What does 14kmg mean on a gold chain?

The term "14kmg" on a gold chain typically indicates that the piece is made of 14 karat gold with a gold plating or coating. The "mg" stands for "milligram," suggesting that the gold layer is measured in milligrams, indicating a thin plating over a base metal. This means that while the chain has the appearance of gold, it may not have the same value or durability as solid gold.
