Guide to Identifying Gold Types in the Market Most Accurately

Gold is a precious rare metal that not only possesses high economic value but is also widely used in crafting high-end jewelry such as diamond gold rings, diamond gold earrings, diamond-studded gold necklaces, or diamond-studded gold bracelets. However, not all types of gold are the same. Each type of gold has its own unique characteristics, suitable for different purposes of use. Let's learn more with Jemmia Diamond in the following article. 

What is gold?

Gold is a rare chemical element, with the chemical symbol Au and atomic number 79. With its characteristic yellow color, high durability, and excellent corrosion resistance, gold has long been considered one of the most precious metals. These outstanding properties have made gold a valuable store of value or used as the setting for 18K gold diamond rings for women or luxurious diamond-studded gold jewelry.

Types of gold on the market today

The current gold market is very diverse with many different types of gold designed to meet all consumer needs. So, how many types of gold are there? Here are the popular types of gold on the market today: 

Pure Gold/9999 Gold/24K Gold

Pure gold is also known as 24K gold or 9999 gold. This is gold with a high purity of up to 99.99%, with an extremely small impurity content of 0.01%. Because of this, pure gold is the type of gold with the highest value among all types of gold. 

Pure gold has some outstanding characteristics that help you easily distinguish it from other types of gold, such as: 

• Usually cast into bars and ingots for long-term asset accumulation.
• Pure gold has a characteristic, unfading golden color.
• It is soft and difficult to process into jewelry.
• As it is rarely processed into jewelry, the designs of this type of gold are quite simple.
• Maintains stable value, rarely depreciates.
• High durability, little oxidation and wear. 

999 Gold

999 gold and pure gold (99.99%) have many similarities in properties and value. However, 999 gold has a slightly lower pure gold content than pure gold. 999 gold has a pure gold content of 99.9%, a characteristic bright yellow color, good durability, and high oxidation resistance. Therefore, 999 gold is mainly used for investment and accumulation.

Some outstanding characteristics of 999 gold that help you easily distinguish it from other types of gold: 

• Similar to pure gold, 999 gold is usually cast into bars and ingots for long-term accumulation. 
• Characteristic color, difficult to fade.
• High durability, little oxidation.
• Stable value over time.

White Gold/10K, 14K, 18K White Gold

White gold is still gold, but not natural gold. It is a precious alloy created by combining pure gold (usually 24K gold) with other precious metals like platinum, palladium, and nickel. During the refining process, the gold layer is replaced by a white metal layer, hence it is called white gold. 

Besides its characteristic white color, white gold also has high hardness and durability, overcoming the soft and malleable drawbacks of pure gold. Therefore, this type of gold is commonly used in jewelry making, creating expensive and luxurious jewelry designs.

How many types of gold are there? White gold has many different types, distinguished by gold content measured in karats. Specifically: 

• 10K white gold with a gold content of 41.67%.
• 14K white gold with a gold content of 58.33%.
• 18K white gold with a gold content of 75%.

Rose Gold/10K, 14K, 18K Rose Gold

Rose gold is an alloy created by mixing pure gold with copper. This combination creates a gentle, sweet, and luxurious rose gold hue, thus diversifying the styles and designs of jewelry. 

Rose gold also has different types such as 10K, 14K, 18K rose gold, each with its own pure gold content, specifically: 

• 10K rose gold contains 41.67% gold.
• 14K rose gold contains 58.33% gold.
• 18K rose gold contains 75% gold.

Yellow Gold/10K, 14K, 18K Yellow Gold

Yellow gold is a precious alloy created by combining pure gold with other alloys such as copper, silver, and nickel. Yellow gold also includes different types such as 10K, 14K, 18K based on the pure gold content: 

• The gold content of 10K yellow gold is 41.67%.
• The gold content of 14K yellow gold is 58.33%.
• The gold content of 18K yellow gold is 75%.

Unique characteristics of yellow gold: 

• Yellow gold has high hardness, so it is often used in jewelry making with highly aesthetic designs.
• Yellow gold comes in various colors depending on the mixture of gold with which metal. 
• Yellow gold can tarnish over time, so you need to bring it to a store for polishing.

Italian Gold

Italian gold is gold originating from Italy. Italian gold has a luxurious silver-white color due to the combination of high pure silver content with other metals. Italian gold jewelry is very popular thanks to its diverse designs combined with a bright, sophisticated silver-white color and affordable prices, meeting the needs of many customer segments.

What types of Italian gold are there? Currently, there are 2 types of Italian gold on the market: 750 Italian gold and 925 Italian gold, of which: 

• 750 Italian Gold (more common): Contains 75% pure silver and 25% precious metals. This type is suitable for jewelry making due to its good hardness.
• 925 Italian Gold: Contains 92.5% pure silver and 7.5% precious metals. This type of gold is soft, so it is not often used in jewelry making due to its high difficulty.

Low Purity Gold

Low purity gold is gold with a very low pure gold content, not suitable for asset accumulation. The gold content of this type of gold is often difficult to determine accurately, so its real value is not guaranteed. This type of gold has some easily recognizable characteristics: 

• Low gold quality, cheap price.
• Diverse designs, bright colors but easily tarnish over time.
• Easily counterfeited.
• Very low resale rate.

Gold Plated Jewelry (Vàng Mỹ Ký)

Gold plated jewelry, also known as double-layered gold, is made of a layer of real gold (18K or 24K) on the outside, with a core of low purity gold or cheap alloy inside. Due to this special construction, distinguishing gold plated jewelry from real gold becomes more difficult, posing a risk of purchasing products that are not worth their price. 

In addition to the two layers, gold plated jewelry also has some characteristics such as: 

• Finely crafted, attractive like real gold.
• Easily tarnishes after a period of use.
• Low price, meeting the needs of many users.
• Difficult to resell.

Markings for Gold Types

There are many markings for gold types, and each marking represents different information. Here are some common markings for gold types.

Gold Markings

Here is a table of information on popular gold markings today: 

Regulatory Markings: 

For products with a gold coating on a base of other metal or material, if the pure gold content is 1/40 of the total weight or more, the gold ratio must be clearly stated on the packaging. The accompanying markings are usually G.P or G.F, followed by the gold purity (e.g., 1/40 G.P 24K, 1/20 G.F 18K).

Markings by Gold Content: 

In addition to other information, gold rings and other gold products also have markings indicating the pure gold content on their surface. These markings help consumers easily identify the "age" of the gold, thereby assessing the value and quality of the product. Specifically, as follows: 

Markings for Logos, Company Names

In addition to mandatory information, engraving logos and brand names on products has become a standard for many businesses. This helps customers easily distinguish genuine products, protect consumer rights, and at the same time affirm the brand's position in the market. As a result, customers will have better shopping experiences, and businesses will also enhance customer trust.
