Our rings are made of solid tungsten carbide, one of the hardest materials used in jewelry. It rates about 8.5 to 9 on the Mohs hardness scale, compared to about 2.5 to 3 for gold. Tungsten has a satisfying weight, keeps its polish for years, and our rings are cobalt-free and hypoallergenic. See 10 reasons tungsten is the best wedding band material.

Very rarely. Everyday things like keys, coins and tools won't scratch tungsten the way they scratch gold or silver. Only materials as hard or harder, such as diamonds, can mark it. Learn more in do tungsten rings scratch?

We'll be honest: yes, but only with a hard, direct impact, like a drop onto tile or concrete or a strike from a heavy tool. Tungsten never bends or dents, so a big enough blow can crack it instead. Normal daily wear won't hurt it. Read can a tungsten ring break? for simple ways to protect yours.

Tungsten is much harder and more scratch-resistant than titanium or gold, and it feels heavier and more substantial on your hand. Titanium is lighter, and gold can be resized. Compare them side by side in tungsten vs. titanium wedding bands.

No. Tungsten is too hard to cut and resize, so it's important to order your true size. We carry sizes 2.5 to 19, including half sizes, and every size is the same price. Use our ring size guide, learn how to find your ring size at home, or order a ring sizer for $5.99.

Start with who it's for: men's tungsten wedding bands, women's tungsten rings or matching his and hers sets. Then narrow it down by color (black, gold or rose gold), by shape (classic domed or beveled), or by theme, like cross rings, Thin Blue Line rings and Lord of the Rings. Not sure about width?

These are the same solid tungsten carbide bands you'll see elsewhere for $200 to $400. Here's why ours cost less:

• We only sell online. With no showrooms or salespeople, our overhead is very low.
• We skip the jewelry markup. Jewelry has a massive markup. We'd rather sell more rings at an affordable price than fewer rings at a high one.
• We work directly with the best factories. After many years in business, we've built relationships that get us the best prices, and we pass those savings on to you.
