What Does 18k Gold Plated Mean?
Definition:
18k gold-plated jewelry refers to items with a thin layer of 18-karat gold applied to the surface of a base metal. The base metal such as copper brass or sterling silver is usually less expensive. The gold layer is typically applied through electroplating which uses an electric current to bond the gold to the base metal.
Composition:
The “18k” in 18k gold-plated indicates that the gold layer comprises 75% pure gold with the remaining 25% composed of other metals like copper or silver. This composition gives the jewelry its characteristic rich yellow hue.
How is 18k Gold Plated Jewelry Made?
Electroplating Process:
The most common method for creating 18k gold-plated jewelry is electroplating. The base metal is submerged in a solution containing gold ions in this process. An electric current is then passed through the solution causing the gold ions to bond to the surface of the base metal.
Thickness of the Gold Layer:
The thickness of the gold layer can vary but it is generally fragile, often between 0.5 to 2.5 microns. This thin layer makes gold-plated jewelry more affordable than solid gold jewelry.
Benefits of 18k Gold Plated Jewelry:
Affordability:
One of the main advantages of 18k gold-plated jewelry is its affordability. The cost is significantly lower because the gold layer is thinner than solid gold jewelry.

While not as durable as solid gold, 18k gold-plated jewelry is more resistant to tarnishing and wear than lower-karat gold plating. The base metal also adds to its overall strength.
Drawbacks of 18k Gold Plated Jewelry:
Limited Lifespan:
The thin layer of gold can wear off over time, especially with frequent use. This means 18k gold-plated jewelry may not last as long as solid gold pieces.
Sensitivity to Chemicals:
Gold-plated jewelry can be sensitive to chemicals found in lotions perfumes and cleaning agents. These substances can cause the gold layer to tarnish or wear off more quickly.
How to Care for 18k Gold-Plated Jewelry?
Cleaning:
