If you’ve ever shopped for jewelry and come across the term “gold filled,” you might’ve asked yourself, “Wait… is this real gold filled or what?” You’re not alone. A lot of people confuse gold filled with gold plated or even solid gold. The truth? Gold filled jewelry is a unique material that offers a sweet spot between quality and price, and it’s especially popular in the world of permanent jewelry.
In this article, we’ll break down what gold filled really means, how it’s made, why it’s different from gold plating, and how to take care of it so it lasts for years. We’ll also explain how it fits into the world of permanent jewelry and what markings to look for if you’re trying to spot the real deal.
What Does Gold Filled Mean?
Gold filled jewelry is made using a mechanical bonding process where a thick layer of real gold is pressure-bonded to a base metal. Unlike gold plating, which is just a thin coating of gold electroplated onto metal, gold filled material has a much thicker layer of gold.
In fact, to legally be called gold filled in the U.S., the gold must make up at least 5% of the item's total weight. That might not sound like much, but it's actually 100x thicker than gold plating in most cases.
So basically:
Gold filled = thick, durable layer of real gold fused onto brass.
Gold plated = thin, often short-lived coating of gold.
Is Gold Filled Real Gold?
Sort of. The outer layer that touches your skin is real gold, usually 14k or sometimes 12k. The difference is in how far that gold goes. With solid gold, it’s gold all the way through. With gold filled, it’s a thick shell of real gold around a base.
The best part? Most people can't tell the difference just by looking at it. Gold filled jewelry has the same warm glow, rich tone, and quality look that you’d expect from high-end gold pieces, but without the massive price tag.
Why Gold Filled is Perfect for Permanent Jewelry
Permanent jewelry is all about longevity. Since you’re literally welding a chain onto someone’s wrist or ankle (no clasps, no taking it off), you need material that can stand the test of time. That’s where gold filled shines.
-
Durability: It won’t flake off like gold plated jewelry. You can wear it in the shower, while swimming, or even at the gym.
-
Skin: Because the surface is real gold, it’s safe for most people with sensitive skin.
-
Cost effective: It gives you the luxury look of solid gold without the shocking price.
That’s why so many permanent jewelry artists, including those who shop at Stella Rose Jewelry Supply, rely on gold filled chains for their services.
How Gold Filled Jewelry Is Made
The process behind gold filled jewelry is part of what makes it so special. Here's how it typically works:
-
Gold alloy (usually 14k) is layered over a brass core.
-
The metals are bonded together using heat and pressure, creating a permanent bond.
-
The resulting material is then rolled into sheets or wires, which are used to make chains, jump rings, and other jewelry components.
This is a mechanical process, not chemical, which means the gold doesn’t just sit on the surface. It’s part of the piece, which is why it won’t wear away easily like electroplated gold might.
Common Identifying Marks on Gold Filled Jewelry
If you’re trying to tell whether something is really gold filled, the markings can help. Here are some of the most common ones:
-
“1/20 14K GF” – This means that 1/20th (or 5%) of the item’s total weight is 14 karat gold.
-
“14/20 GF” – Same as above but just written differently.
-
“GF” – A general abbreviation for gold filled.
Unlike solid gold, gold filled jewelry may not always be stamped, especially if it’s a small or handmade piece. When in doubt, buy from trusted suppliers (like us!) who clearly label their materials.
If a charm or chain looks like it was melted and poured into a mold, it cannot be gold filled. That’s because gold filled material isn’t cast it’s made from solid sheets, wire or tubes of gold bonded over a base metal, then cut, stamped, or formed into shape.
Unfortunately, there are some dishonest shops out there. Something important to keep in mind, when you find something that is labeled as gold filled, if the price seems too good to be true, it probably is!
How to Take Care of Gold Filled Jewelry
While gold filled is durable, it's still a precious metal and deserves a little love. Here’s how to keep it shining:
-
Avoid harsh chemicals – Chlorine, bleach, and cleaning agents can dull the finish.
-
Wipe it down regularly – Use a soft cloth to remove oils and sweat after wearing.
-
Use mild soap and water – If it needs a deeper clean, a quick soak in warm, soapy water followed by a rinse will do the trick.
-
Store it seperately(If it is not permanent) – Keep it in a soft pouch or a dry place so it doesn't rub against other jewelry.
If you're in the permanent jewelry business, we recommend bundling your services with a small care kit, customers appreciate the extra effort, and it helps preserve the jewelry long term.
Here's a litte tip: Stella Rose Jewelry Supply offers professional jewelry cleaners and brushes great for gold filled maintenance.
How to Spot Quality Gold Filled Chains
Not all gold filled jewelry is created equal. Look for:
-
Consistent color and shine – The chain should look smooth, not patchy or dull.
-
Reliable suppliers – Make sure you're buying from a supplier who meets FTC standards for gold filled materials.
-
Strong links – Especially important for permanent jewelry.
