Found this little brooch in the English midlands - circular brooch set with banded agate - probably a Scottish piece. Set in brass - old style "c" clasp works fine. Late 19th century. These were brought back to England as souvenir pieces from a Scottish holiday - native to the region and considered by many to be a lucky stone. Measures 1 inch across. This one has wonderful Fall colors. Would make a great stocking stuffer - you can still get it by Christmas!
