Which Gold Doesn’t Tarnish | What Does Tarnished Gold Look Like?

Gold is a precious metal that is prized for its beauty and durability. However, even gold can tarnish over time. Tarnishing is the process by which gold develops a dull, discolored appearance due to exposure to environmental factors such as air, water, and chemicals. This article will explore the causes of tarnishing in gold, what tarnished gold looks like, and how to clean and care for your gold jewelry to prevent tarnishing.

Why Does Gold Tarnish

Pure gold, or 24-karat gold, is resistant to tarnish because it is a noble metal that doesn’t react with air or water. However, most gold jewelry is made from alloys, combining gold with other metals such as copper, nickel, or silver. These metals can oxidize over time, leading to tarnishing.

Factors contributing to tarnishing include:

• Exposure to chemicals: Lotions, perfumes, hair sprays, and household cleaning products can lead to tarnish, especially if they come into contact with gold jewelry.
• Moisture and humidity: Frequent exposure to water, especially chlorinated water, can accelerate tarnishing in gold jewelry, particularly if it contains lower karats.
• Body oils and sweat: Oils produced by the skin, along with sweat, can react with the alloys in gold, leading to tarnish.

Are Tarnished Gold Rings Fake?

One of the first questions many people have when they see tarnished gold is whether or not it is real. The truth is that even real gold can tarnish, so a tarnished gold ring does not necessarily mean it is fake. Gold is a naturally occurring element found in nature and is the most malleable and ductile of all metals. It is also resistant to corrosion, which is why it has been used for jewelry and other decorative items for thousands of years.

However, it is important to note that some gold-plated or gold-filled items on the market may appear tarnished but show signs of wear on the gold plating. You can perform a simple acid test to determine if a gold ring is real. Gold will not react to acid, whereas other metals will.

How Do I Clean Tarnished Gold?

If you have a piece of gold jewelry that has become tarnished, there are several ways to clean it and restore its shine. The first step is gently brushing the piece with a soft-bristled toothbrush to remove dirt or grime. Then, you can use mild soap and warm water to gently clean the piece. Rinse the jewelry with clean water and dry it with a soft cloth.

Another option for cleaning tarnished gold is to use a commercial jewelry cleaner. These cleaners are specifically designed for gold and other precious metals and can be found at most jewelry stores or online. Be sure to read the instructions carefully and follow them exactly to avoid damaging your jewelry.

Common Causes of Tarnishing

There are several common causes of tarnishing in gold jewelry. One of the most common is exposure to air, which can cause a buildup of sulfur and other pollutants on the surface of the gold. This can happen even if you are not wearing the jewelry, as air pollution can cause tarnishing even when the jewelry is stored in a safe place.

Another common cause of tarnishing is exposure to water. Gold is not water-soluble but can be affected by minerals and other impurities in water. This can cause discoloration and dullness in the gold.

Chemicals can also cause tarnishing in gold. This includes perfumes, lotions, and hair care products that contain chemicals that can react with the gold. In addition, exposure to chlorine and other chemicals can cause tarnishing in gold.

What Does Tarnished Gold Look Like?

Tarnished gold typically looks dull and discolored. The color of tarnished gold can range from yellow to black, depending on the severity of the tarnishing and the type of pollutants that have come into contact with the gold. In some cases, tarnished gold may have a greenish or bluish tint, caused by a buildup of copper on the surface of the gold.

Tarnished gold may also have a rough or grainy texture, caused by the buildup of microscopic crystals on the surface of the gold. These crystals can make the gold appear dull and cloudy.

Does Real Gold Turn Black?

One of the most common questions about tarnished gold is whether or not real gold can turn black. The short answer is yes, real gold can turn black. However, it is important to note that this is not a common occurrence and is usually caused by specific circumstances.

Additionally, one of the most common causes of black tarnishing in gold is exposure to sulfur. Sulfur is present in the air and can cause a reaction with the gold, creating a black coating on the surface of the gold. This type of tarnishing can be removed by cleaning the gold with mild soap and warm water or using a commercial jewelry cleaner specifically designed for gold.

Another cause of black tarnishing in gold is exposed to chlorine. Chlorine is often found in swimming pools and hot tubs and can cause a reaction with the gold, turning it black. This type of tarnishing can be removed by cleaning the gold with mild soap and warm water or using a commercial jewelry cleaner specifically designed for gold.

Home Remedies for Cleaning Tarnished Gold

For most cases of tarnish, you can clean your gold at home using simple methods. These methods are particularly helpful for lightly tarnished gold. Below are a few common techniques.

Dish Soap and Warm Water

This is one of the safest and simplest methods for cleaning tarnished gold.

• Mix a few drops of mild dish soap with warm water in a small bowl.
• Soak the gold in the solution for about 15 minutes.
• Gently scrub the gold using a soft-bristle toothbrush, paying extra attention to crevices.
• Rinse the gold under warm water and dry it thoroughly with a soft, lint-free cloth.

This method works well for light tarnishing, especially on gold chains, rings, and earrings. Dish soap is gentle enough not to harm gold or its alloys but strong enough to remove oils and dirt.

Baking Soda and Water Paste

Baking soda is an effective cleaner for tarnished gold but should be used carefully.

• Make a paste by mixing two tablespoons of baking soda with a small amount of water.
• Apply the paste to the tarnished gold and gently rub it with your fingers or a soft cloth.
• Rinse thoroughly with warm water and dry with a clean cloth.

This method should be used cautiously on gold-plated jewelry, as over-scrubbing may remove the gold layer. Avoid baking soda on soft gemstones like pearls, as it can scratch their surfaces.

Ammonia Solution

Ammonia can effectively clean heavily tarnished gold, but it must be used cautiously.

• Mix one part ammonia with six parts water in a bowl.
• Soak the tarnished gold in the solution for no longer than one minute.
• Remove the gold and rinse it thoroughly with water.
• Dry the gold immediately with a soft cloth.

Because ammonia is a strong chemical, it should only be used occasionally. Frequent exposure can damage gold jewelry, particularly those with gemstones.

Vinegar and Salt Solution

Another common household method for cleaning gold involves vinegar and salt.

• Mix one cup of vinegar with one teaspoon of salt.
• Submerge the gold in the solution for about five minutes.
• Rinse thoroughly with water and dry with a soft cloth.

This method works well for pieces of gold jewelry without delicate gemstones, as vinegar is acidic and may affect certain stones.

How to Maintain and Protect Gold from Tarnish

Once you’ve cleaned your gold, there are a few things you can do to maintain its shine and prevent future tarnish.

Proper Storage

Store your gold in a cool, dry place. Keep each piece in a separate soft cloth or a lined jewelry box to prevent scratches and exposure to air and moisture.

Limit Exposure

Avoid wearing gold jewelry when swimming in chlorinated pools, using cleaning chemicals, or applying lotions, perfumes, or hairspray. These substances can cause tarnish and discoloration.

Regular Cleaning

Clean your gold regularly using mild soap and water. You don’t have to wait to clean it until it is heavily tarnished. Regular maintenance can keep it looking shiny and new.

Wear Gold Often

Believe it or not, wearing your gold jewelry often can help prevent tarnish. The natural oils from your skin can protect gold and keep it shiny.

Is Professional Cleaning Necessary?

While it’s possible to clean tarnished gold at home with readily available household items, there are certain cases where professional cleaning is a better option. If your gold is heavily tarnished or contains delicate gemstones, taking it to a jeweler can ensure that it’s cleaned safely and effectively.

Cleaning tarnished gold doesn’t have to be a difficult task. Whether you opt for simple home remedies like soap and water, or more intensive methods like ammonia and vinegar solutions, you can restore your gold’s brilliance and keep it looking new. Just be sure to avoid common cleaning mistakes and take care to maintain your gold jewelry regularly.

In conclusion, tarnishing is a natural process that can occur in gold jewelry over time. However, with proper care and cleaning, you can prevent tarnishing and keep your gold jewelry looking beautiful for years to come. Tarnished gold does not necessarily mean that the gold is fake; tarnishing can be caused by various environmental factors such as air, water, and chemicals. Tarnishing can be removed by cleaning the gold with mild soap and warm water or using a commercial jewelry cleaner specifically designed for gold. Remember that real gold can turn black, but it’s not a common occurrence and can be removed. If you have doubts about your gold jewelry’s authenticity, it’s always best to consult a professional jeweler.
