Cobalt Rings vs Tungsten Rings

Our clients have a great deal of choices and considerations to make when they decide what is the best ring for them. Factors that people consider are, first and foremost, price and quality. Most Australians want a really good quality product at a solid price.

With the advent of contemporary metals, the landscape has changes regarding a clients needs.  In years past, it was accepted that your ring would scratch and look, well, quite ordinary after only a few months. Thats certainly not the case now. Modern alloys are engineered to provide extreme scratch resistance.

So when people ask the the most durable rings, the answer is always the Black Titanium rings, Cobalt rings or Tungsten Rings. Much has been written about Titanium rings, so we will focus on Tungsten vs Cobalt rings.

Cobalt rings and Tungsten Rings share as many similarities as they do differences. The Key similarities they share is the outstanding durability in day to day wear. Cobalt, much like Black Titanium, is a modern engineering masterpiece. Not only have engineers made Cobalt rings been designed to strongly resemble the “white” finish of platinum, but they have also managed to keep a unique hardness in the product, but still enough ductility and malleability to avoid being too brittle.


Tungsten Rings are extremely hard – harder and more scratch resistant than any other product on the market


Tungsten is more scratch resistant than Cobalt, and is very very difficult to scratch. The trade off with this is that the Tungsten product is more brittle. Cobalt offers a closer balance of scratch resistance with how easy it is to crack. Needless to say, you would have to make a real effort to crack a Tungsten ring, its very unlikely to happen in day to day use. Sometimes you might see retailers claim Tungsten as “unbreakable”. This is a fallacy – its not possible for this to be the case.

As Cobalt is less brittle than Tungsten, it makes it more versatile. Sections can be cut from the ring with less danger of cracking. If you think of an extreme scenario, something very brittle, like glass, its quite difficult to carve intricate designs without cracking – compare this to something less brittle like plastic. This is how Tungsten is to work with. Cobalt doesnt really face this problem, and therefore, there are more range of designs possible with Cobalt rings.

Cobalt rings are less brittle than tungsten, making machining of edges much easier without the risk of cracking

The colour of Tungsten and Cobalt rings is probably the most significant points of difference. Tungsten rings have a somewhat grey hue to them, whereas Cobalt rings, as mentioned above, have a much “whiter” finish, which some people find more appealing.

Cobalt Rings offer a colour similar to Platinum, but harder, and much much cheaper

Cost is the final factor, Cobalt rings can sometimes cost twice as much as Tungsten rings.
