If you’re exploring new materials for your designs, gold-filled jewellery is a fantastic choice. Whether you’re new to it or unsure how it compares to solid gold or gold plated options, you’re not alone—many jewellery makers find the term “gold filled” unfamiliar or even intimidating at first. That’s exactly why we’ve created this guide: to demystify gold-filled jewellery, highlight its benefits, and show you how to work with it confidently and creatively.
What is Gold-Filled Jewellery?
Gold-filled jewellery, sometimes known as “rolled gold” or “gold bonded,” is made by mechanically bonding a thick layer of gold to a base metal, usually brass, using heat and pressure. This process creates a permanent bond between the two metals, preventing the gold from peeling, flaking, or wearing off easily.
To legally qualify as “gold filled,” the gold content must be at least 5% of the item’s total weight. In contrast, gold plated items typically contain less than 0.05% gold—a much thinner and more fragile layer.
Types of Gold-Filled Material:
-
Single clad: 5% gold layer on one side of the brass core.
-
Double clad: Gold split evenly (2.5%) on both sides of the core.
-
Wire clad: Gold evenly layered around the full circumference of wire.
Gold-Filled vs. Gold-Plated vs. Solid Gold
| Feature | Gold-Filled | Gold-Plated | Solid Gold |
|---|---|---|---|
| Gold Content | 5% by weight | <0.05% | 100% |
| Durability | High | Low | Very High |
| Tarnish Resistance | Strong | Weak | Strong |
| Solderability | Good with care | Poor | Excellent |
| Price | Affordable | Very Affordable | Expensive |
| Lifespan | 10–30 years | 6–12 months | Lifetime |
Gold-filled jewellery offers a modern, cost-effective alternative to solid gold. It’s far more durable and valuable than gold-plated jewellery—making it ideal for pieces that need to last and shine for years to come.
How to Work with Gold-Filled Jewellery
Soldering Tips
There is no such thing as “gold-filled solder,” so a colour match is key. Use:
-
9ct or 14ct yellow gold easy solder for best visual compatibility.
Avoid overheating, as this can cause:
-
Restain: A type of sub-layer oxidation that ruins the finish.
-
Alloying: The gold layer may mix with the brass core, leaving unsightly dark joints.
Ideal soldering temperatures:
-
Between 690°C and 788°C (just enough to flow the solder).
-
Avoid exceeding 843°C (14ct gold melting point) or 900°C (brass core melting point).
If any brass becomes exposed, gold plating can restore uniformity and prevent tarnish.
Cutting and Filing
Avoid aggressive cutting or filing, which can expose the brass and reduce the legal gold weight. If cutting is necessary:
-
Plate exposed areas afterward.
-
Maintain at least 5% gold weight post-modification to preserve the gold-filled classification.
How to Care for Gold-Filled Jewellery
Cleaning Methods
Gold-filled jewellery is easy to care for with the right tools:
-
Mild soapy water with a soft toothbrush to remove residue.
-
Soft cotton cloth (or jewellery cloth without harsh chemicals).
-
Ultrasonic cleaning: Use a safe solution, checking items every 2–3 minutes.
-
Tumble polishing: Stainless steel shot only—non-abrasive and preserves the gold layer.
Storage Tips
-
Store in a dry, clean environment.
-
Place tissue paper between pieces to avoid scratches.
-
Protect from abrasive surfaces and tools during handling.
Design and Usage Tips
Do:
-
Use easy gold solder.
-
Polish gently with soft cloths.
-
Combine with softer metals (e.g., silver) to minimize wear.
-
Offer as a premium yet affordable option to customers.
-
Educate customers about the gold content and value.
Don’t:
-
File or cut aggressively.
-
Over-polish—this reduces the gold layer thickness.
-
Wear alongside harder metals like steel.
-
Spray with perfume or hairspray.
-
Cast with gold-filled metal (it’s not designed for casting).
