Does Real Gold Tarnish? A Closer Look at Marks and Spots on Gold

Gold is a reliable investment because it is a physical asset that cannot quickly increase or decrease in value. Many people wonder if gold can deteriorate over time. While it is true that gold can develop markings or spots, these blemishes do not impact its value.

Understanding these markings ensures informed decisions when buying or selling gold. Consulting with a reputable bullion dealer in Perth or other trusted bullion dealers in Australia can provide valuable insights.

What Is Pure Gold?

Gold purity is a crucial factor when valuing gold coins and bars. It indicates the amount of pure gold present in the item and is often marked on it.

Pure gold is very soft and malleable. It is usually mixed with other metals to increase its durability, creating an alloy. Knowing the exact purity of a gold item is essential for accurate valuation, especially when buying or selling gold.

How Many Karats Is Pure Gold?

Pure gold is often referred to as 24-karat gold or 999.9 fine gold. However, it’s impossible to create 100% pure gold. The highest purity achieved was 999.999 fine gold, produced by the Perth Mint in Australia in 1957.

For investment purposes, gold bars must be at least 995 fine. The London Bullion Market Association sets the standards for gold bars, ensuring their quality and purity. Gold is also used to make jewelry and other gold products.

When buying gold, you can choose between gold coins and gold bars. Reputable bullion dealers in Australia can help you select the right gold products for your investment goals.

Does Pure Gold Tarnish?

Gold is a precious metal that is highly resistant to tarnish. However, gold items with a purity below 24 karats, such as 22-karat gold jewelry, can tarnish over time. This is because these items often contain other metals like copper or zinc, which can react with elements in the air, causing discoloration.

Due to its high purity, pure 24-karat gold is less likely to tarnish. However, it can still develop marks and spots over time, especially if not adequately cared for.

If you are interested in buying gold, whether coins or bars, it is essential to purchase from a reputable bullion dealer in Australia, such as a Perth Bullion Exchange. This ensures that you are getting high-quality gold products.

When you are ready to sell your gold, working with a trusted dealer can help you get the best possible price for your investment.

A Closer Look at Marks and Spots on Pure Gold

To understand the intricate details of gold, let's examine the marks and spots on it closer.

Red Spots

Red spots are minor, reddish-brown marks that can sometimes appear on the surface of pure gold bars and coins. Impurities in the gold often cause these spots.

Common Causes of Red Spots:

• Copper Impurities: Traditionally, it was believed that even in 99.99% pure gold, trace amounts of copper could exist. When exposed to air, this copper can react with oxygen, forming reddish-brown spots.
• Silver Impurities: Recent studies have shown that silver impurities can also contribute to the formation of red spots. These silver impurities can react with sulfur in the air, discoloring the gold surface.

While these spots might be unsightly, they do not significantly impact the gold's purity or value. However, it is essential to consult with a reputable bullion dealer to get accurate information and advice on gold investments.

Toning

Toning is a natural process that can affect the appearance of gold coins. It occurs when a coin's surface is exposed to air, causing it to change color from bright yellow to orange or other hues. While toning cannot be entirely prevented, it is essential to note that it does not necessarily diminish a coin's value.

Some collectors prefer toned coins due to their unique appearance. For example, the Vespasian Aureus, a rare ancient Roman coin, exhibits a distinctive purple and blue toning caused by its burial in Pompeii.

However, it is essential to remember that most gold coins, such as modern gold bars or coins from the Perth Mint, do not typically develop such dramatic toning.

How Do These Marks and Spots Affect Your Investment?

You may notice marks or spots on the surface when investing in gold coins or bars. These are entirely normal and do not affect the value of your gold. They are a natural part of aging and occur in all precious metals.

While the number or size of these marks may increase, the gold remains unaffected. Pure gold does not decay or deteriorate.

Care Tips for Your Gold

Avoid opening their sealed packaging to protect the value of your gold coins and bars. Additionally, cleaning these items yourself can damage their surface, reducing their value.

However, there may be times when you need to handle your gold. If so, follow these guidelines to minimize the risk of damage:

Wear Protective Gloves

Wear cotton, lint-free gloves to prevent transferring oils and dirt when handling your gold. Avoid using latex gloves, as they can damage the metal's surface.

Minimize Handling

Limit the time your gold is exposed to air and human contact. Frequent handling can lead to scratches and other imperfections, reducing its value.

Store Properly

Store your gold in a cool, dry, and airtight container. Avoid storing it near other metals, especially silver, as this can lead to tarnish and corrosion. By following these guidelines, you can ensure that your gold investment remains in pristine condition.

Conclusion

Understanding the nature and potential markings of gold is crucial for any investor. While gold is inherently resistant to tarnish, minor imperfections like red spots and toning are natural occurrences and do not significantly impact its value.

Handling and storing your gold investment carefully and properly ensures its long-term preservation. Following these guidelines and consulting with reputable bullion dealers in Australia, you can safeguard your precious metal holdings and make informed investment decisions.
