Cobalt

Cobalt is extremely scratch, chip and corrosion-resistent. Its lower density and natural malleability allow for strong, dynamic design. Cobalt's traits make it scratch-resistent and stronger than most other precious metals. Cobalt is also a good choice for those with sensitive skin or those who suffer from allergies, as cobalt is hypoallergenic.

Make a fashion statement with cobalt:

• Cobalt literally works with almost every other color: Black, navy, camel, grey, white, orange, green and all other shades of blue.
