What is 18K Gold Plated Jewelry?

on Sep 08, 2023

Did you know there are a lot of metal choices for jewelry? This short blog post will explain the difference between plated jewelry, solid metal jewelry, 18k gold plated meaning, and more.

Explore the world of 18k gold plated jewelry and uncover the significance behind this popular choice for fine jewelry, fine-fashion jewelry, and other bespoke pieces.

What is ‘Gold Plated’ Jewelry?

Is 18k gold plated real? Gold plated jewelry uses a stable base metal (often brass or copper) coated with a thin layer of gold. Base metals commonly include brass, copper, and sterling silver. This thin gold painted layer offers all the luxury and beauty of solid gold for any jewelry piece, including earrings, bracelets, necklaces, chains, anklets, and rings. However, it is much more affordable because it is not "solid" or just made of gold.

Gold Plating Process

What is 18k gold plated? Gold plated jewelry is created by using an electroplating process. This outer layer of real gold coats the base metal, giving it a "gold" appearance, appearing visually similar to solid gold pieces.

The gold plating process involves electroplating a thin layer of gold onto the surface of a base metal object. Cleaning the item being plated throughout the process improves the outcome. Here are some of the general steps involved in the gold plating process:

1. Surface Preparation:  Cleaning the object before gold plating will result in an optimal smooth coat and rich shine, whether the coat has a fancy finish or a classic high polish. Carefully removing dirt, bacteria, debris, and contaminants and smoothing out design imperfections will give the gold coat a better surface to adhere to without looking lumpy, bumpy, uneven, or flaky.

2. Electrolyte Solution & Tank: An electrolyte solution frequently containing gold salts or gold chloride is used to serve as a source of the gold ions used in the plating process. The jewelry or other decorative object to be plated combined with pure gold (called the anode) is immersed in an electrolyte-filled tank. The object is connected to the cathode (negative electrode), and the pure gold anode is connected to the anode (positive electrode).

4. Electroplating Process: When an electric current is applied to the object, gold ions from the electrolyte solution are attracted to the surface of the object. This results in the formation of a thin layer of gold on the object as it bonds to the base metal as the electrolyte solution bonds to the base metal.

The thickness of this layer can be adjusted with various factors such as the current, plating time, and the concentration of gold ions in the solution.

5. Rinsing and Drying: The object is removed from the electrolyte solution and thoroughly rinsed to remove any excess chemicals left behind. This is after the desired thickness of the gold plating is achieved. Removing water spots will prevent tarnishing and other imperfections as it dries.

6. Finishing and Polishing: The gold-plated object may undergo additional finishing and polishing processes depending on the desired look and effect.

7. Top Coat: In some cases, a clear protective coating may be applied over the gold plating to provide additional durability and prevent tarnishing.

8. Quality Control: The final gold plated item is inspected for uniformity, quality, and adherence of the gold layer to the base metal.

18K Gold Plated Jewelry vs. 18K Solid Gold Jewelry

The main difference between 18K gold plated jewelry and 18K solid gold jewelry is the amount of gold content and how it is made. The following are some attributes for 18k gold plated jewelry and 18k solid gold jewelry:

18K Gold Plated Jewelry

Composition: Gold plated jewelry or vermeil is measured in microns. The gold layer on 18K gold plated jewelry is relatively thin, typically ranging from 0.5 to 3 microns (μm). The more microns, the thicker the plating, resulting in added durability, weight, and price.

The gold content in the plating is significantly lower, generally less than 1% of the total weight of the piece; the base metal, stones, and other embellishments make up the bulk of the item's weight and composition. The plating is the finishing touch/top coat, achieving the desired look and metal color.

18K Solid Gold Jewelry

Gold is a noble metal, or stable, and can be mixed with alloys allowing it to become malleable, resistant, and durable with the aid of other metals. On its own, 100% pure gold appears reddish, is very soft and susceptible to scratching. Alloys amplify its rich yellow tone, popular for many fine jewelry designs and decorative objects.

Composition: 18K solid gold jewelry is composed of only 18 karat gold with no base metals--it is on its own, not coated or painted to another base metal.

18k gold consists of 75% pure gold (18 parts pure gold out of 24) mixed with other alloying metals like copper, silver, or palladium. The gold content in 18K solid gold jewelry is 75% of the total weight, making it much higher in gold content compared to gold plated items.

Gold Plated Jewelry Maintenance Tips

How long does 18k gold plated last? Following these simple tips and tricks will extend the life of your gold plated jewelry. Remembering to take good care of any jewelry will keep it safe from getting destroyed or damaged.

Don't Get It Wet

Plated jewelry is not like solid gold and should not be immersed in water or other liquid substances. This may permanently damage, corrode, or fade the plating overlay. Avoid exposing your gold plated jewelry to water, including swimming, showering, and washing dishes.

Keep It in a Soft Pouch or Box

Storing gold plated jewelry in a soft pouch or a jewelry box with individual compartments keeps it away from damage or loss. Keeping it away from other jewelry and objects minimizes scratching and contact with the air, helping to maintain its shine.

Wash with a Mild Liquid Soap

When cleaning your gold plated jewelry, using a mild liquid soap diluted in lukewarm water will help keep it clean without damaging the top coat. Gently scrubbing the piece with a soft-bristle toothbrush or a soft cloth removes dirt and oils. Rinse thoroughly after cleaning and carefully patting dry with a clean, soft cloth will help retain its shine and beauty.

Replate from Time to Time

Gold plating on your jewelry may wear off due to regular use over time--it is known for fading or tarnishing with frequent use and enjoyment. Having it professionally replated by a jeweler when the plating becomes visibly worn or tarnished restores its original shine and rich gold color.
