"18kf" refers to 18-karat gold fill, a type of jewelry material that consists of a base metal (usually brass) coated with a layer of gold that is at least 18 karats in purity. This means that the gold content is 75% gold and 25% other metals. Gold fill is more durable than gold-plated items and offers a more affordable option for high-quality gold jewelry. The "f" in "kf" typically stands for "filled," indicating the method of construction.
