Vintage Traditional Highland Dirk Brooch(Sold)

This pewter tone brooch is of a Dirk or Dagger set with a glass panel which looks like green marble.  The handle of the dagger is thistle shaped at the top and is very detailed.   The brooch is unsigned but I believe it to be a Miracle creation.  It fastens with a secure roll over type clasp and measures 2.75 inches in length.
