Early hand tooled shell... PORTRAIT cameo brooch....of a sweet young girl.  Realistic details...CRISP.  Naturally domed shell...excellent color contrast and fine polished finish.  Better quality than most!  I love this unusual heavy silver mount.  Dozens tiny flowers with tiny marcasite center.  Gives a scalloped look. On the back there are markings 835 and silver.  835 is European silver. Measures 1 3/4" x 1 1/2".  In excellent condition.
