I love these! Chock-full of natural gold nuggets and made in solid 14k yellow gold, it dates from the 1950's. The gold nuggets are likely from Alaska. Generally speaking, the nuggets are 18k or higher.
Marked 14k on the nice size bail, it measures 1 1/8" tall by 5/8" at the widest point. Very well made, nicely detailed rope frame, glass front and glass back. The locket can be opened with a tiny flathead screwdriver.
In excellent condition, overall approximate weight is 2.1 gram.
