Newly minted, but genuine vintage design (see the story below) 1/4" diameter. Made gold plated brass (heavy 7-10 Nickel Free gold). Genuine vintage made in the USA. Well, we had to get on the bandwagon of this trend. The return of the once ubiquitous 70's pop icon: the smiley face. We have the great pleasure of not only joining the trend, but of using the original 70's molds to recreate these stud earrings.
