How to Use 24-Karat Gold in Jewelry
Pure gold in jewelry is rare because that pure gold is just too soft to be of practical use. Gold jewelry is more likely to be 14-karat gold or, less commonly, 18-karat gold because those are alloys with other metals mixed in with the gold to give the gold some structural strength.
This doesn't mean you can't use 24-karat gold in jewelry; just that you have to be careful about how and where you use it.
