12 Types of Gold: All Colors & Karats Explained

There are 13 total types of gold recognized in jewelry and investing today: 8 distinct gold colors (yellow, white, rose, green, black, blue, purple, and gray) and 5 common gold karats (24k, 22k, 18k, 14k, and 10k) that measure purity. Color comes from the metals alloyed with pure gold, while karat measures how much actual gold is in the piece — the two systems work together, not against each other, to define any gold item's look, durability, and price.

Quick summary: Gold's color is created by blending pure gold with other metals like copper, silver, palladium, or rare elements such as gallium and aluminum. Gold's karat, on the other hand, tells you exactly what percentage of that piece is pure gold versus other metal. Below is an at-a-glance table, followed by a full breakdown of every color and karat.

When referring to types of gold, it is necessary to mention that gold does not refer exclusively to the glittering yellow metal commonly associated with jewelry or wealth. In fact, categorization includes different types of gold as to purity, but it even extends to color and where the gold may be mined. In terms of appearance, this variety of types of gold can impact pricing as well as the appearance and durability of the finished piece.

Colors of Gold

Yellow Gold

Yellow gold is the most commonly used and known kind of this precious metal throughout history. Its inherent beauty, shine, and malleability make it a favorite material worked by different civilizations in their ancient crafting mastery. Up to this date, it is still a popular choice in traditional and timeless jewelry pieces. Based on the karat weight, yellow gold is available in different price ranges where 24k is always the most expensive because of its high percentage content of gold. This type of gold is widely popular in all types of jewelry, ranging from engagement rings to necklaces and bracelets, due to its hypoallergenic nature. It is also the most accessible form of gold in its color, owing to its meaningful availability across cultures and geographies.

White Gold

White gold's exact origin is debated, but it emerged in the 1910s-1920s, with a patent filed as early as 1913, as a more affordable alternative to platinum. Typically plated with rhodium, a robust and shiny metal, it gains more hardness, increased brightness, and some protection to increase its durability. The price of white gold is usually equivalent to yellow gold, though sometimes it adds a small percentage due to additional rhodium plating. If you're deciding between metals for a setting, our comparison of silver vs. white gold breaks down the durability and cost differences in detail. White gold's shiny luster and neutral hue make it an excellent backdrop for diamonds and other gemstones, so it is most commonly found in engagement rings and wedding bands. While a relative latecomer, white gold is now available throughout the jewelry industry.

Rose Gold

Rose gold became especially popular in Russia at the beginning of the 19th century, where it was known as 'Russian gold.' It is distinguished by a high copper content in the alloy, which produces its distinct reddish color — the higher the copper volume, the redder the result. The price matches yellow gold, although it can be slightly cheaper due to the higher amount of more affordable copper. Its vintage appeal and romantic connotation have made rose gold popular across styles ranging from engagement rings to fashionable bracelets and watches. Though not as widely used as yellow or white gold, rose gold is largely embraced in society, particularly for vintage-inspired and contemporary fashion settings.

Green Gold

Green gold has historical significance dating back to ancient Egypt and Greece, where it was known as Electrum. Normally the alloy of silver and gold has a slight greenish tinge, which is enhanced with other metals such as copper and cadmium in its commercial version. The price of green gold is usually on par with yellow gold, but it can sometimes command a premium depending on the alloyed metals and the uniqueness of the piece. Not as widely used as yellow, white, or rose gold, it has found a niche in artisan and specialized jewelry where its color can truly take center stage.

Black Gold

Black gold is actually something of a modern innovation, mainly used in avant-garde jewelry. It is typically made using a layer of black rhodium or ruthenium electroplating, or by darkening the gold's surface through a controlled oxidation process. The special processes and stunning final result often make black gold more expensive compared to traditional gold colors. This bolder, modern take on gold is not yet widespread, but it's growing in popularity among those who embrace this unique style to make their jewelry stand out.

Blue Gold

Blue gold is a truly unique and unconventional form of the precious metal. It's produced by alloying gold with either gallium or indium, both of which can oxidize to produce a bluish tint. Historically, blue gold never achieved the widespread use of more common gold colors, mainly due to the scarcity of gallium and indium and the complexity of alloying them. As a result, blue gold is more expensive and far less commonly found than standard jewelry colors, though its distinct hue makes it a top choice for unusual or custom pieces designed to stand out from the crowd.

Purple Gold

Also known as amethyst gold, purple gold is one of the rarest forms of gold, owing to its composition and the complex nature of working with it. This gold-aluminum alloy is usually rich in gold content but is notably brittle, making it difficult to mold into traditional jewelry. As such, common uses are limited to unique watch components or specialized jewelry pieces. Given its unusual color and the complexity of crafting it into usable forms, purple gold usually carries a higher price tag than more common gold colors.

Gray Gold

Gray gold is an interesting and delicate variation created when gold is alloyed with a small portion of palladium or iron. Though it has a contemporary and unique appeal, gray gold is far rarer in regular jewelry due to the cost of palladium and the alternative appeal of white gold. Its usage is usually seen in specialized or custom pieces, offering a muted color palette for modern designs. Price-wise, gray gold is usually comparable to white gold and only occasionally commands a premium tied to its palladium content.

Each color of gold, with its unique blend of metals and distinct hue, offers a unique appeal and charm. This wide range of colors makes gold one of the most flexible materials in jewelry, easily catering to the preferences and style of almost every person. Whether you're drawn to the traditional allure of yellow gold, the modern shimmer of white and gray gold, or the eccentric appeal of green, blue, or purple gold, there's a type of gold that will be perfect for you.

Yellow Gold	Common	Gold, Copper, Silver
White Gold	Common	Gold, Palladium/Manganese/Nickel, Rhodium plating
Rose Gold	Fairly Common	Gold, Copper
Green Gold	Less Comon	Gold, Silver (additional Copper and Cadmium in commercial versions)
Black Gold	Less Common	Gold, Black Rhodium/Ruthenium or other blackening agents
Blue Gold	Rare	Gold, Gallium or Indium
Purple Gold	Very Rare	Gold, Aluminium
Gray Gold	Less Common	Gold, Palladium or Iron

Gold Karats – What Types of Gold Exist?

Broadly, the unit of measurement that expresses gold's purity defines numerous kinds of gold. Before anyone can understand the worth and excellence of this valued metal, they need to know what a karat means. To better understand this concept, especially where it differs from the "carat" system used for gemstones and pearls, see this informative post on What is a Carat.

24k Gold

• Purity: 24k gold is 100% pure gold. It doesn't contain any additional metals.
• History: The history of 24k gold is rooted in time immemorial. The Egyptians and Greeks many centuries ago admired the purity of 24k gold for its divine quality. From its earliest use, 24k gold has represented value, status, power, luxury, and wealth.
• Usage: Due to its softness, it doesn't find much usage in regular wear jewelry. However, it finds more application in gold bars, coins, or ceremonial artifacts.
• Price: Being the purest form of gold, 24k commands the highest price per gram.
• Popularity: It is not that common in Western jewelry but enjoys popularity in parts of Asia and the Middle East, where traditionally high-purity gold is favored.

22k Gold

• Purity: 22k gold is 22 parts gold and 2 parts other metals like copper or silver, making it 91.67% pure.
• History: 22k gold has been used since ancient and medieval times, commonly applied in coinage and various ornamental decorations.
• Usage: Today, 22k gold is seen extensively in high-class jewelry and ornaments, particularly in countries like India and Saudi Arabia, where gold is frequently bought as investment or status.
• Price: The price for 22k gold per gram is a little lower than 24k, but still comparably high because of its substantial gold content.
• Popularity: 22k gold is not very popular in Western countries, but it is rather famous with the Middle East and South Asia remaining its stronghold.

18k Gold

• Purity: 18k gold has 18 parts gold against 6 parts of other metals — typically copper, silver, or nickel — making it 75% pure.
• History: 18k gold, known for its association with luxury and class, began to gain popularity around the 14th century in different corners of the world.
• Usage: Today, 18k gold is used for just about any type of high-end jewelry imaginable, including engagement rings, necklaces, bracelets, and watches. Balancing durability with a higher ratio of precious metal makes it ideal for pieces meant to be permanent fixtures in any collection.
• Price: 18k gold is cheaper per gram than 24k and 22k due to its lower gold content, but still expensive due to high demand and its high gold content relative to lower karats.
• Popularity: This type of gold is globally popular because it holds an equilibrium between durability, affordability, and high gold content.

14k Gold

• Purity: The purity of 14k gold is 58.3%, since it is 14 parts gold and 10 parts other metals — normally a mixture of copper, silver, and zinc.
• History: The 20th century saw the increasing popularity of 14k gold, particularly in Western countries, primarily due to its affordability and durability.
• Usage: 14k gold is used in a wide range of jewelry, including rings, earrings, necklaces, bracelets, and pendants. It is an all-around type that symbolizes the perfect compromise between durability and cost.
• Price: 14k gold is priced lower than 18k and other higher karats, which makes it the choice for large numbers of customers.
• Popularity: 14k gold is one of the most popular types of gold used for jewelry in the United States and many other Western countries.

10k Gold

• Purity: 10k gold has 10 parts gold to 14 parts of other metals such as copper, silver, nickel, or zinc, making it approximately 41.7% pure.
• History: The use of 10k gold began to trend in the 20th century as an affordable alternative to softer, higher-karat gold jewelry.
• Usage: It is usually used in more affordable forms of jewelry, including rings, bracelets, or pendants.
• Price: Because it is the least pure form of gold that the United States recognizes as gold, 10k gold costs significantly less than higher-karat gold.
• Popularity: Although it is common for jewelry at a lower price range, it still falls behind 14k and 18k in popularity for fine jewelry because of its lower gold content.

Understanding the karats of gold and their characteristics can assist in making a selection of gold for jewelry or for investments. The distinction between the different types depends on factors like preference, affordability, and durability of the product versus the value of the gold.

Karat	Purity	Pros	Cons	Price (Relative)	Popularity
24k	100%	Purest form, highest in value	Soft, not ideal for daily wear	Highest	Less common
22k	91.67%	High gold content, durable	Softer than lower karats	High	Less common
18k	75%	Good balance of purity & durability, high quality and ideal for fine jewelry	More expensive than lower karats	Medium-High	Very popular
14k	58.3%	Very durable, affordable	Lower gold content	Medium	Most popular
10k	41.7%	Most durable, most affordable	Lowest gold content, less bright	Low	Common

Tarnish Resistance of Different Types of Gold

A common question while considering the different types of gold is, "Does gold tarnish?" To this question, the answer would be no; gold doesn't tarnish. However, other metals that form the various alloys combined with gold might oxidize, causing discoloration or tarnish.

It could therefore be said that gold's resistance to tarnishing largely depends on its purity. Higher karat gold, such as 24k, 22k, and 18k, is more resistant to tarnishing due to its higher gold content. Lower-karat gold, such as 14k and 10k, contains larger proportions of other metals, increasing the chance of tarnish, especially under exposure to certain chemicals or atmospheric conditions.

For more insight on when and why gold could tarnish, see this article: Does Gold Tarnish.

What Does "Highest Quality" Gold Mean?

The phrase "highest quality" can sound a little vague when it comes to gold. If we're talking about the purest form of gold, the highest quality would be 24k — 100% pure, but also the softest, meaning it isn't well-suited for everyday jewelry since it scratches and bends easily.

If, instead, "highest quality" means the best option for practical applications like jewelry, then 14k and 18k gold are the top contenders. These karats offer a balance of gold content, durability, and price — containing a higher percentage of gold than 10k while remaining far more durable than 24k gold.

Which Type of Gold is the Most Affordable?

For most countries, including the United States, 14k gold is the most frequently used kind of gold for jewelry. It keeps a good balance between durability and affordability, having a higher proportion of gold than 12k or 10k gold, thus being very popular among those who want to buy rings, bracelets, or necklaces.

What are Rare Types of Gold?

With respect to rare, minor types of gold, one might plausibly conceive of rare gold as material from certain mines or regions. For example, the gold mined during the California Gold Rush or the gold that comes out of the Witwatersrand Basin in South Africa might be considered rare because it was extracted from a specific location at a different time.

Black gold and blue gold are exceedingly rare in terms of both their karats and colors. Black gold is usually formed through electroplating or mixing gold with metals that appear black. Blue gold is an alloy compounded from gold and indium or gallium, produced in relatively small quantities.

Which Color Of Gold Is More Expensive?

The color of gold doesn't usually determine its price — purity and weight do. Though slight differences can be noticed depending on the alloying materials. For example, palladium (used for making white gold) and platinum (used for rhodium plating white gold) are more expensive than copper or silver (used in yellow or rose gold), thus sometimes resulting in a higher price for white gold compared to other types of gold.

However, in most cases, regardless of its color, the most expensive gold is that which has 100% content by weight — 24k gold. Its high price stems both from its 100% content and the premium value added through refining it to such purity.

FAQ

How many types of gold are there?

There are 13 commonly recognized types of gold: 8 distinct colors (yellow, white, rose, green, black, blue, purple, and gray) and 5 karats (24k, 22k, 18k, 14k, and 10k) that measure purity. Color and karat combine independently, so a single piece of jewelry — say, 18k rose gold — reflects both systems at once.

What is the most valuable type of gold?

By purity, 24k gold is the most valuable type since it is 100% pure with no other metals mixed in. By color, gold's price generally doesn't change much, though white gold can cost slightly more due to its palladium or platinum-based rhodium plating.

What is the difference between gold color and gold karat?

Gold color refers to the hue created when pure gold is alloyed with other metals like copper, silver, or palladium, while gold karat measures the percentage of pure gold in that alloy. In short, karat tells you how much gold is present, and color tells you what it was mixed with.

Is rose gold or yellow gold more valuable?

At the same karat weight, rose gold and yellow gold are typically priced very similarly, since both rely on relatively inexpensive alloy metals like copper and silver. Rose gold can occasionally be slightly cheaper because it uses a higher proportion of low-cost copper, but the difference is minor compared to the impact of karat purity on price.
