OOAK Handmade Sterling Silver and Gold Pyramid Stud Earrings

Gorgeous handmade pyramid stud earrings made of sterling silver with a genuine yellow gold layer on the front (not plated, you can see the thin layer of gold). I can’t remember what this technique is called! Completely handmade a one of a kind, unfortunately don’t remember the artist. Hardly worn. Approximately 0.25” but sides aren’t exactly even
