Here is a beautiful and very sparkly pin of a butterfly, in an art deco style with straight angles.  It is in perfect condition, might be new.  I am not sure of the history of this pin.  The center stone seems to have the lightest blue cast at times. It measures 2 1/4" tall and 2 1/4" wide.   Shipping is free, and it includes a padded envelope for first class mail and tracking.
