Cobalt vs Tungsten – What’s the Difference

Cobalt vs Tungsten

If you’re shopping for jewellery, you may have heard about cobalt and tungsten. But what is the difference between the two? Both offer the look and feel of precious metals such as gold or platinum, but they differ in strength, durability, affordability, and more. Read on to learn more about cobalt and tungsten to help you decide which is correct.


Cobalt is a silver-white metal used in jewellery since the 17th century. It can be alloyed with other metals or elements to create a strong and durable material that looks similar to white gold or platinum at a fraction of the cost. It is hypoallergenic, won’t irritate people with sensitive skin and is also resistant to tarnish. Cobalt rings are known for their bright shine that will last long without frequent maintenance or polishing.


Tungsten – sometimes referred to as wolfram – is an element found naturally in our environment that was first discovered in 1781 by Swedish chemist Carl Wilhelm Scheele. Tungsten carbide rings are popular among men because they are extremely strong – up to 10 times harder than gold – so they won’t scratch easily or lose shape over time. They also retain their shine very well, meaning less time spent polishing them compared with other metals like silver or gold. However, tungsten rings cannot be resized because of their hardness; therefore, make sure to get your size right before purchasing one!
