What is Gold Purity

Understanding gold purity

Gold in India is more than just a precious metal; it is tied to traditions, festivals, and family celebrations. Whether it is for weddings or savings, purity plays an important role in determining its true value. Purity is usually measured in karats. For example, 24-karat gold is the purest form, while 18-karat gold contains a mix of gold and other metals. Knowing how to check purity of gold helps you understand exactly what you are paying for. It ensures that you get genuine quality, fair pricing, and lasting value. When you are buying jewellery, always check the hallmark and karat markings. This simple step not only protects your investment but also assures you of its authenticity. 

What does gold purity mean?

Gold purity simply refers to how much real gold is present in a piece of jewellery compared to other metals mixed with it. Pure gold is 24-karat, but since it is soft, jewellers often mix it with metals like copper or silver to make it stronger. For example, 22-karat gold has 22 parts pure gold and 2 parts other metals. Understanding gold purity is important because it affects both the value and durability of your jewellery. Wondering how to check purity of gold? Look for the BIS hallmark, which certifies the authenticity of the piece. Checking this ensures you are paying the right price and investing in genuine, long-lasting gold.

Different methods to test gold purity

Wondering if your gold is genuine? There are a few easy and reliable ways to find out:

• Acid test – A small drop of nitric acid is applied to gold. The way it reacts helps reveal the purity level.
• Electronic testers – These modern devices check gold purity by measuring its conductivity, giving quick and accurate results.
• Float test – A simple home method where you place gold in water. Real gold is dense and will sink immediately.
• Hallmarking – In India, the BIS hallmark is the most trusted way to check purity. It confirms that your gold meets certified standards.

These methods, especially hallmarking, ensure you know exactly what you are buying or pledging. So, the next time you want to be sure of your jewellery’s value, try one of these gold purity at home.

How to check gold jewellery purity before buying

Before buying gold jewellery, it’s crucial to verify its purity to ensure you’re getting what you pay for. Look for the BIS hallmark, which certifies that the jewellery meets Indian gold standards. You can also request a gold purity check using a karat meter at the jeweller's. Additionally, it’s advisable to check the gold’s karat rating, with 22k being the most commonly sold in India. Ensure the jeweller provides an authenticity certificate, detailing the gold’s weight and purity. This verification helps protect your investment and ensures the testing of gold jewellery for long-term value and reliability.

What is the difference between 22k and 24k gold purity?

The difference between 22k and 24k gold lies in their purity levels. 24k gold is considered the purest form, containing 99.9% gold with no significant alloys. It's soft, making it unsuitable for crafting intricate jewellery. In contrast, 22k gold contains 91.6% gold, with the remaining portion made up of metals like copper or silver, making it more durable for everyday wear. Due to this added strength, 22k is preferred for gold jewellery. However, 24k is often used in investment forms like coins or bars, offering a higher gold purity but less practicality for jewellery purposes.

How to test the purity of gold using a karat meter

A karat meter is a handy and reliable tool for anyone looking to verify gold purity. Here’s why it is so useful:

• Non-destructive testing – Unlike acid tests, the karat meter does not harm your jewellery, keeping your gold intact and safe.
• Quick results – The device gives instant readings, making it easy for buyers and sellers to make informed decisions on the spot.
• Check all types of gold – From 9 carat gold purity to 24k gold, a karat meter provides reliable results every time.
