Black cobalt may not be the first material you think of for a wedding band, but black rings are rising in popularity along with the durable metal cobalt. Together, these styles make for a modern, edgy, and eye-catching ring. You can feel confident when you choose cobalt, as it’s a strong, lightweight metal. And when paired with the flat surface and step-down edge this ring offers, this ring design is sure to be a hit with anyone who loves modern styles.
We gave this ring a satin finish to make it even more modern and scratch resistant.

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.
