Opal in a stud that feels grown-up, not costume. These are the Sienna Opal Petal Circle Stud Earrings. A petal-shaped circle frames a soft opal center with a gentle color shift depending on the light, warm indoors and almost iridescent outside. The stud format keeps them practical for every day while the opal detail makes them worth a second look. Why you'll love it: Opal center with a soft, shifting color that catches the light in a way that plain metal studs never do. Won't tarnish, won't fade, and won't leave a mark on your skin, so you can wear them every day without a second thought. Small enough to be understated but detailed enough that people ask where you got them, from a casual lunch to a dressed-up evening. Opal styles are popular and these go quickly, so now is a good time to add them to your order.
