Does 925 Sterling Silver Tarnish & Ways to Prevent It

Tarnish is chemistry, not a defect. Here is what causes it and the storage, coating and plating choices that slow it down.

Tarnish forms when silver reacts with sulfur compounds in air, forming dark silver sulfide on the surface. Humidity and pollution accelerate it.

Manufacturers fight tarnish with palladium barrier layers, anti-tarnish e-coating, and sealed packaging with anti-tarnish strips.

For consumers: airtight storage, a soft polishing cloth, and wearing jewelry often (yes, really — skin oils slow tarnish) are the simplest defenses.
