Why do silver bangles lose their shine after a while?

Silver bangles lose their shine due to a process called tarnishing, which occurs when silver reacts with sulfur and moisture in the air, forming silver sulfide. This reaction can be accelerated by exposure to chemicals, such as those found in perfumes, lotions, or cleaning agents. Additionally, regular wear can contribute to scratches and dullness on the surface. Regular cleaning and proper storage can help maintain their shine.
