Cobalt, an extremely durable alloy, is four times harder than platinum despite being less dense. Cobalt jewelry is very scratch, chip, and corrosion-resistant because to its natural hardness. Its decreased density and natural malleability enable powerful, dynamic shapes that are less in weight. Because cobalt is hypoallergenic, it is an excellent choice for persons with sensitive skin or who lead an active lifestyle. Shiv Shambu has two finishes: a deep ebony hue and a natural, glossy white that will keep a lifelong shine. Cobalt has a similar hue to platinum but does not require rhodium plating and does not tarnish.
