In this guide, we’ll explore reliable methods for accurately assessing the authenticity and purity of 24-carat gold, helping you make informed decisions and safeguard your investments in this precious metal

To check the purity of 24 carat gold, there are several methods that can be used.

Here are some ways to check the purity of 24 carat gold:

1. Acid Testing: This is the most reliable method to check the purity of gold. You can purchase a gold testing acid kit comprising hydrochloric acid and nitric acid. Rub your piece of jewellery on a black stone similar to the jeweller’s stone and add nitric acid to the mark. If the mark disappears, it is pure gold, but if it stays, it is not pure gold.
2. Hallmark Test: You can use the hallmark test to check gold purity at home without spending anything. Look for a hallmark stamp on the jewellery, which indicates the purity of gold. A hallmark stamp of 24K indicates that the gold is pure. Look for hallmark markings or stamps on the gold item. Pure gold jewelry is often marked as “24K” or “999,” indicating 99.9% purity. These markings are typically accompanied by the manufacturer’s mark or a country-specific hallmark.
3. Magnet Test: Gold is a non-reactive and non-magnetic metal. Therefore, you can use a magnet to check the purity of gold. If the gold is attracted to the magnet, it is not pure gold.
4. Skin Discoloration Test: This is one of the easiest methods of testing gold purity. Real gold won’t leave any stains or spots on your skin. However, if you are allergic to certain metals, this test may not be reliable.
5. X-Ray Fluorescence (XRF) Analysis: A professional can use an XRF analyzer to provide precise information about the composition and purity of the gold item. This method is highly accurate and is often used by jewelers and appraisers.
6. Professional Appraisal: Seek the expertise of a certified appraiser or a reputable jeweler who can evaluate the gold item using various testing methods and provide a reliable assessment of its purity.

It is important to note that 24K gold is too soft to be used for jewellery, so it is usually alloyed with other metals to make it more durable. Therefore, the purity of gold in jewellery is usually less than 24K.
