Along with titanium, tungsten is one of the most popular contemporary choices for men’s rings and jewelry. The tungsten material used for jewelry is actually tungsten carbide, a mixture of the rare metal tungsten and a like number of carbon atoms. Tungsten carbide is incredibly hard, which also makes it extremely scratch-resistant. These weighty rings are very affordable and can be seen in their natural gunmetal grey color as well as in black tungsten and white tungsten, which offers a classic silvery hue that looks more like white gold or platinum. Titanium have that same quality in a lighter weight ring.
