Tungsten is also hypoallergenic; people with allergies to gold or nickel can wear tungsten jewelry without worry of a reaction.\nTungsten keeps its finish forever and shines beautifully in the light. The Carbon Fibre inlay appears almost 3-D like as it surrounds the ring completely. Our Thalia name and logo are laser engraved on the inside of the ring.  Matches great with your carbon fibre guitar!\nWe offer this ring in two colors: Chrome which is essentially the raw tungsten carbide color and a 24K Gold Plated version.  \nDoes not include black ring gift box with foam and velvet insert shown.  But these are available seperately for $2.99\nGift Box Dimensions:Width: 1.5\" Length: 1.5\" Height: 1.25\"","images":["https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-carbon-fibre-tungsten-carbide-ring-8mm-28249404309575.jpg?v=1628692799","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-carbon-fibre-tungsten-carbide-ring-8mm-13717975859271.jpg?v=1628692799","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-carbon-fibre-tungsten-carbide-ring-8mm-28249375277127.jpg?v=1628692799","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-carbon-fibre-tungsten-carbide-ring-8mm-28249468600391.jpg?v=1628692799","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-carbon-fibre-tungsten-carbide-ring-8mm-8-chrome-28279460462663.jpg?v=1628692799","https://cdn.shopify.com/s/files/1/0797/1743/products/thalia-ring-carbon-fibre-tungsten-carbide-ring-8mm-11-24k-gold-28279464067143.jpg?v=1628692799"],"price":40,"currency":"USD","in_stock":true,"inventory_qty":239976,"dynamic_pricing":false,"listed_at":"2026-06-20T18:04:23.795Z","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_KIY4tYT-","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
