Best machined metal men's rings

Top pick: the 8mm gunmetal tungsten band with beveled edges. Tungsten carbide is the hardest metal used for everyday rings, so it shrugs off scratches, and the beveled edges plus comfort-fit interior give a crisp, machined look that still slides on easily. It's the safest choice if you want one ring you never think about again.

Who the others suit:

• Black tungsten dome, comfort-fit — the understated, all-black option if you'd rather the ring disappear on your hand.
• Black tungsten with rose-gold groove — a little contrast for someone who wants a modern accent without stones.
• Hammered tungsten with gold or rose-gold strip — for a warmer, hand-finished feel; hammering hides scuffs well.
• Carbon fiber and wood inlay — the lightest, most textured look, good for someone who dislikes plain metal.
• Titanium with cubic zirconia — the lightest on the finger and the most budget-friendly; titanium scratches more easily than tungsten.
• Hammered band with black sapphires — the dressiest of the group, for someone who wants a ring that reads as jewelry.

One caveat: tungsten is hard but brittle, so it can crack under a hard knock rather than bend — worth knowing if you work with your hands.
