Gold ornaments look new even after several years because gold is a very stable metal and does not corrode or tarnish easily. It is also a very soft metal, which means that it does not scratch easily.
The shiny appearance of gold is due to its metallic luster, which is maintained even after many years.
Additionally, gold does not react with most chemicals, so it does not discolor or degrade over time. This means that gold ornaments can retain their original appearance for a long time.
