Gold Purity

There are various grades of gold purity, determined by the ratio of their alloy composition and rated by a karat system. Typical karat purities range from 10 karats to 24 karats (pure gold), with a wide variation of usage from country to country. In the United States, the most popular composition is 14 karat gold.

24 Karat Gold

In its purest form, the metal is comprised of 100% gold with virtually no alloy metals.
Pure gold is extremely soft and pliable, which is why it's often mixed with other metals, such as copper and silver, to forge jewelry.

22 Karat Gold

This level of gold is 91.7% pure which is still too soft to make jewelry and not as durable as 18K or 14K.

18 Karat Gold

This alloy consists of 75% gold and 25% alloy metals. 18 karat gold has been found to be the perfect balance between gold purity and strength.
Brilliance offers a variety of exquisite 18 karat gold jewelry.

14 Karat Gold

14 karat gold is 58.3% pure gold; the remainder is comprised of alloy metals.
Any gold purity less than 14 karat gold is not recommended for high quality jewelry.

10 Karat Gold

This tier of the metal consists of 41.7% gold.
This is the minimum purity that can still be considered gold in the United States and is not used for high quality jewelry.


Some countries use a required hallmarking system to imprint each gold jewelry piece with the karat count. Hallmarks for gold will typically appear as the karat weight (for example, 18 or 14) followed by 'K', 'KT', or 'karat'. Although this is not a government-mandated law in the United States, Brilliance stamps each piece of gold jewelry with the karat weight as a means of ensuring a confident, informed jewelry shopping experience.
Colors of Gold

Due to its inherent softness and malleability, gold is rarely used alone when forging a jewelry piece. Instead, it's blended with other fine metals to lend more hardness and durability. When pure gold is combined with these other metals, it takes on a variety of rich shades that have become desirable in their own right. At Brilliance, we offer an assortment of contrasting hues in our fine gold jewelry:

Yellow Gold

The most popular shade of the precious metal, gold is used to create a majority of the fine jewelry on the market today, especially yellow gold engagement rings and wedding bands.
It gets its warm, lustrous hue from the silver and copper alloys with which it's mixed. Within the yellow gold family, there can be a marked difference in shading based on the karat weight-for instance, an 18 karat yellow gold ring will be richer and more brilliant in color than one measuring 10 karats.
White Gold

Another popular choice for engagement and wedding rings, white gold gets its gleaming silver hue from the addition of alloy metals, including palladium, zinc, copper, tin, and manganese. The highest quality of white gold jewelry is generally 18 karats, consisting of a mixture of pure yellow gold and palladium.
At Brilliance, we coat each of our white gold pieces with a protective plating of Rhodium, a gleaming, near-white metal coating that's comparable in appearance to platinum. White gold can be re-dipped in Rhodium periodically to help maintain its original luster.

Rose Gold

Often heralded as a romantic metal, rose gold gets its striking coloration from the addition of copper and silver.
The larger the ratio of copper, the darker the rose coloration will be. Referred to as 'crown gold,' the most precious rose gold has a 22 karat weight. The more common 18 karat rose gold is comprised of 25% copper and 75% gold.
