This specially engineered, exclusively patented metal formulation is a unique blend of tungsten and carbon that creates a material that's one of the hardest materials used in jewelry. In fact, Tungsten Carbide TC.850TM is ten times harder than gold. As one of the most popular choices for men's wedding bands (second only to Gold), Tungsten Carbide is hypoallergenic and known for being the most scratch-resistant metal choice, ensuring your ring will retain its natural color and alluring luster for as long as you own it. The MARCO superior formulation of Tungsten Carbide TC.850TM is our guarantee to you for the life of your ring.
MARCO Tungsten rings are forged together at 1,400 degrees Celsius to form rings that are virtually indestructible. This metal is scratch resistant and always looks permanently polished.
