What is Cobalt?

Cobalt is an alternative metal that has gained popularity in contemporary jewelry design, from necklaces and bracelets to wedding rings. It is extremely durable, and has a natural white luster, comparable to white gold and platinum, which makes it a popular choice for men’s and women’s jewelry.

Cobalt vs. Stainless Steel

Cobalt is often compared to another common metal, stainless steel. Stainless steel is used in everything from cookware to wearables like chain necklaces and watches. However, cobalt jewelry is much harder to scratch than stainless steel and requires less care over time. Cobalt’s strength and durability make it a great choice for people who want beautiful jewelry without all the upkeep. So, if you’re looking for a metal with lasting strength, you can’t get much better than cobalt.

Cobalt History

Cobalt is a contemporary metal. It was first discovered and named in 1739 by chemist Swedish George Brandt. Cobalt is generally an industrial metal, used in everything from surgical tools to jet plane engines, but there is more to this metal than just strength.

Cobalt also has a connection with art world. Pigments in artists’ paints are usually crafted from minerals and ores. As new metals are discovered, they can be used to create distinct color shades. This was the case for cobalt. After cobalt’s discovery, chemist Louis Jacques-Thenard found a way to create a new pigment with the metal, called cobalt blue. The color became instantly popular with artists at the time. A prime example is Vincent Van Gogh, who used cobalt blue heavily in his works. You can see cobalt blue all over Van Gogh’s most iconic painting "The Starry Night."
