Black Cobalt 7mm Wedding Band

Black is an eye-catching color for a wedding ring. That's why this black cobalt band is a great choice. Not only do you enjoy a sleek, elegant look with the flat surface and black color, but the cobalt also makes this ring durable. Cobalt is a strong metal that is great for a variety of lifestyles thanks to its scratch resistance and light weight.

On top of the strength and edge this ring has, we also gave it beveled edges and a satin finish to make it modern from top to bottom.

For a modern, edgy ring, order this 7mm cobalt wedding band.

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

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

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.
