Sinks, faucets, washing machines and dryers can scratch or gouge your jewelry.
Chemicals and abrasive surfaces can also scratch and discolor gemstone and gold. Even diamonds can be chipped when they strike a hard enough surface. Consider placing your jewelry in a safe spot when you are doing household chores. Keep in mind that anywhere near a sink is not a safe spot, because your jewelry could easily fall into the drain or get caught in the garbage disposal.
