Who does not like gold and diamonds? There is probably nobody on this earth who would not be impressed by jewellery. When you indulge in jewellery shopped either from a gold shop or an online jewellery store, there will always be a nagging thought at the back of your mind. What if the jewellery is not genuine or whether the diamonds are real or fake.
Adulteration or mixing impurities with gold is nothing new. A leading refinery in India has disclosed that most of the gold it gets for refining does not meet the set purity standards. In Indian culture gifting gold is a gesture of love and respect. But it does not hold any value if the jewellery is not pure.
There are some simple ways to verify the genuineness of jewellery whether you buy it from online jewellery store or from a shop. Some can be done at home with the naked eye and other ways are carried out at laboratories.
- Discoloration: If the piece of jewellery that you are holding shows some areas of discoloration like a different colour, it might be a fake.
- Bite the gold: Pure gold shows the markings of your teeth. The more prominent the marks are, purer is the gold.
- Magnet test: Gold is not magnetic so when you hold a magnet to the jewellery, if it gets attracted, it is fake. But this is not a very fool proof method as many non-magnetic metals are being used in fake jewellery.
- Ceramic test: Take a clear ceramic plate and draw a line across it with the piece of jewellery. A black line left behind indicates fake gold whereas a golden line tells that the piece is real.
- Nitric acid test: This test is a very reliable one. Take the jewellery in a stainless-steel cup and put a drop of the nitric acid on it. Real gold will not react in any way. A reaction which is green, milky or golden indicates that the thing is not genuine.
- BIS mark: Look for a stamp in the shape of a triangle from the Bureau of Indian Standards.
- Year of marking: Most jewellery items have an alphabet code given by the BIS. Such as A tells you that the year is 2000, B states the year as 2001 and so on.
- Identification mark: Usually, most jewellery shop owners have their own authentication mark from the BIS. If the mark is present, you need not be in doubt about the authenticity of the item.
- Hallmarked gold: If you take your gold to BIS, they will take the gold dust and then test it for fineness. The fineness is states in terms of percentage. The purity is graded as 91.6% with 22 karat gold, 75% with 18 karat gold and 14 karat gold indicates 58.5% purity.
- Testing for diamonds: Get your diamond jewellery verified at the Solitaire Gemological Laboratory or International Gemological Institute. If you already have a diamond certificate, you can check the certificate number online. This indicates the genuineness of the set of diamonds in your possession.
Irrespective of whether you make the purchase from an online jewellery store or from a brick and mortar store, these tips would come in handy to help you make the right buying decision.
