Even though the it may be small, the cleverly curved mirror means you can see your whole face at once!
 
Dating back to 1920, this platinium and sterling silver necklace with paste stones on the chain is both style and substance. Good condition, with a few age related dings to the back of the silver mirror, see pics.
