Titanium metal, unmatched in strength and durability, has an incredible lightweight feel. This metal, traditionally used in the engineering and aerospace industries, is now more frequently being used to craft fine jewelry. Lightweight wedding bands made of titanium are gaining in popularity. Titanium jewelry also has fewer instances of skin allergy when compared to any other metal due to its virtually nickel-free properties. Jewelry made of titanium wears well for active lifestyles. Although virtually indestructible, titanium can be scratched. Polishing with a soft cloth can retain its beautiful finish and keep it looking new.
