Yes. A tungsten carbide ring can crack, and if you strike one hard enough on a concrete floor or a steel edge, it may break into clean pieces rather than dent. This surprises people who were told tungsten is the toughest ring material available. Both things are true at once, and understanding why will probably make you want the ring more, not less.
Hardness and toughness are different properties
Hardness measures resistance to being scratched or deformed. Toughness measures resistance to cracking under sudden force. Materials engineering trades one against the other constantly. Tungsten carbide is extraordinarily hard, which is why it shrugs off the abrasion that ruins softer metals. The cost of that hardness is brittleness: it does not stretch or bend to absorb a shock, so past a certain threshold it fractures instead.
A gold band does the opposite. It is soft, so it absorbs impact by deforming — it bends, flattens, and scratches, but it rarely breaks.
Why cracking is the safer failure
Consider what happens in an accident. If a soft metal ring is caught and crushed — a car door, a machine, a fall that traps the hand — it deforms around the finger and tightens. Getting it off then means a ring cutter working against swelling tissue, and in serious cases the metal has to be spread apart in stages.
A tungsten ring behaves differently. Because it is brittle, medical staff can crack it off in seconds with a pair of locking pliers, applying pressure until the band fractures and falls away. No sawing, no heat, no working a blade against a swollen finger. Emergency departments know this, and it is one of the reasons tungsten is common among people who work with machinery.
What it takes in practice
This is not a fragile object. Dropping a tungsten ring on a carpeted floor or a wooden table will do nothing at all. Everyday knocks do nothing. What causes a fracture is a sharp, concentrated impact against something equally hard — tile, concrete, a steel workbench edge — usually from height.
The practical habits are simple: take the ring off before heavy lifting, and set it down on a soft surface rather than dropping it onto stone or tile.
The honest summary
You are choosing between a ring that slowly wears out and one that will almost certainly outlive you but could break in a single unlucky moment. For most people the trade is worth it, because the failure mode of tungsten is rare, obvious, and safe — while the failure mode of soft metal is gradual, guaranteed, and occasionally dangerous.
