This 7mm tungsten wedding band features a handsomely woven Celtic knot design permanently laser-etched into the domed surface of the ring. Softened edges and a comfort-fit interior place it among our most comfortable wedding bands! This durable wedding band was cut from a solid piece of Triton TC.850 tungsten carbide, a formula that is scratch resistant, forever polished, and patented for strength. Triton's micro-grain structure insures that each ring has a strength and hardness factor of 8.5 on the Mohs Scale of Hardness as compared to a factor of 10 for a diamond. This classic wedding band combines the highest quality tungsten carbide in the world and a traditional Celtic design to create its unique appeal. Classic style and unbeatable durability, this wedding band complements both casual and formal attire.
