1. Understanding Gold-Filled vs. Gold-Plated vs. Rumělka

Funkce Plněné zlatem Zlaté Rumělka
Gold Layer Thickness 5% of total weight (2.5-5µm) 0.5-2.5µm 2.5-5µm (on sterling silver)
Základní kov Mosaz, měď, or S925 silver Jakýkoli kov Only S925 silver
Trvanlivost 10-30 roky (with care) 6 months-3 years 2-5 roky
Cena $$$ $ $$

Why Gold-Filled?
✔ More durable than plating
✔ Legally requires 5% gold content (US FTC standard)
✔ Does not flake or wear off easily


2. Selecting Premium Brass Alloy for Base Metal

Best Brass Alloys for Gold-Filled Earrings

  1. C260 (Cartridge Brass – 70% Cu, 30% Zn)

    • Excellent malleability

    • High corrosion resistance

  2. C220 (Commercial Bronze – 90% Cu, 10% Zn)

    • Warmer gold-like hue

    • Better for intricate designs

Why Not Pure Copper?

  • Too soft for long-term wear

  • Prone to oxidation


3. The Role of S925 Silver in Gold-Filled Jewelry

When to Use S925 Silver as a Base

  • For hypoallergenic earrings (Nickel-sensitive customers)

  • Higher-end collections (Sterling silver adds value)

How Brass & S925 Silver Work Together

  1. Brass Core (Provides structure & dostupnost)

  2. S925 Silver Overlay (Ensures skin safety)

  3. Gold-Filled Layer (Adds luxury finish)


4. Gold Bath Electroplating Process (Krok za krokem)

Krok 1: Preparing the Brass/S925 Base

  • Ultrazvukové čištění (Removes oils & debris)

  • Acid Pickling (Removes oxidation)

Krok 2: Electroplating Bath Setup

  • Gold Solution: 14K-18K gold cyanide bath

  • Proudová hustota: 0.5-1 A/dm² (Controls plating thickness)

  • Temperature: 120-140°F (50-60° C.)

Krok 3: Plating the Earrings

  1. Initial Strike Layer (Thin gold adhesion layer)

  2. Main Plating (2.5-5µm tloušťka)

  3. Post-Plating Rinse (Removes excess chemicals)

Krok 4: Post-Processing

  • Annealing (Heat treatment for durability)

  • Leštění (Mirror or matte finish)


5. Kontrola kvality & Testování trvanlivosti

A. Testování tloušťky (XRF Analyzer)

  • Minimum 2.5µm gold layer (FTC compliance)

B. Testování adheze (Tape Peel Test)

  • Gold layer should not flake off

C. Pokazatel odporu (Test v solném spreji)

  • 24-hour exposure to check corrosion resistance


6. Design Considerations for Gold-Filled Earrings

Popular Styles

  • Hoop Earrings (Klasický, high demand)

  • Studové náušnice (Minimalista, lehký)

  • Dangle Earrings (Luxury appeal)

Možnosti přizpůsobení

  • Rytina (Laser or hand-engraved details)

  • Gemstone akcenty (Diamanty, Cz, narození kamenů)


7. Udržitelné & Etická výroba

Recycled Brass & Zlato
Non-Cyanide Plating Alternatives
Fair-Trade Gold Sourcing


8. Společné výzvy & Řešení

Issue Řešení
Uneven Plating Adjust current density
Gold Wear Over Time Use thicker plating (5µm+)
Allergic Reactions Ensure nickel-free brass

9. Market Trends in Gold-Filled Jewelry

  • Rising Demand for Affordable Luxury

  • Přizpůsobitelné & Personalizované vzory

  • Eco-Conscious Jewelry Buyers


Závěr

By combining premium brass alloys with advanced gold bath plating, you can produce high-quality S925 silver earrings that rival solid gold at a fraction of the cost.
