Short answer: tungsten carbide is a compound of tungsten and carbon, bound with nickel or cobalt. It's extremely scratch-resistant, heavier than gold and titanium, and doesn't tarnish. The trade-offs: it can't be resized, and it can crack under extreme pressure instead of bending.
Tungsten carbide rings are an alternative to classic rings, but what exactly is tungsten carbide? And more importantly, is it the right choice for your wedding ring? Here we break down the pros and cons so you can decide.
Made of
Tungsten and carbon, bound with nickel or cobalt
Scratches
Incredibly resistant; the surface withstands just about anything
Weight
Heavier than titanium and 14K gold
Weak points
Can't be resized; can crack under extreme pressure
So what exactly is tungsten carbide?
Also known as wolfram, tungsten was discovered in 1781. This somewhat rare element has incredible properties, including the highest melting point of all metals and the highest tensile strength. It's also incredibly durable.
Because pure tungsten is too difficult to work with, tungsten wedding bands are made from a tungsten carbide compound, with tungsten and carbon atoms in equal numbers. The resulting fine powder is combined with a nickel or cobalt binder, and the compound is then used to make products like blades, cutting tools and wedding bands. Our tungsten rings are cobalt-free: 85% tungsten carbide with a 15% nickel binder.
Tungsten carbide keeps many of pure tungsten's advantages, including high tensile strength and a high melting point. As a result, tungsten wedding bands are incredibly scratch-resistant. Their light gray surface withstands just about anything, and it also suits a wide range of brushed and plated finishes.
Tungsten has moderate electrical and heat conductivity. If you work where electricity or heat could be a safety risk, take your ring off while working; black ceramic rings are a good alternative to black tungsten. Contrary to a common myth, tungsten carbide rings can be removed easily in an emergency with standard jewelry removal tools. Tungsten bands are also heavier than titanium and 14K gold.
Are tungsten carbide rings brittle?
Tungsten carbide is incredibly durable: more so than silver, gold, platinum or titanium, with a highly scratch-resistant surface. But it does have brittle properties. Under enough pressure, a tungsten band will crack and break, unlike gold, which bends on impact.
How brittle is it really? Made from a high-quality tungsten carbide compound, a tungsten ring will break only under extreme pressure. That actually makes tungsten a preferred choice for some people who work with heavy machinery. Read more in Why Do Tungsten Rings Break?
Pros and cons of tungsten carbide rings
Pros
✓ Extremely durable and scratch-resistant
✓ Resists tarnish, patina and corrosion
✓ Ideal for laser engraving
✓ Wide range of styles, finishes and colors
✓ Lower price than gold or platinum
Cons
✗ Can't be resized
✗ Can crack under extreme pressure
✗ Plain gray designs are more limited
✗ Plated colors can scratch over time
Tungsten carbide bands are tougher and longer-lasting than traditional metal rings, and they're well suited to laser engraving, which opens up customization options. Even high-end and designer tungsten rings cost less than gold or platinum; slightly cheaper alternatives include titanium, stainless steel and ceramic wedding bands. See Why Tungsten Is Popular for Affordable Wedding Rings for a price comparison.
Besides resisting scratches, tungsten resists tarnish, patina and corrosion, so non-colored tungsten rings never need re-plating. The main disadvantage is that tungsten rings can't be resized, so keep that in mind if you want a resizable modern ring. See Can Tungsten Rings Be Repaired or Resized?
Silver-gray tungsten is the most scratch-resistant version, but it comes in a somewhat limited range of designs. Men's tungsten rings vary more in style than women's tungsten rings, but designs often stick to simple contemporary styles. Black finishes and gold or rose gold plating add more options.

Choosing the best styles for tungsten wedding bands
Popular men's tungsten styles include diamond-set rings, brushed finishes and flat wedding bands. For women, popular designs include channel-set diamond tungsten rings, thin modern styles and tension-set rings.
For tension-set rings, jewelers offer sapphire, diamond, ruby and moissanite. To withstand the pressure of a tension setting in a tungsten ring, a gemstone should have a hardness of at least 9.0 on the Mohs scale.
For a colored or two-tone ring, inlays are the more durable option. Plating and colored finishes can be more vulnerable to scratches, especially on a ring worn every day.
About black tungsten rings
Most black tungsten rings have black plating over the silver-gray tungsten, so the black finish is more prone to scratching. Modern IP plating (ion plating) is a PVD process that deposits atomic-sized energetic particles onto the ring's surface. The result is a durable finish that outperforms traditional wet plating. IP black tungsten wedding bands are more scratch-resistant than gold or silver rings, but they're more prone to wear than gray tungsten.
The best alternatives to black tungsten rings are black ceramic rings. See also Should You Buy Black Tungsten Rings?
About colored tungsten rings
Colored tungsten rings come in a range of finishes and colors, from simple to complex, and inlays add even more design options. Classic styles include tungsten rings with IP gold or rose gold plating with a brushed finish. Modern colored rings include bright colors like acid green or vibrant blue.
Many retailers use inlays to add color and texture to plain tungsten carbide rings. These more creative rings feature anything from mother of pearl to red opal or green goldstone. Explore more in our Ring Inlay Guide.
Buying tungsten wedding bands: essential tips
✓ Choose a retailer that offers a warranty or a return policy if the rings don't fit perfectly.
✓ Remember that plating isn't scratch-resistant: treat colored tungsten like gold or silver and take it off when cleaning, working out or handling metal objects.
✓ Buy from a retailer that uses high-quality tungsten carbide.
✓ Tungsten can't be resized, so get your finger sized at least twice over a couple of weeks, later in the day. For peace of mind, choose a retailer that accepts returns on non-customized rings.
✓ Watch out for very cheap rings: most high-quality tungsten rings cost over $50.
