The details.
Tungsten carbide is one of the hardest materials used in men's rings — this band is built to resist scratches and heavy use that would mark up softer metals. The weight gives it a solid, substantial feel in the hand. This one comes in a 8mm width — Polished finish holds its look well over time. A word for active blokes: tungsten is very hard but doesn't flex, so if you work in situations where ring safety is a concern, consider a silicone backup. Comfort-fit interior makes it easier to get on and off.

Not sure of your size?
Tungsten can't be resized — but in a true emergency it can be safely cut off. Best to nail the fit the first time.

Extremely happy
Hubby wanted something a little different and he absolutely loves it. It looks even better in person, and has a good solid weight to it.
We ordered the wrong size to begin with, but the exchange process was easy, pain free, great communication from customer service and quick turn around.
Highly recommended.
