Read full description Tungsten carbide is one of the most scratch-resistant metals known to man, highly resistant to scratches, breaks or chips. It is ten times harder than 18k gold, five times harder than steel, and four times harder than titanium. In short, it is the hardest metal on Earth. A tungsten wedding ring offers a unique and affordable alternative to traditional rings, which can cost upwards of several thousands of dollars. The Tungsten Carbide Band personifies a love long as eternity. Tungsten ring cleaning: Your tungsten ring requires no complicated cleaning or maintenance procedures. To make a cleaning solution for tungsten jewelry, simply mix warm water with a few drops of mild soap. It is best to avoid using an ultrasonic jewelry cleaner when cleaning tungsten rings. Keep your tungsten rings away from supersonic cleaner, steam cleaner or harsh chemicals which may cause spotting on the surface of the ring. Tungsten Rings are very durable.
