Cobalt is a chemical element (Co) with an atomic number of 27. As a free element, it's naturally a hard, lustrous silver metal.
The pigment cobalt blue was identified in 1802 by the French chemist Louis Jaques Thénard.
While experimenting with cobalt, he discovered mixing cobalt oxide with aluminum oxide created a highly-stable rich blue pigment.
Cobalt blues are gorgeous, vibrant colors.
On the nails, cobalt blue is a fantastic summer color. It’s reminiscent of deep, clear ocean waters and makes a stunning compliment to any look.
Below are swatches of four of the best cobalt blue nail polishes we’ve found so far, all in 2 coats.

It’s the namesake of the 2023 push play summer collection and a creamy cobalt blue that’s very easy to apply.

China Glaze Crushin’ on Blue
Thank you China Glaze for sending this shade!
Shown in 2 coats and in China Glazes NEW formula launched Spring 2025, This bright, sapphire blue is packed with pigment and Hexanal, a keratin strengthener.
It has a chip-resistant finish for a longer weartime and a new wide, round brush, which might be the best part - it gives you a smoother application in fewer strokes.
