Gold Filled Structure
Gold filled jewelry consists of a thick layer of gold mechanically bonded to a base metal (such as brass, silver, or stainless steel). The gold layer must constitute at least 5% of the total weight, providing excellent durability and color retention.

Solid Gold Structure
Solid gold jewelry is made entirely of gold, with no base metal core. It comes in different karat values: 24K (pure gold), 18K (75% gold), 14K (58.5% gold), etc. Solid gold offers high value, excellent malleability, and superior resistance to tarnish.

Custom Gold-filled Jewelry on Different Base Metal

Copper

For heavy jewelry, copper is often used as the base material. It’s a key component in brass and bronze alloys and features a unique color and smooth surface that facilitates bonding with gold. Gold-filled jewelry with a copper base is highly durable and hypoallergenic, making it suitable for individuals with metal allergies.

Brass

Brass is another metal that blends well with gold. Its natural yellowish, warm color is similar to gold, so only a thin layer of gold is needed to achieve a perfect match. Brass is an alloy made of copper and zinc. While it can be somewhat malleable, gold-filled brass becomes suitable for creating a variety of jewelry pieces.

Sterling Silver

Sterling silver is also highly versatile. It can be combined with copper sheets to create stunning patterns through a technique called Mokume Gane. To achieve optimal results, at least 25 alternating layers of sterling silver and copper should be used. The final product boasts highly visible and luxurious patterns.

Definition

Gold purity simply refers to its karats (k). 24k is pure gold in its raw state therefore, it needs to be broken down to create gold-filled jewelry. In most cases, gold-filled jewelries contain 14k gold and 18k.

 

Gold-to-Metal Ratio

When an accessory is said to contain 14k gold, it contains 58.3% gold and 41.3% metal. The lower the karats the higher the base metal content. Some others also make use of 12k which is approximately 50% gold and 50% metal.

 

Rarely Used Purity

Although, some producers go as low as using 8k which is approximately 33.3% gold and 66.7% metal. This sort of gold-filled jewelry is below par, and might not perform to expectations.

PURE GOLD: Used Rarely in jewelry
24 K
75% GOLD: Excellent Balance Between Purity &Strength
