Sterling silver is defined as 92.5 percent pure or higher. The remaining 5 to 7-1/2 percent is usually copper. The sterling silver standard has a minimum millesimal fineness of 925.
Sterling Silver cannot rust but it does tarnish. We recommend you to use Wright’s Silver Polish to clean the tarnish in the sterling silver once every 4-6 months.
All our Sterling Silver Picture Frames are made of Sterling Silver 950.
