So, if you’re curious about the markings on your gold jewelry, read on to discover more about decoding the stamp 800 and other popular gold jewelry markings.

The Basics of Gold Jewelry Markings

The karat weight of the gold is the most important marking, and it indicates the percentage of gold in the jewelry. Pure gold is 24 karats, and it is too soft for daily wear, so it is often combined with other metals to make it more durable. Common karat weights for gold jewelry in the United States are 10k, 14k, and 18k.

When looking at the manufacturer’s mark, you may see an abbreviation, a symbol, or the full name of the company. This marking helps identify the maker of the jewelry and can give insight into its value based on the reputation of the manufacturer.

Finally, the country of origin marking may help determine the gold’s value or authenticity. Some countries have strict guidelines for gold purity and manufacturing, so knowing the country of origin can be helpful in determining the quality of the gold jewelry.

What Does the Stamp 800 Mean?

The stamp “800” refers to the purity of the gold used in the jewelry piece. Specifically, it means that the gold is 80% pure. This level of purity is common in gold jewelry that is made in Italy, where the standard for gold purity is 18 karats or 75% pure. In other countries, the standard for gold purity may be different, which is why you may see different numbers or letters stamped on your gold jewelry.

If you’re wondering why gold jewelry isn’t always made with 100% pure gold, the answer is simple: gold is a soft metal that is prone to scratches and other forms of damage. By mixing other metals with gold, jewelers can create a more durable and long-lasting piece of jewelry that will stand up to daily wear and tear.

Overall, the stamp “800” is a reassuring symbol to see on your gold jewelry. It means that your piece is made with high-quality, durable materials that will last for years to come.

How to Identify Real Gold Jewelry

When buying gold jewelry it is important to know how to identify whether it is real or fake. Here are some tips to help you:

  • Look for a hallmark: Real gold jewelry will have a hallmark or stamp indicating the karat weight of the gold.
  • Check for discoloration: Fake gold jewelry may discolor and turn green or black over time because it is not made of real gold.
  • Do a magnet test: Real gold is not magnetic, so if your jewelry sticks to a magnet it is not made of real gold.
  • Perform a nitric acid test: This test involves applying a drop of nitric acid to your jewelry and observing the reaction. Real gold will not react, while fake gold will turn green or brown.
  • Consider the weight: Real gold jewelry will be heavier than fake gold jewelry of the same size and style.

By using these tips, you can confidently identify whether your gold jewelry is real or fake. Remember to always shop with a reputable jeweler and have your jewelry appraised if you are unsure of its authenticity.

Understanding the Purity of Gold

Gold jewelry is a popular choice to wear for special occasions and as an investment. The purity of gold is measured in karats, which indicates the percentage of pure gold in the piece. Understanding the purity of gold can help you differentiate between high-quality and lower-quality pieces, and make informed purchasing decisions.

Karat System

The karat system is used to describe the purity of gold. Pure gold is 24 karats (24K), meaning it is 100% gold. However, pure gold is too soft for jewelry and other applications, so it is alloyed with other metals to increase its strength and durability. This creates different karat values that reflect the percentage of gold in the item. For example, 18K gold is 75% gold and 25% other metals, while 14K gold is 58.3% gold and 41.7% other metals.

Hallmarks and Stamps

Gold jewelry is often stamped with hallmarks or stamps to indicate its purity. In the United States, the Federal Trade Commission requires that any jewelry labeled as gold must have a hallmark or stamp indicating its karat weight. The most common stamp for 14K gold jewelry is “585”, which means 58.5% gold. Other stamps include “14K” and “14KT”.

Gold Color

The purity of gold also affects its color. Yellow gold is the most common color for gold jewelry, and is created by combining pure gold with copper and silver. White gold is created by alloying pure gold with nickel, palladium, or silver. Rose gold is created by combining pure gold with copper.


Understanding the purity of gold is essential when purchasing gold jewelry or investing in gold. Knowing the karat weight of a piece can indicate its value, and the color of the gold can provide clues about its purity. By learning about the karat system and the common hallmarks and stamps used to indicate the purity of gold, you can make informed decisions about your gold purchases.

The Importance of Hallmarks and Stamps

Hallmarks and stamps are important markings found on gold jewelry that provide critical information about the piece. It is important to understand the significance of these markings to ensure that you are purchasing a high-quality piece of jewelry.


One of the most important reasons to pay attention to hallmarks and stamps is for authenticity purposes. These markings confirm that the jewelry is made of real gold and not a fake metal or gold plated. This is essential when you are investing in expensive pieces of jewelry that you want to last a lifetime.


The purity of gold is also indicated by hallmarks and stamps. This tells you what percentage of the gold is pure. The higher the percentage, the purer the gold. A stamp of 24k denotes that the jewelry is made of pure gold, while a stamp of 10k indicates that the jewelry is made of only 41.7% gold.

Maker’s Mark

The maker’s mark is another important hallmark that can indicate the origin of the piece. This is especially true for antique and vintage jewelry. Knowing the maker’s mark can help to prove the authenticity of the piece and can add value to it as well.

Overall, it is essential to understand the importance of hallmarks and stamps on gold jewelry. These markings provide information about authenticity, purity, and origin, all of which are critical pieces of information when purchasing and valuing gold jewelry.

Differences Between Gold Plated, Gold Filled, and Solid Gold Jewelry

Gold plated jewelry consists of a base metal, such as copper or brass, that is covered with a layer of gold. The thickness of the gold layer can vary, but it is typically very thin, around 0.05% of the total weight of the piece. Gold plated jewelry is the most affordable option, but the gold layer can wear off over time and will need to be re-plated.

Gold filled jewelry is made by bonding a thick layer of gold to a base metal, usually brass, using heat and pressure. The gold layer of gold filled jewelry must be at least 5% of the total weight of the piece. Gold filled jewelry is more durable than gold plated jewelry, and the gold layer will not wear off as easily.

Solid gold jewelry is made entirely of gold, which is why it is the most valuable and expensive option. The purity of the gold used in the piece is indicated by its karat value, with 24 karat being the purest form of gold. Solid gold jewelry is durable and will not tarnish, but it is also the most expensive option.

How to Care for Your Gold Jewelry

Gold jewelry is not only beautiful but also a precious investment that should be properly cared for to maintain its shine and value. Here are some tips on how to take care of your gold jewelry:

  • Avoid harsh chemicals: Chemicals like chlorine and bleach can damage your gold jewelry. It’s best to remove your jewelry before swimming or using any cleaning products.
  • Store properly: When you’re not wearing your gold jewelry, store it in a soft pouch or jewelry box to protect it from scratches and other damage. Avoid storing it with other jewelry that might scratch it.
  • Clean regularly: Over time, gold jewelry can accumulate dirt and oils from the skin. Clean your gold jewelry regularly with a soft cloth and mild soap and water. Dry it thoroughly before storing it away.
  • Avoid wearing during physical activity: Gold jewelry can be easily damaged or scratched during physical activity, so it’s best to remove it before exercising or doing any strenuous activity.

By following these simple tips, you can keep your gold jewelry looking shiny and new for years to come. Taking care of your gold jewelry is not only important for its appearance but also for preserving its value and investment potential.

Shopping Tips for Buying Gold Jewelry

Gold jewelry is a timeless and luxurious addition to any wardrobe. Whether you’re buying for yourself or someone else, there are a few things to keep in mind to ensure you’re getting quality pieces that will last for years to come.

Consider the Purity of the Gold

The purity of gold is measured in karats. 24 karat gold is 100% pure gold, but it is too soft for most jewelry. Commonly, 14kt (58% gold) and 18kt (75% gold) are used to make jewelry. When shopping for gold, pay attention to the karatage mark, which should be stamped on the piece. A quality gold piece should have a karatage mark, such as 14K or 18K, to indicate its purity.

Check the Weight and Size

Gold is denser than many other metals, so it should feel heavy for its size. If a piece of jewelry feels lightweight or hollow, it may not be well-made or may not be made of real gold. Additionally, consider the size of the piece. If it’s a ring, make sure it fits properly for comfort and wear. If it’s a necklace or bracelet, make sure the length is appropriate for the wearer.

Look for Quality Craftsmanship

Quality jewelry should be well-made and free from defects. Examine the piece for any weak spots or areas that may bend or break. Additionally, check clasps, earring backs, and other fastenings to make sure they work properly and securely. If possible, inspect the jewelry with a magnifying glass to ensure there are no scratches, dents, or other imperfections.

Compare Prices

Use a price comparison tool or visit different jewelers to compare prices on gold jewelry. Remember that the price of gold fluctuates, so be aware of current market trends before making a purchase. Additionally, keep in mind that higher karat gold will be more expensive than lower karat gold.

  • Consider the purity of the gold
  • Check the weight and size of the jewelry
  • Look for quality craftsmanship
  • Compare prices
