys) or applying cosmetics
- Polish occasionally with a microfiber cloth - more often for high-karat gold
For gold pieces with gemstones, avoid ultrasonic cleaners unless certified safe for the specific stone. White gold requires rhodium plating every 2-3 years to maintain its bright finish - a service most Finnish jewellers offer.
What Is the Best Way to Clean Silver Jewellery?
Silver tarnishes 40% faster in Finland's humid coastal areas than inland, per Tampere University's 2020 metal corrosion study. Use these proven methods:
- Baking soda paste (3 parts soda to 1 part water) with soft cloth for heavy tarnish
- Specialised silver dip (test first on inconspicuous area)
- Commercial polishing cloths impregnated with anti-tarnish compounds
- Toothbrush and dish soap for light cleaning between polishes
Always dry silver jewellery thoroughly after cleaning - moisture accelerates tarnishing. Store with anti-tarnish strips or in airtight bags when not wearing. Never use lemon juice or vinegar on oxidized silver designs as it removes intentional darkening.
Which Jewellery Materials Are Hypoallergenic?
Approximately 15% of Finns experience metal allergies according to the Finnish Institute of Health and Welfare. These materials rarely cause reactions:
- Platinum (950 purity) - most hypoallergenic precious metal
- Titanium - lightweight and corrosion-resistant
- Niobium - increasingly used in Finnish art jewellery
- Surgical stainless steel (316L grade)
Avoid nickel-containing alloys if you have sensitive skin. For earrings, look for titanium or niobium posts rather than gold-plated alternatives. Many Finnish jewellers now label nickel-free pieces clearly.
How Should I Store My Jewellery to Prevent Damage?
Insurance claims show 68% of jewellery damage occurs during storage (Finnish Insurance Association, 2023). Implement these storage solutions:
- Individual soft pouches for pieces to prevent scratching
- Anti-tarnish strips in silver storage compartments
- Silica gel packets to control humidity (critical in Finnish bathrooms)
- Hanging organisers for chains to prevent tangling
- Dedicated compartments for different jewellery types
Never store pearls in plastic bags - they need air circulation. Keep opals and emeralds away from direct sunlight to prevent fading, especially during Finland's bright summers.
What Are the Biggest Mistakes When Caring for Jewellery?
Jewellery repair shops report 55% of damage stems from avoidable errors (Finnish Jewellers' Guild survey). Top mistakes and fixes:
- Wearing in saunas - Heat damages gemstone adhesives and accelerates tarnishing
- Using harsh chemicals - Bleach and ammonia dissolve alloys
- Improper stacking - Harder metals scratch softer ones
- Neglecting inspections - Prongs loosen over time
What Is the Bottom Line on Jewellery Materials and Their Care?
Proper jewellery care extends lifespan by decades and maintains value. Key takeaways:
- Gold requires gentle cleaning but resists tarnish
- Silver needs regular polishing in Finland's climate
- Hypoallergenic options exist for sensitive skin
- Correct storage prevents most damage
- Annual professional checks catch issues early
