Speaking of material, let's talk about what men's wedding bands are often made from. This may be the most important factor when it comes to wedding band shopping.
Of course, you have classic precious metals like a sterling silver and gold. And within gold wedding bands, you have rose gold, white gold, and yellow gold. With these materials, you'll want to research which one fits your lifestyle the best in terms of comfort, fit, durability, hypoallergenic, etc.
Platinum, palladium, stainless steel, and titanium are great traditional metals. Alternative metals like tungsten, Damascus steel, and ceramic are gaining popularity as well.
Titanium rings and tungsten wedding bands are very durable, but they're also unable to be resized. In contrast, softer materials like gold may get a few scratches but can be resized if needed.
Do some research on the pros and cons of common materials to see which ones fit your criteria. You'll also, of course, want to consider the color of the material for your wedding band.
