Before choosing your ring, you first need to decide on a metal. In this guide, we'll tell you everything you need to know about wearing Cobalt, so you can decide if it is the best metal for you.


Cobalt is a hard, lustrous, silver-grey metal used most commonly in the manufacture of lithium-ion batteries and magnets. Harder than Titanium and with a slightly heavier feel than Stainless Steel, Cobalt rings will not scratch, shatter or crack easily. Derived from the German word ‘kobold’, a mythological goblin or sprite creature. Historically, Cobalt was believed to be responsible for polluting other mined elements, so miners blamed ‘kobolds’ for this.


Our cobalt is ethically sourced from mines in China before being refined and sent to the UK.


With the addition of 30% Chrome, Cobalt Chrome - as it is sometimes referred to - is a bright white alloy, similar to Platinum or White Gold. 

The same material used to make surgical tools and medical implants due to its high wear-resistance and corrosion resistance, Cobalt in this form will not tarnish. It is ideal for those who like a ring that feels heavier than most and will retain its finish. 

Due to Cobalt’s high tensile strength, specialist diamond-tipped tools are required to cut off in an emergency. However, unlike softer, precious metals, Cobalt won’t bend out-of-round or compress around your finger.



Cobalt rings are available in our four most popular designs; Polished, Matt/Satin/Brushed, Bevelled Edge or Hammered Effect. With a style to suit any taste, which one you choose is completely up to your own personal preference.

For a more traditional ring, with a look similar to White Gold or Platinum, look no further than our Ruskin Green ring. With a highly polished finish inside and out, this style really shows off Cobalt’s bright lustrous white colour. More affordable than traditional precious metals, you won’t notice the difference!

For those who want to stand out from the crowd, our Rivelin Valley ring is a firm favourite in any metal. We think you’ll agree, in Cobalt this hammered effect style is something special.
