Black is a subtle choice for a wedding ring, and it makes the ring design modern and fun. And when you add gray edges, it takes the ring to a new level of style and class. This cobalt wedding ring has a two-tone design, making it sleek as well as elegant.
The style isn’t all that’s great about this ring though. The cobalt it’s made from gives the ring a long-lasting durability that keeps it looking shiny and new for longer. And the satin finish is a great way to keep the ring smooth and scratch free.

A comfort-fit design is simple and effective. We add a little extra metal to the inside of the ring to give the interior surface a domed shape. The domed shape is similar to the shape of the outside of a domed wedding band.
The slight dome helps the ring glide over your finger and fit over knuckles. As such, comfort fit is highly recommended for those with bigger knuckles.
With a comfort fit, the size of the ring also fits looser, which means you should verify the correct size before you buy.
Satin is a happy medium between polished and more rugged finishes. It retains a slight shimmer but has a more matte surface than the high polish. The surface will also have slight lines that give it a paintbrush-style texture. This finish is much more contemporary than the high polish finish, making it a great choice for modern rings.
Cobalt has the closest appearance to white gold but with five times more durability. Its white shine can easily be mistaken for other metals like platinum, palladium, or white gold.
