Are you wondering what 18-karat gold filled means? Well, let's start with the basics. Karat is a unit of measurement for purity in gold. The "karat" (abbreviated as "kt" or "k") of an item tells you how many parts out of 24 are pure gold. So, 18 karat gold means that 18 out of 24 parts are pure gold. So, 18-karat means it is 75% gold.

Now that we know what karats are let's talk about gold-filled jewelry. Gold-filled simply means that a jewelry piece consists of a solid layer of gold bonded to another metal through intense heat & pressure. The layer of pure gold must be at least 1/20th the weight of the entire piece in order for it to be considered "filled." That being said, 18-karat gold-filled jewelry means that the piece consists of a layer of 18-karat gold bonded to another metal.



The process of creating rolled gold begins with a solid sheet of 18-karat gold. The manufacturer places this layer over a base metal sheet (usually made of brass). The manufacturer feeds the two metal sheets through a rolling mill, which uses high heat and pressure to weld the metals together.

The finished sheet of bonded metal is then molded and cut to create the desired piece of jewelry. The final step is to give the jewelry a high polish, resulting in a beautiful and long-lasting piece of 18k gold-filled jewelry.


18-karat gold-filled jewelry is an excellent alternative to solid gold jewelry because it has all the same beauty and luster as solid gold but is much more affordable. Plus, it's more durable than solid gold because it doesn't scratch or dent easily. So, if you're looking for beautiful jewelry that won't break the bank, 18-karat gold filled is a great option!
