If he's looking for a wedding band that's not like all the rest, 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 frozen brush-finished band mesmerizes. Polished to a bright shine, this comfort-fit wedding band is a bold style. This ring is available in size 10 only. Tantalum rings cannot be resized after purchase.
