Does Gold Tarnish?

Yes, gold will tarnish over time. However, gold is a very stable metal and does not tarnish as easily as other metals such as silver. Different purities of gold have different degrees of oxidation. Pure gold (24 karat) is highly resistant to tarnishing due to its low reactivity. However, pure gold jewelry is easily damaged due to its high malleability. Therefore, most gold jewelry is not pure gold. It's often alloyed with other metals such as silver, copper, or nickel to increase its durability and affordability, but is more susceptible to tarnishing over time.

What Does Tarnished Gold Look Like?

Tarnished gold often looks dull, less vibrant, and loses its natural luster.

Dull and lackluster: The once bright and reflective surface becomes dull and less vibrant.
Oxidation blackening: Tarnish can cause the gold to appear darker, also called discoloration, sometimes with a greenish or brownish hue, especially in lower karat gold, such as 10-karat or 9-karat gold.
Spotting: Small, darker patches may appear on the surface of the gold, breaking up its uniform color.

Why Does Gold Tarnish?

Gold itself does not react with oxygen or moisture in the air, so it does not oxidize or corrode like other metals. However, impurities or other metals that may be present in the gold alloy, such as copper or silver, can chemically react with the environment, such as chlorine in swimming pools, sulfur in the air, or certain cleaning products, and cause tarnishing or discoloration. Other causes, such as skin oils and perspiration, can also cause gold to tarnish. These factors can react with the alloy metals in gold jewelry, causing discoloration.

Does 14K Gold Tarnish?

Yes, 14k gold can tarnish over time. 14k gold is an alloy containing 58.5% pure gold and 41.5% other metals such as copper and silver. The gold content in 14k gold cannot tarnish, but the metal alloys can. While 14k gold is more durable and scratch-resistant than higher-purity gold, it is still possible for it to tarnish if not properly cared for. Tarnish on 14k gold can appear as a dull or discolored film on the surface of the metal, affecting its luster and shine.

Does 18K Gold Tarnish?

Similar to 14k gold, 18k gold can tarnish or become dull over time. But it's less likely to tarnish than lower karat gold, including 14k or 10k. 18K gold contains 75% pure gold. The remaining 25% is typically composed of other metals such as copper, silver, or nickel. These metal alloys are added to increase the durability and strength of the gold, since pure gold is quite soft but can react with environmental factors and skin oils, causing tarnishing.

Does 24K Gold Tarnish?

24K gold, also known as pure gold, which is 99.9% pure gold, does not tarnish easily because gold is a very stable and inert metal that does not react with oxygen or moisture in the air. But there is a possibility of tarnishing over time. However, because of its softness and malleability, it's often not used for everyday jewelry. It's more commonly used in investment-grade gold bars and coins.

Is Tarnished Gold Fake or Gold Plated?

Tarnished gold is not necessarily fake or plated. Tarnish can occur on both real gold and gold-plated gold. While it's true that gold-plated jewelry or fake gold often tarnishes quickly, even real gold jewelry, whether it's 24k, 18k, 14k, or another karat purity, will tarnish over time if not properly cared for. This is because these gold alloys contain other metals, such as copper or silver, that are more prone to oxidation and tarnishing. Gold-plated items have a thin layer of gold applied to a base metal through a plating process. When the gold plating wears off or tarnishes, it can expose the underlying base metal, giving the appearance of tarnished or discolored gold.

Gold Vermeil vs. Gold Plated

Gold vermeil and gold-plated jewelry are both made by applying a thin layer of gold over a base metal. Gold-plated jewelry can tarnish quickly compared to 14k gold jewelry. Can gold vermeil tarnish too? Yes, gold vermeil can tarnish, but it's less likely to tarnish than gold-plated jewelry. Gold vermeil has a layer at least 2.5 microns thick and the base metal is sterling silver. This makes it more durable and longer lasting than regular gold-plated jewelry. However, it's still susceptible to tarnishing.

How to Remove Tarnish from Gold?

Have you ever lamented the tarnishing of your beloved gold jewelry? Don't worry! You can easily remove the tarnish! Here are a few common but effective methods:

1. Use Soap and Warm Water

Soap is a common item in your home. Use a container to fill with warm water and mild dish soap. Then soak your gold jewelry in the solution for 15-20 minutes. Then use a soft-bristled brush or cloth to gently scrub away the tarnish.

2. Use Baking Soda and Water

Baking soda is also a common item in your home. Mix baking soda with a little water to make a paste. Apply the paste to the tarnished areas of the gold item and let it sit for a few minutes. Then gently scrub the paste onto the tarnish until it begins to lift.

3. Use Lemon Juice or White Vinegar

The principle of this method is to use acid to dissolve the tarnish. Soak your tarnished gold jewelry in a bowl of lemon juice or white vinegar for 15-20 minutes. Then gently scrub away any remaining tarnish with a soft-bristled toothbrush.

4. Use a Commercial Jewelry Cleaner

You can purchase a commercial jewelry cleaner made specifically for gold. Then follow the manufacturer's instructions for cleaning and removing tarnish from gold jewelry.
