Unfortunately, tungsten rings can not be resized. Due to the strength and durabilty of tungsten carbide it is near impossible to resize the wedding ring. However mens tungsten rings are far more affordable than traditional precious metal wedding rings. Most owners tend to just replace the band instead of resizing due to the affordability of tungsten carbide. Attempting to resize tungsten wedding bands will lead to breakage. We recommend getting properly sized at a local jewelery store to ensure you get the perfect fit.
