Answer
Gold is a suitable metal for jewellery because it is non-reactive, meaning it does not tarnish or corrode easily. Additionally, gold is malleable and ductile, allowing it to be shaped and crafted into various designs without breaking. Its aesthetic appeal and durability make it a preferred choice for jewellery.
