How Many Grams Make 1 Carat of Gold?

People usually buy gold either as an investment or for traditional purposes. However, when buying and selling, people often get confused about terms such as "carat" and "gram." In this blog, we will discuss everything you need to know about the difference between gram and carat, how carat influences gold price, and how you can make a smart buying decision.

Understanding the Difference Between Carat and Gram

First of all, you should understand that carat and gram are two different units of measurement:

• A gram is a unit used to measure weight. When you come across gold rates per gram, it is the price of gold for 1 gram in weight.

• A carat is used to quantify the purity level of gold. It informs you of the ratio of pure gold in an alloy, compared to the ratio of other metals mixed with it, e.g., copper, silver, or zinc.

For example, 24-carat gold means that it is 99.9% pure gold. Meanwhile, 18-carat gold is 75% pure gold and 25% other metals.

So, carats represent the purity of gold, while grams measure its weight. They are two different factors; however, both play an essential role in determining the value of gold coins or jewellery.

How Many Grams Make 1 Carat of Gold?

A carat cannot be converted directly to grams. The term carat is used to express the percentage of gold content in a piece of jewellery, rather than the weight. However, if referring to precious gemstones, like diamonds, 1 carat is equal to 0.2 grams.

If you have 1 gram of 24-carat gold, it indicates that the entire gram is pure gold. However, if you have 1 gram of 18-carat gold, then 0.75 grams consist of pure gold and 0.25 grams consist of other metals.

So, the correct way to understand is:

• Gram = weight

• Carat = purity

In the jewellery industry, the words carat and karat are often used interchangeably. However, they are different. Carat can refer to either gold purity or the weight of precious gems, whereas karat exclusively refers to gold purity.

Why is Gold Alloyed with Other Metals?

Pure gold is too soft and can deform and get scratched very easily. Hence, it becomes difficult to make strong and durable jewellery from pure gold. Therefore, jewellers mostly mix gold with other alloyed metals:

• Usually, copper is added to make gold harder.

• Silver is added for brightness and contrast.

• Zinc increases strength, and Platinum improves durability.

By mixing gold with other metals, it can be made more practical for everyday wear items such as wedding rings, rings, or bangles. That’s why 18-carat gold and 22-carat gold are preferred in jewellery, while 24-carat gold is too delicate.

How Does Carat Affect Gold Prices in India?

The gold price depends on two factors: purity level and weight.

• If you purchase 1 carat of gold jewellery (which contains low gold content), it will be less expensive. This is because it includes many other metals.

• If you purchase 24-carat gold, it will be expensive as it contains nearly 100% pure gold.

Therefore, before making a purchase, it is important to verify the weight per gram as well as the carat (purity). The majority of local jewellers post a table of gold rates per gram on their website or in their store. This is to help buyers and investors compare costs and make well-informed decisions.

Carat System in Gold Explained

Here is an easy way to understand how carat is measured in gold:

The Role of Stamped Marks in Gold Purity

Most jewellers today sell stamped jewellery. During stamping, the carat (purity) of gold is marked on the piece. For example, a ring stamped “18K” indicates it is 18-carat gold.

The stamping system was introduced to help customers verify the purity of their jewellery. Always check for a stamped mark when buying gold from any seller or local jeweller.

Different Uses of Carat in Gold Jewellery

Different gold carats are used in the jewellery industry based on the type of jewellery and the designs:

• 24-carat gold is used in coins and bars, and not in everyday jewellery because it is very soft.

• 22-carat gold is very commonly used in bangles, chains, and heavy jewellery.

• 18-carat gold is primarily used in wedding rings or diamond jewellery because it is durable and can securely hold stones.

• Urban buyers widely use 14-carat gold due to its strength and affordability for intricate designs of gold jewellery.

While buying different gold items, the selection process may vary with the purity level, durability, and your budget.

To Conclude

If you're still wondering how many grams make 1 carat of gold, you should know the difference between the two. A gram measures the weight of gold and is entirely different from a carat. There is no direct correlation, and both serve distinct purposes.

So, the next time you buy any gold jewellery, keep this in mind: gold carats indicate gold purity, and gold grams indicate weight. The real value of gold items depends on both these parameters. They are important to consider when purchasing jewellery, coins, or bars, or mortgaging gold as collateral for a loan.
