  4. Care of Gold Jewelry

Gold is a very durable and desirable metal that does not rust, corrode, or tarnish over time or with wear and tear. Throughout the ages, all over the world, Gold has been used by jewelers as much as for its beauty as for its ease of use. Gold is extremely malleable, and can be melted and shaped to create any design. Because of this extreme malleability, Gold in its purest form is not suitable for jewelry as it would not be able to withstand the rigors of daily wear and tear. It is therefore alloyed with other metals to make it stronger and more suitable for making jewelry.

Gold Terminology

The Gold content in a metal is measured in terms of karats (“k” or “kt”). Pure Gold or 100% Gold is referred to as 24k Gold. When this pure Gold is alloyed with other metals, such as silver, copper, or nickel, the Gold percentage decreases. 18k Gold is 18/24th or 75% pure Gold, and 14k Gold is 14/24 or 58.3% pure Gold. As the percentage of pure Gold decreases, the strength of the metal increases: so 14k Gold is stronger than 18k Gold. Additionally, as the percentage of pure Gold decreases, the price of the metal also decreases: so 14k Gold will cost less than 18k Gold.

Gold Karat Chart

24 karat Gold equals 100% pure Gold too soft for jewelry
22 karat Gold equals 91.7% Gold still too soft for jewelry. Popular in certain parts of the world.
18k Gold equals 75% Gold very popular for jewelry, good balance of strength and value
14 karat Gold equals 58.3% Gold extremely popular for jewelry. Good balance of durability and value.
12 karat Gold equals 50% Gold not used for jewelry
10 karat Gold equals 41.7% Gold lowest Gold content that can be legally marked as Gold in the United States.

To determine the karat weight of a piece of jewelry, look for the markings on the jewelry. In the United States all Gold jewelry will be marked with its karat weight, designated by 24k, 18k, 14k etc. In Europe, jewelry is marked by a number which is the percentage of Gold in the alloy, for example 18k is marked “750” to designate the 75% of Gold in the metal.

Colors of Gold

Yellow Gold

Gold has a warm yellow color in its purest form. Even when it is alloyed with other metals such as silver, nickel or palladium to make 14k or 18k Gold, it retains a yellowish color. The richness of the Gold color is directly affected by the percentage of Gold in its alloys: therefore, 18k Gold has a richer Gold color than 14k Gold.

White Gold

To give White Gold its brilliant shiny white luster, the final process of making White Gold involves plating the metal with a layer of Rhodium. Rhodium is a shiny white metal, which is extremely hard and durable. Over time, with regular wear, the Rhodium plating may wear off revealing the yellow Gold underneath, and can be easily repaired by a jeweler who can redo the Rhodium plating.

Rose Gold

When Gold is alloyed with a high percentage of Copper, the presence of Copper gives the alloy a pinkish tint. This alloy has popularly come to be known as Rose Gold.

Price of Gold Jewelry

In addition to the karat weight, several other factors determine the price of Gold jewelry. These factors include, but are not limited to, total weight of the jewelry, design and construction, and ornamental detailing such as engraving and the finish of the metal. Although nearly all Gold jewelry today is made with the help of special machines, some hand work is almost always involved, and the more hand work that is involved, the higher the price.

Care of Gold Jewelry

It is very important to take proper care of your Gold jewelry to maintain its beauty. It is advisable to remove all jewelry during rugged activities. Gold jewelry can be very easily cleaned, by soaking it in a mild soapy solution and scrubbing it very gently with a soft bristled brush. Try to always store your Gold jewelry in an individual or compartmentalized fabric lined case as this will prevent any unnecessary scratching. Check the prongs of your jewelry regularly, and always show your jewelry to a professional if you notice any loose prongs.
