The marking "18k HGF" on a ring indicates that the piece is made of 18-karat gold, which contains 75% pure gold and 25% other metals for durability. The "HGF" typically stands for "Heavy Gold Filled," meaning that the ring has a significant layer of gold bonded to a base metal, providing a gold-like appearance at a more affordable price. This combination offers the look of solid gold without the full cost, making it a popular choice for jewelry.
