Tungsten wedding bands have become popular due to the metals durability and strength. Rings made with this metal will not scratch or bend making them ideal for any man who works with their hands. Tungsten is around 10 times harder than 18k gold and 4 times as hard as titanium. One problem that some people find with these rings is the weight. Tungsten is denser than other metals and while this allows it to be very strong it also makes it very heavy. If you are not a fan of heavy jewelry then you might have a problem with these bands.
