Good question! Tantalum is a super rare, hard, blue-grey metal which is highly corrosion resistant. Found most-commonly in electrical capacitors for computers, mobile phones and games consoles, there's predicted to be less than 50 years of Tantalum resources left in the world. The name is derived from the Greek mythological villain, Tantalus, due to its ability to resist liquids.
EASE OF WEAR AND CARE
Tantalum is extremely resistant to rust, corrosion or tarnishing, which makes it a great choice for those with active lifestyles. However, it is highly conductive of heat and electricity so extra care should be taken in those environments.
