What does rf 925 mean?

"RF 925" typically refers to a type of silver known as sterling silver, where "925" indicates that the metal is composed of 92.5% pure silver, with the remaining 7.5% usually made up of other metals, often copper. This composition gives sterling silver its strength and durability while maintaining the aesthetic appeal of silver. The "RF" could denote a manufacturer or a specific collection, but without additional context, it's not a standard term associated with silver.
