Does 18k Gold Scratch Easily?

The allure of gold has captivated humanity for centuries, symbolizing wealth, luxury, and elegance. Among the various gold alloys, 18k gold stands out as a popular choice for jewelry due to its balance of purity and durability. However, a common concern among jewelry enthusiasts is whether 18k gold scratches easily. In this article, we will delve into the properties of 18k gold, explore its susceptibility to scratching, and provide insights to help you maintain the beauty of your precious pieces.


Understanding 18k Gold: Composition and Properties

Before addressing the scratching propensity of 18k gold, it’s crucial to understand its composition. 18k gold is an alloy comprised of 75% pure gold and 25% other metals, typically copper, silver, or palladium. The addition of these metals not only enhances the gold’s durability but also influences its color and hardness.


The term “karat” is used to measure the purity of gold, with 24k gold being the purest form. Therefore, 18k gold is considered relatively pure compared to lower karatages like 14k or 10k. However, this higher purity also means that 18k gold is softer and more malleable, which leads to the question: does 18k gold scratch easily?

Scratching Resistance of 18k Gold: Myth or Reality?

Contrary to common misconceptions, 18k gold is not immune to scratching. While its higher gold content provides greater resistance compared to lower karatages, it is still susceptible to abrasions, particularly in everyday wear. The hardness of gold alloys is measured on the Mohs scale, where pure gold ranks at around 2.5 to 3, while 18k gold typically falls within the range of 2.5 to 4. Therefore, while 18k gold is relatively durable, it is not impervious to scratches.

Various factors contribute to the scratching of 18k gold jewelry. Everyday activities such as handling objects, contact with hard surfaces, or exposure to abrasive materials can cause fine scratches to develop over time. Additionally, the presence of other metals in the alloy, such as copper or silver, can affect its hardness and scratch resistance.

Protecting Your 18k Gold Jewelry: Tips for Maintenance

While 18k gold jewelry may exhibit some susceptibility to scratching, proper care and maintenance can mitigate these concerns and preserve its beauty for generations to come. Here are some tips to help you protect your precious pieces:

Regular Cleaning: Keep your 18k gold jewelry clean by gently wiping it with a soft cloth after each wear to remove dirt, oils, and debris. Periodic cleaning with mild soap and warm water can help maintain its luster without causing damage.

Avoiding Harsh Chemicals: Refrain from exposing your 18k gold jewelry to harsh chemicals such as chlorine, bleach, or abrasive cleaners, as they can corrode or tarnish the metal and contribute to scratching.

Proper Storage: Store your 18k gold jewelry in a separate compartment or pouch to prevent scratching from contact with other pieces. Avoid storing it in humid or damp environments, as moisture can accelerate tarnishing.

Regular Inspections: Periodically inspect your 18k gold jewelry for signs of wear, such as scratches, dents, or loose stones. Promptly address any issues by seeking professional repair or maintenance to prevent further damage.

Avoiding Rough Activities: Remove your 18k gold jewelry before engaging in rough or strenuous activities, such as sports or manual labor, to minimize the risk of scratching or damage.

Professional Maintenance: Consider having your 18k gold jewelry professionally cleaned and polished by a jeweler periodically to restore its shine and remove any surface imperfections.

By following these simple yet effective maintenance practices, you can ensure that your 18k gold jewelry remains beautiful and pristine for years to come, despite its susceptibility to scratching.


In conclusion, while 18k gold is prized for its beauty and purity, it is not immune to scratching. Despite its relatively higher resistance compared to lower karatages, 18k gold jewelry can develop scratches over time due to everyday wear and exposure to abrasive materials. However, with proper care and maintenance, you can minimize the risk of scratching and preserve the luster and elegance of your precious pieces. By following the tips outlined in this article, you can enjoy your 18k gold jewelry for generations to come, debunking the myth that it scratches easily.
