Jewelry with any gold content has become of interest since the price of gold has increased. Gold plated jewelry is sometimes difficult to identify, since there are three basic groups of gold jewelry to learn.
Gold jewelry is 9k gold or higher, and may or may not be marked, depending on whether it is made in a studio, or in a large manufacturing plant.
Gold filled jewelry was made in the 1950s and 1960s primarily, and it has more gold content than gold plated jewelry, and is often marked with 1/20 12k gf or similar marks.
Gold plated jewelry has a layer of gold on the surface, and those who test gold with an acid test kit often find that gold plated jewelry will test gold, but is not.
Know the difference in these three categories when purchasing gold jewelry. There is a difference in value.
