When it comes to choosing a gold wedding ring, one of the most important factors to consider is the karat of gold. A karat is a unit of measurement used to determine the purity of gold. Pure gold is 24 karats, and anything less is mixed with other metals to create an alloy. The higher the karat number, the more pure gold comprises the metal. While 22-karat gold is the purest form of gold used in jewellery, it is not ideal for wedding rings that are intended to be worn daily as it is too soft and may scratch or bend easily. The most popular type of gold for wedding rings in the United States is 14-karat gold, which is highly durable, affordable, and attractive.

What You'll Learn
The purpose of a karat stamp
Gold is often alloyed with other metals to increase its durability, as pure gold is soft and malleable, making it impractical for everyday jewellery like wedding rings. The karat stamp thus helps buyers understand the value of the piece, as gold purity is directly related to its worth.
Different countries have their own requirements and distinctive marks for hallmarking gold jewellery. In the US, for instance, it is required by the National Gold and Silver Marking Act of 1906 that gold jewellery be marked with a karat stamp denoting its purity. In the UK, gold jewellery must be hallmarked in one of the four assay offices located in London, Birmingham, Sheffield, or Edinburgh before it can be sold.
In addition to the karat stamp, gold jewellery may also be stamped with a maker's mark, identifying the designer or manufacturer of the piece. These stamps help buyers identify the type of gold used and the party responsible for confirming its quality.

Popular karat options for wedding rings
When it comes to choosing a karat value for a wedding ring, it is important to understand what karats of gold mean. A karat, not to be confused with a diamond carat, is a unit of measurement used to determine the purity of gold. Pure gold is denoted as 24K, meaning it is 100% pure gold. The higher the karat number, the higher the proportion of pure gold in the metal. Anything other than 24K gold is mixed with other metals such as copper, nickel, and silver to form an alloy.
10-karat gold
10K gold is the least pure and most durable form of gold used in jewellery today. It is also the least expensive option. 10K gold has a subdued, pale yellow colour. It is highly resistant to scratches and wear and tear, making it a good option for those who want a durable ring on a budget.
14-karat gold
14K gold is the most popular type of gold for wedding rings in the United States, accounting for about 90% of all wedding rings. It offers a classic gold appearance without being overly yellow. It is highly durable, affordable, and inherently valuable. It is a good choice for those who want a ring that is suitable for everyday wear without breaking the bank.
18-karat gold
18K gold is a luxurious option for a wedding ring, containing 75% gold. It has a warmer, more yellow tone than 14K gold and is more lustrous. It is also more expensive. While it is durable enough for daily wear, it may not be suitable for ornate rings with intricate styling, as these features can degrade the ring's appearance over time. 18K gold is a good choice for those who prefer the rich yellow colour of pure gold, have metal allergies, or value the inherent value of gold.
22-karat gold
22K gold is the purest form of gold typically used in jewellery, containing 91.67% pure gold. It has a rich, warm tone and is the most lustrous. However, it is generally too soft for everyday wear and is prone to scratching and bending. It is also the most expensive option for gold jewellery. While 22K gold is becoming more popular for jewellery, it is not ideal for wedding rings that are intended to be worn daily.

Pure gold is rarely used for wedding rings
Pure gold, or 24-karat gold, is rarely used for wedding rings. This is because gold in its purest form is soft and malleable, making it impractical for everyday wear. Wedding rings made from 24-karat gold are more prone to scratching, bending, and denting.
The karat system is a unit of measurement that determines the purity of gold. A gold object that is pure gold is 24-karat, while an object that is half gold and half alloying metal is 12-karat. The higher the karat number, the more pure gold comprises the metal. Anything other than 24-karat gold is mixed with other metals such as copper, nickel, and silver to create an alloy, which makes the gold harder and more durable.
The most popular type of gold for wedding rings in the United States is 14-karat gold, which offers a classic gold appearance without being overly yellow. It is also highly durable, affordable, and attractive. 18-karat gold is another option for wedding rings, containing 75% gold. It has a warmer, more yellow tone than 14-karat gold, but its durability is similar.
22-karat gold is the purest form of gold typically used in jewellery, containing 91.67% or 91.7% pure gold. While it has a rich, warm tone, it is generally too soft for everyday wear and is more prone to scratching or bending, making it less ideal for wedding rings.

Gold alloys and their durability
Gold is a popular choice for wedding rings, but pure gold, or 24-karat gold, is rarely used in jewellery. This is because gold is a soft metal and is easily scratched, bent, or damaged. To make gold durable enough for everyday wear, it is mixed with other metals to create gold alloys.
Gold alloys are created by combining gold with other metals such as copper, silver, nickel, zinc, manganese, platinum, palladium, or iron. The type and amount of alloying metal used will change the colour and durability of the gold. For example, white gold is an alloy of gold and at least one white metal, usually nickel, manganese, or palladium. Rose gold gets its reddish tint from the inclusion of copper, and silver is also added to the alloy. Green gold is an alloy of gold, silver, and sometimes copper. The addition of these metals increases the strength of the gold, making it more suitable for everyday wear.
The purity of gold alloys is measured in karats. Pure gold is 24 karats, and each karat represents 1/24th part of pure gold in the alloy. So, 18-karat gold is 75% pure gold, and 14-karat gold is 58.3% pure gold. The higher the karat number, the greater the proportion of pure gold in the alloy. While 22-karat gold is the purest form of gold typically used in jewellery, containing 91.67% pure gold, it is still generally too soft for everyday wear and is more prone to scratching or bending.
The most popular type of gold for wedding rings in the United States is 14-karat gold. It offers a classic gold appearance, is highly durable, and is relatively affordable. 10-karat gold is the least pure and most durable form of gold widely used in jewellery today. However, the higher the karat number, the higher the price tag, so there is a trade-off between durability and cost.

Skin sensitivity and karat choice
When choosing a gold wedding ring, it is important to consider factors such as your career, activity level, aesthetic taste, budget, and skin sensitivity. The karat measurement of gold is a unit of measurement used to determine the purity of gold. Pure gold is denoted as 24K and is rarely used in jewellery, especially rings, as it is very soft and prone to wear and tear. Lower karats of gold are mixed with other metals such as copper, nickel, and silver to create an alloy that is more durable for everyday wear.
If you have sensitive skin, you may want to choose an 18-karat gold ring. 18K gold is 75% pure gold, with the remaining 25% consisting of other metals. The higher purity level of 18K gold reduces the risk of skin irritation or allergic reactions. Additionally, 18K gold has a warmer, more yellow tone compared to lower karats. However, it is more expensive and may be too soft for everyday wear, potentially scratching or bending more easily.
Another option for those with sensitive skin is a rhodium-plated white gold ring. Rhodium adds a hypoallergenic layer to the ring, reducing the risk of skin irritation. However, it is important to note that rhodium plating requires re-plating as it wears off over time. White gold rings generally need to be re-plated every 12 to 18 months.
On the other hand, rose gold is high in copper content, which can cause skin irritation in some individuals. Similarly, 14K gold may exacerbate skin issues for those with allergies to copper, zinc, silver, nickel, or iron. 14K gold is a popular choice for wedding rings due to its durability, affordability, and attractive appearance. It offers a classic gold colour without looking overly yellow.
Ultimately, the choice of karat for your gold wedding ring depends on various factors, including skin sensitivity. It is recommended to consider your specific needs and preferences to make an informed decision.
