{"type":"firestarter.listing","listing":{"id":"lst_3stDEATG","product_name":"Margo Petite Circle Studs | Gold Fill","category":"earrings","description":"The open circle is one of those shapes that works on everyone. There's something about the negative space — the way it frames rather than fills — that makes it feel modern without trying. The Margo Petite Circle Stud is 7mm, small enough to be subtle, defined enough to be noticed.\nThe finish is smooth and polished, catching light in a clean, understated way. No texture, no embellishment. Just a precise circle sitting close to the ear. That simplicity is the whole point.\nAt this size, the Margo is the kind of earring you put on in the morning and forget about — until someone asks where you got them. Wear them alone for a minimal look, or stack them alongside hoops and huggies for something with a little more dimension. They play well with others.\nCrafted in 14k gold fill, these studs are lightweight, durable, and designed for daily wear. Gold fill is a solid layer of real gold bonded to a base metal core, making it a long-lasting and accessible alternative to solid gold. With proper care, these will stay bright for years.\nStandard post and butterfly back.","images":["https://cdn.shopify.com/s/files/1/0524/6107/6679/files/Margo_Petite_Circle_Studs_gold_Fill.png?v=1768694437","https://cdn.shopify.com/s/files/1/0524/6107/6679/products/margo-petite-circle-studs-gold-fill-model.jpg?v=1768694437","https://cdn.shopify.com/s/files/1/0524/6107/6679/products/margo-petite-circle-studs-gold-fill-on-model.jpg?v=1768694437"],"price":48,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:34.140Z"},"share_url":"https://firestarter.network/l/lst_3stDEATG","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
