These Niobium Earrings have been textured and anodized .  The result is a beautiful blue that dances in the light.  The earwires are hypo-allergentic Titanium, also anodized, in a gold hue.
 
Did you know ... Niobium and Titanium are very lightweight metals and very strong.  They are resistant to oxidation.  And, Niobium is more expensive than silver!
