In Norse Mythology Baldur, son of Odin, was the god of Light and Joy. This black faceted wedding band exemplifies the inverse of Baldur's light. We grind the faceting on this Tungsten Carbide ring on a massive 16" disc sander. As each wearer is unique, so is each ring. Tungsten Carbide is the paragon of modern metal working. It's at twice as hard as steel, and heavier than gold. Our Tungsten Carbide is PVD IP plated in a vacuum, and will always look exactly like the day that you received it.
