This is an antique Scottish banded agate bar pin dating either to the late Victorian or Edwardian periods.  The agate is in tones of red, orange and white and has very nice translucence.  It is set in silver with a roped edge - the setting is unmarked, but the silver on these old Scottish pins often is unmarked.  It has a C type clasp, which is indicative of the age of the piece.  It measures 2 7/8” in length.  

This is an attractive antique Scottish banded agate bar pin - lovely quality!
