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.

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