Titanium cuffs are a really attractive alternative for those who have metal allergies.  This cuff has been hand-textured, flame-painted... and, really pretty.  It is light-weight and, of course, hypo-allergenic.  It measures 6 3/16" from end to end  and is 1-inch wide.  The opening is 1-inch.  
 
A special shout out to Robert Lopez for sharing his flame painting techniques!
