Vintage 3mm Crystal Gold Stud (Single)

Faceted 3mm crystal catches the light with this delicate little stud. Extra-sharp piercing-style post, prong set in yellow gold with mismatched stamped 925 sterling silver backing 🙃. Cannot confirm grade as was stamped on (now lost) backing; purchased mid-90s with piercing at Piercing Pagoda, so most likely hypoallergenic 14K solid gold (what they use for piercings). Good vintage condition - light surface scratches on post and backing but not visible while wearing.
