My parents invested in a lot of gold jewellery but now that they want to sell it for cash, it's turning out to be a big loss for them. They buyers are offering a price much lower than what they invested. Apparently, jewellery entails making charges while buying. But only the weight of gold will get you money when you want to sell.
If you want to invest in gold, buy solid gold. Not jewellery. You'll only end up in loss like us.
