Sterling silver (925) tarnishes because of a chemical reaction with oxygen or sulfur
particles in the air. If it doesn’t tarnish then it is not sterling silver!

 

How to prevent tarnishing of your jewelry

• Make sure to remove it when you are about to swim or shower.
• Avoid prolonged exposure to sunlight.
• Avoid using perfumes, care and cleaning products while wearing your jewelry. Put your jewelry on last before going out.
• Store it in a cool and dark place in an air-tight container with no other materials to avoid scratches.

How to clean your jewelry

• Firstly, use soap and water.
• If that doesn't work, use baking soda and water and scrub gently with a cloth or a toothbrush. Avoid any stones.
• Polish it with a specifically designed polish cloth.
• If it's heavily tarnished or has stubborn stains, it’s best to take it to a professional jeweler.
