If you're looking for a wedding band for him that stands out, this is the one to choose. Crafted in tantalum, a darker, very dense metal that is non-reactive and easily worked, this 6. 5mm-wide design glows with a mirror-like finish. Buffed to an ultra-brilliant luster, this comfort-fit wedding band is a bold style. This ring is available in size 10 only. Tantalum rings cannot be resized after purchase.
