{"type":"firestarter.listing","listing":{"id":"lst_dm6JYmfJ","product_name":"Vintage 36 Carat Diamond Buttercup Pendant - Timeless Elegance","category":"pendant","description":"Vintage .36 Carat 4.5 mm Diamond Buttercup Pendant.This natural diamond is 4.5 mm in size, approximately .36 carats and is set in a 14 karat gold buttercup style pendant setting which is 5 mm high. There is one inclusion between two of the prongs, but it is difficult to see without a jeweler's loupe.The rest of it is very clear and I see no color.I went to a jeweler in town on September 14, 2018, and they confirmed that it IS a SL1 (slightly included) D (colorless) diamond. All in all, it's a nice sparkly little diamond.\nChain not included. Shown only for Illustration.","images":["https://cdn.shopify.com/s/files/1/0051/5171/9513/products/il_fullxfull.1676499347_7b32.jpg?v=1754510160","https://cdn.shopify.com/s/files/1/0051/5171/9513/products/il_fullxfull.1629071566_pdiq.jpg?v=1754510160","https://cdn.shopify.com/s/files/1/0051/5171/9513/products/il_fullxfull.1629071504_dbsz.jpg?v=1754510160","https://cdn.shopify.com/s/files/1/0051/5171/9513/products/il_fullxfull.1670199755_d3yp.jpg?v=1754510160","https://cdn.shopify.com/s/files/1/0051/5171/9513/products/il_fullxfull.1387740061_phgt.jpg?v=1754510160"],"price":975,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:07.932Z"},"share_url":"https://firestarter.network/l/lst_dm6JYmfJ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
