What does 18k-H GE mean on a ring?

The marking "18k-H GE" on a ring indicates that the piece is made of 18 karat gold, which contains 75% gold and 25% other metals. The "H" likely signifies a specific manufacturer or brand, while "GE" stands for "gold electroplated," meaning that the item has a thin layer of gold applied to a base metal. This combination suggests the ring has the appearance of gold but is not solid gold throughout.
