{"type":"firestarter.listing","listing":{"id":"lst_VdIjC27i","product_name":"Round Box-Cut Chain | 14k Solid Gold","category":null,"description":"A study in restraint, this 1mm box chain is designed to disappear into your look while quietly anchoring it. The square links catch light with subtle definition, creating a soft, fluid drape that feels considered and intentional. Worn alone, it offers a barely-there presence. Paired with a pendant or layered with other chains, it becomes a quiet foundation that brings everything together.\nThoughtfully made in solid gold, this chain is meant to be worn often and styled intuitively, adapting easily to whatever you reach for next.\nWe are a small, independent jewelry studio. Each solid gold piece is made to order and crafted specifically for you. Because we source the gold and begin production only after your order is placed, all solid gold designs are final sale.","images":["https://cdn.shopify.com/s/files/1/0524/6107/6679/files/BoxChain_14kSolidGold.jpg?v=1767928412"],"price":1450,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:33.691Z"},"share_url":"https://firestarter.network/l/lst_VdIjC27i","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
