How To Check The Purity Of Gold?

by Zeya By Kundan Writer ZeyaByKundan

Gold is a valuable metal that comes in various levels of purity. 24K represents pure gold, and the Karat system determines gold’s purity. Before buying any pure gold or 24 Karat gold, it is simple to check the purity of the metal. In this blog, we will elaborate on the techniques used for determining the purity of your gold jewellery without affecting its original size and shape.

Why do you need to check the purity of gold?

Before purchasing gold jewellery, it is essential to check the purity of the gold to guarantee the best value for money. Retailers like Kundan Refinery make it simple to purchase pure and genuine gold coins and jewellery online without fuss.

Effective techniques to check the purity of gold

Gold in Indian culture holds a very prestigious pedestal, so it is essential to ensure your jewellery’s purity before making the purchase. Here are some trusted ways to test its purity.

● Check the hallmark sign.

The Hallmark attests to the purity of the gold. This is an easy way to determine the purity of any gold before purchasing any gold jewellery or gold coins. Bureau of Indian Standards (BIS), a reliable government agency, goes through a procedure of labelling every gold piece to confirm the purity of the gold you buy from legitimate shops or online platforms. According to BIS, the hallmarking procedure is carried out to safeguard the public from contamination and to compel gold manufacturers to uphold legal standards of fineness and purity.

● Comparing it with pure gold or 24 Karat gold

Because gold is denser than most metals, this test generally works well for it. The procedure entails comparing the gold jewellery you want to verify with the one whose purity you are certain of. Additionally, you can measure the size with a pair of callipers and a jeweller's scale. A gold coin is considered fake if it differs from pure gold in appearance.

● Acid test

This is one of the most accurate ways to determine the gold's purity, with consistent results. The test must be conducted in a well-ventilated area with the necessary safety precautions. Add a bit of nitric acid on the scratched surface of the jewellery to test its purity. If the surface turns green, it will prove the purity of your gold jewellery. However, If your gold is mixed with sterling, a milky substance will appear to prove its impurity.

● The floating test

Gold is a heavy and dense metal, so the floating test can be another technique to determine the gold's purity at home. When the gold jewellery sinks in a bucket of water, it is composed of pure gold. Even fake gold can sink to the bottom if the alloy contains other dense metals. So, this technique might only be accurate sometimes.

● Vinegar test

In this technique, you only need white vinegar and the gold jewellery you wish to test. Place the gold on a plate and pour vinegar on it with a dropper, if the jewellery changes colour, it is not pure gold. However, if it continues to shine, you have real gold in your hand.

● Magnet test

For this technique to work, you'll need a more potent magnet than the typical household magnet. On a wooden surface, place the gold-plated jewellery you want to test. Gradually get the magnet nearer the gold. If the gold is drawn to the magnet, it is not genuine. Although, if the gold is unaffected by the magnet, it is genuine. Since certain jewellery clasps are made of metals other than gold, the clasp might be drawn to the magnet.

Gold jewellery is the best option if you want something that will last and can be passed down to future generations. Visit Kundan Refinery's official website to explore more options of pure gold or 24 Carat gold jewellery, coins, and bars, and make your perfect purchase from us.
