Gold has always been a safe and valuable investment, but there is one common issue – purity. Many people buy gold jewellery or coins without knowing if it is original or mixed with cheaper metals. Sometimes, small shops or local sellers cheat customers by selling low-quality or impure gold at a higher price. This creates a lot of trust problems between sellers and buyers.
My idea is to develop a portable gold purity tester, which will be a small and affordable gadget that anyone can use. The device will work with simple sensors or XRF (X-ray fluorescence) technology to check the purity of gold in real time. A person only needs to place the gold item on the device, and it will display the purity percentage (like 18K, 22K, or 24K).My idea is to develop a portable gold purity tester, which will be a small and affordable gadget that anyone can use.

The main beneficiaries of this idea will be normal customers, jewellery shop owners, and gold loan providers who want to confirm the purity of gold before making a deal. This will help people avoid fraud, financial losses, and also build more confidence in the jewellery market.
This problem matters to me because gold is not only jewellery, but also savings for many families. Having a simple and reliable device like this can protect people’s hard-earned money and create more transparency in the gold business......
