Pretty antique brass locket.   The locket is 1 ¾ x 1 3/8.  It has a fancy repousse design with a a cameo face on a faux mother of pearl oval.  The left facing “cameo” is black with gold.  The locket is in nice condition and snaps firmly shut.  It is, as found, on a gold filled chain and I just noticed that the single ring at the end of the chain is a replacement as it is silver tone.  Otherwise, very nice.
