| has gloss | eng: Gold-filled jewelry, also known as "rolled gold" or "rolled gold plate" is composed of a solid layer of gold bonded with heat and pressure to a base metal such as brass. Some high quality gold-filled pieces have the same appearance as 14 karat (58%) gold. In the USA the quality of gold filled is defined by the Federal Trade Commission. If the gold layer is 10 kt fineness the minimum layer of karat gold in an item stamped GF must equal at least 1/10 the weight of the total item. If the gold layer is 12 kt or higher the minimum layer of karat gold in an item stamped GF must equal at least 1/20 the weight of the total item. 1/20 12kt GF is the most common stamp you will find on gold-filled jewelry. 10vkt and 14vkt are also common karatages. Some products are made using sterling silver as the base, although this more expensive version is not common today. "Double clad" gold-filled sheet is produced with 1/2 the thickness of gold on each side. |
