This
sterling silver Miraculous Medal has a stainless steel  , lite curb chain, is
1" X 3/4" and is enclosed in an appealing box.  It is heart-shaped, not oval.  

               Mary designated St. Catherine
Laboure as the humble soul through whom she wished the Miraculous Medal to be
disseminated.  She was not disappointed
in her choice.  This Miraculous Medal
pendant would be a great gift for someone who wears one.
