With Ruby and Emerald, that philosophy takes on richer color and greater visual depth—tones that read classic at a glance, but reveal complexity as they move through light.\n\n\n\n Eclipse: Ruby brings a deep crimson character—confident, warm, and unmistakably expressive.\n\n\n Eclipse: Emerald offers a saturated green with a refined edge—cool, architectural, and quietly commanding.\n\n\nBoth are made to stand out without shouting—pens that look composed on a desk, and unforgettable in hand.\n\nNahvalur Eclipse Emerald Fountain Pen Specifications:\n\nPen Material: Aluminum\nTrim: Rose Gold\nNib: Stainless steel made by Nahvalur\nFilling System: Converter\nPen length, closed: 5.91 in. / 150mm\nPen length, open: 5.83 in. / 148mm\nPen Diameter, barrel: 0.55 in. / 13.91 mm\nPen weight (without ink): 1.2 oz. / 34g\nGift boxed with user guide and 1-year warranty\n\n","images":["https://cdn.shopify.com/s/files/1/0575/7177/files/Nahvalur-Eclipse-Emerald-Fountain-Pen.jpg?v=1775662688","https://cdn.shopify.com/s/files/1/0575/7177/files/Nahvalur-Eclipse-Emerald-Fountain-Pen-2.jpg?v=1775662689","https://cdn.shopify.com/s/files/1/0575/7177/files/Nahvalur-Eclipse-Emerald-Fountain-Pen-3.jpg?v=1775662691","https://cdn.shopify.com/s/files/1/0575/7177/files/Nahvalur-Eclipse-Emerald-Fountain-Pen-4.jpg?v=1775662693"],"price":99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:58.982Z"},"share_url":"https://firestarter.network/l/lst_Oyr4xVBO","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
