Does Chlorine Damage Gold: The Truth About Wearing Gold in the Pool

Summer has arrived, and it’s time to dive into the refreshing blue waters of the swimming pool. For many, this season is synonymous with relaxation, laughter, and flaunting stylish accessories – including beautiful gold jewels. The shimmering allure of gold has enchanted humans for millennia, and many of us wear our gold jewelry with pride, even in the water. But a nagging question persists in the minds of many gold enthusiasts: Does chlorine, a common chemical found in swimming pools, damage gold? Is it safe to wear your beloved jewelry as you enjoy a swim?

In this post, we’ll walk you through the definitive answer on whether you should be wearing your gold jewelry the next time you take a plunge. So before you jump in, take a moment to read on.

Understanding the Impact of Chlorine on Gold

Chlorine is a highly reactive substance, often used in pools to kill bacteria and keep the water clean. On the other hand, gold is renowned for its stability and resistance to corrosion. However, when gold is mixed with other metals to create various alloys, as is common in pieces of jewelry, the situation becomes more complex. Chlorine can react with these other metals, causing discoloration and structural damage. The purer the gold (such as 24-karat gold), the less likely it is to be affected by chlorine. But lower karats of gold, containing metals like copper or silver, may be more vulnerable. That’s why understanding the specific composition of your gold jewelry and the chlorine concentration in the pool can be vital to preserving its shine and integrity.

What Does Chlorine Do to Gold?

Even in ancient times, gold is often regarded as a timeless symbol of wealth, beauty, and elegance. However, most gold jewelry is not pure gold. Instead, it’s often mixed with other metals like copper, silver, or nickel to make it more durable since gold is a soft metal. These alloys in gold can be more susceptible to reactions with chlorine, especially when the karat value is lower.


To improve durability and malleability, gold is combined with other metals such as copper, silver, or nickel, creating what is known as an alloy. When you wear them in swimming pools, chlorine, a potent oxidizing agent, can react with these alloyed metals, leading to potential discoloration. Specifically, metals like copper can oxidize in chlorine, forming a greenish patina. Similarly, silver in the alloy can tarnish, turning blackish. While the gold remains essentially inert, the reaction of chlorine with these other metals can diminish the luster of the jewels and give them a discolored appearance.

Structural Damage

Chlorine’s corrosive effects on alloyed components of gold jewelry can gradually weaken the bonds between the molecules of base metals, causing them to break down. This not only leads to discoloration but also to the piece of jewelry becoming brittle. The structural integrity of the gold piece is compromised, making it more susceptible to cracks, bends, and breaks.

Damage Lower Karat Gold

The chlorine can oxidize these metals, leading to discoloration, tarnishing, and in some cases, corrosion. Additionally, the chemical reactions can undermine the structural cohesion of the jewelry, making it brittle or prone to defects. Therefore, the impact of chlorine is especially pronounced on lower karat gold, as its increased content of other reactive metals amplifies the potential for damage and deterioration.

Can you wear gold in the pool?

Pure gold is chemically inactive and resistant to most external agents, including chlorine. However, most gold jewelry isn’t pure gold but is a mix of gold and other metals. These alloys, especially in lower karat gold pieces, can react with chlorine in swimming pools. This chlorine exposure can lead to discoloration, tarnishing, and even structural damage over time. So, while an occasional dip in your gold jewelry might not lead to immediate harm, frequent and prolonged exposure can have detrimental effects.

Potential Risks Of Wearing Gold Jewelry While Swimming

While swimming, especially in chlorinated pools, the chemicals can react with the alloyed metals in your gold jewelry, leading to discoloration or tarnishing. The salty composition of seawater can similarly affect the jewelry’s luster. 

Additionally, the physical act of swimming, with its rapid and forceful movements, increases the chance of snagging, bending, or losing a piece. There’s also the concern of sunscreen, lotions, and natural body oils, which, when combined with water, might coat the piece of jewelry, causing it to lose its brilliance.

Practical Tips To Protect Gold Jewelry From Chlorine Damage

The most straightforward precaution is to remove your jewels before entering a pool, hot tub, or any chlorinated water source. If you forgot to take it off, rinse it immediately afterward with fresh, warm water. This can help remove residual chlorine before reacting with the alloyed metals.

It would be best to clean your gold chains regularly using a mild soap and water solution. Gently scrubbing with a soft-bristle brush can help remove any chlorine deposits and maintain the jewelry’s shine. When not in use, especially after exposure to chlorine, store your gold pieces separately in a jewelry box lined with a soft cloth. This prevents them from scratching against each other and reduces the chance of bleach residues affecting multiple parts.

If you notice any signs of discoloration, tarnishing, or structural weakness, consult a qualified jewelry appraiser. They can provide advice or treatments to restore your precious metal’s appearance and strength. Some jewelers offer protective coatings that can act as a barrier against potential chemical reactions. While rare for high-end pieces, this might be an option for items you wear for an entire time.

Types Of Jewelry Suitable For Pool Activities

It’s essential to look for materials that can withstand the chemicals in the water. Here are some of your options:

Stainless Steel

This material is known for its durability and rust, tarnish, and corrosion resistance. Stainless steel jewelry can retain its shine even after repeated exposure to pool water.


Silicone bands and rings are becoming popular, especially for active individuals. They are non-reactive, waterproof, and offer a snug fit, making them an excellent choice for water activities.

Synthetic Gemstone

While genuine gemstones might react or degrade over time in chlorine, synthetic or lab-created stones, such as simulated diamonds, tend to be more stable and less prone to damage in pool water.

How do you fix chlorine-damaged gold jewelry? 

Rinse the affected jewelry immediately in lukewarm water to remove lingering chlorine residues. Next, mix a few drops of dish soap with warm water to prepare a gentle cleaning solution. Using a soft-bristle brush, gently scrub the jewels, paying attention to crevices or areas where discoloration is pronounced. After cleaning, rinse thoroughly with clean water and pat dry with a soft, lint-free cloth.

If the damage has affected the structural integrity of the jewels or if discoloration persists, it’s advisable to visit a gold jewelry appraisal. Depending on the extent of the damage, they can offer specialized treatments, polishing, or re-plating services to restore the jewelry’s original luster and strength.
