Hammered black Tungsten Carbide pairs with a Rose Gold interior and offset inlay in the modern, minimalist wedding band. The ring is forged via sintering in an industrial mold, and I polish it with diamond paste.The tungsten carbide that I use is PVD coated, meaning it has gold titanium plating ionized on it in a vacuum. This is THE most durable finish possible. Tungsten Carbide is the most scratch resistant material currently available for a ring. It will never rust nor tarnish, and is entirely waterproof. You can leave your ring in a vat of ferric chloride acid for a year, and it will be entirely fine (although I don't recommend it).
