Palladium, one of the rarest metals in the world, is a member of the Platinum Group Metals. These metals are also referred to as "Noble Metals" due to their superior ability to withstand corrosion and oxidation.

Tungsten Carbide

Unique in appeal and strong by design, tungsten carbide is a forged metal with qualities that will last a lifetime. Tungsten carbide jewelry is created from an alloy of 80% elemental Tungsten and 20% Carbon alloyed with other metals.


Made from a highly durable alloy, cobalt is four times harder than platinum while at the same time, less dense. Because of its natural hardness, cobalt jewelry is extremely scratch, chip and corrosion-resistant. Its lower density and natural malleability allow for strong, dynamic designs with less weight. Cobalt is also hypoallergenic, making it an ideal choice for those with sensitive skin or an active lifestyle.
