What does GD925 mean on ring?

The marking "GD925" on a ring typically indicates that the piece is made of gold-plated material with a base metal that is 92.5% pure silver, often referred to as sterling silver. The "GD" suggests that the item has a gold plating, while the "925" signifies the sterling silver content. This combination can mean the ring has a gold layer but is primarily silver underneath. It's important to note that this marking is not an indication of solid gold.
