{"type":"firestarter.listing","listing":{"id":"lst_D8QKFLIw","product_name":"AAA Curly Hawaiian Koa | Tungsten Carbide Ring 4mm","category":"Ring","description":"Tungsten carbide is the most scratch resistant metal known to man and has the highest melting point of all metals. Tungsten is also hypoallergenic, making it an ideal option for individuals who have allergies to other metals such as gold or nickel.\nThe Carbon Fibre inlay in our tungsten carbide ring is an impressive feature that encircles the band completely and appears almost three-dimensional. Our Thalia name and logo are elegantly laser engraved on the inside of the ring.\nThis ring is the perfect complement to your carbon fibre guitar, and its unmatched durability and beauty will ensure it remains a cherished accessory for years to come.\n ","images":["https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-aaa-curly-hawaiian-koa-tungsten-carbide-ring-4mm-8-24k-gold-28252653125703.jpg?v=1628695320","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-aaa-curly-hawaiian-koa-tungsten-carbide-ring-4mm-5-chrome-28267352916039.jpg?v=1628695320","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-aaa-curly-hawaiian-koa-tungsten-carbide-ring-4mm-28267352948807.jpg?v=1628695320","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-aaa-curly-hawaiian-koa-tungsten-carbide-ring-4mm-28252661645383.jpg?v=1628695320","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-aaa-curly-hawaiian-koa-tungsten-carbide-ring-4mm-28253635903559.jpg?v=1628695320","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-aaa-curly-hawaiian-koa-tungsten-carbide-ring-4mm-28253635280967.jpg?v=1628695320"],"price":40,"currency":"USD","in_stock":true,"inventory_qty":119988,"dynamic_pricing":false,"listed_at":"2026-06-20T18:04:23.924Z","product_rating":null,"product_rating_count":0,"seller_rating":null,"seller_rating_count":0,"units_sold":0,"reviews":{"count":0,"top":[]},"videos":[]},"share_url":"https://firestarter.network/l/lst_D8QKFLIw","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
