This blue coloured tungsten band has a flat top and brushed finish, with bevelled edges. This ring measures 8mm wide and comes in sizes 7 to 13, including half sizes. Tungsten is a very hard, durable metal that is resistant to corrosion, however, the coloured finish can be susceptible to scratching. Due to its high melting point, it cannot be sized, but can be engraved on the inside.
