TUNGSTEN-BUILT RINGS FOR MEN: Our Thorsten Tungsten rings for men are made from solid and heavy-duty tungsten material. Tungsten is the most scratch-resistant and hardest metal on Earth. That means no metal can scratch tungsten, but non-metals such as diamonds, sapphires, and other crystals that are harder than tungsten can. Its scratch resistance, durability, and lightweight features make tungsten wedding bands for men an excellent choice.
