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.
EASE OF WEAR AND CARE
With the addition of 30% Chrome, Cobalt Chrome as it is sometimes referred to, becomes 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.
