The details.
If you want a ring that looks the same in ten years as it does today, tungsten carbide is hard to beat. The scratch resistance is exceptional — general daily wear, keys in the pocket, knocks on the workbench. This one comes in a 8mm width — It has a satisfying solid weight without being uncomfortably heavy. The polished surface keeps its shine without replating. Note that tungsten can't be resized, so get your measurement right. Good for blokes who want something tough and permanent.

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