 How to Identify Gold Karat at a Glance

The easiest and most accurate way to identify a gold karat is by checking the hallmark stamp engraved on the piece. This small mark is usually found on the inner side of a ring or the clasp of a necklace, and it indicates the gold’s purity level.

24k → stamped as 999 or 24K

22k → stamped as 916 or 22K

21k → stamped as 875 or 21K

18k → stamped as 750 or 18K

If the stamp is missing or you want to confirm the karat more precisely, there are other methods you can use to test the gold:

1- Acid Test: A drop of testing solution is applied to the surface to observe the reaction and determine the karat.

2- Electronic Gold Tester: Commonly used in jewelry stores, this device provides a quick and accurate reading.

3- Magnet Test: Pure gold is non-magnetic, so this test helps detect the presence of other metals.

How Does Gold Karat Affect Its Price?

The price of gold is directly influenced by its karat rating. The higher the percentage of pure gold in a piece, the more expensive it becomes per gram. For example, the gold price for 24k is the highest, because it contains 99.9% pure gold. It’s followed by 22k, then 21k, and finally 18k, which has the lowest price due to its reduced purity.

To calculate the approximate price of a gold item, you can use the following formula:

Current gold price per gram × (24 ÷ karat) + making charges
