Black usually isn’t the first color you think of when you think of a wedding ring, but this cobalt band is a modern and elegant choice. The ring is made from cobalt, which is an incredibly durable and lightweight metal, making it a great choice for an everyday piece of jewelry like a wedding ring.

To go along with the strength of cobalt, this ring is pitch black, which makes it a sleek, classy addition to any finger. Plus the black mixed with the flat surface and satin finish gives this ring a modern style.

Comfort Fit

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.

As for strength, cobalt is one of the better options for durability, though not as strong as tungsten. It is impossible to resize but weighs significantly less than other pure metals, like platinum and tungsten. Cobalt rings can be polished to remove scratches and dents.

Cobalt is another affordable metal option, similar in price to titanium and tungsten.
