Huge cameo of Aurora

This is a HUGE MUSEUM QUALITY CARVED CAMEO OF AURORA OF THE DAWN.I have only seen one other this involved. You have Helius and cherubs,horses,4 winds,Eos,maidens,etc.etc.The size is 2 1/4 by 2 7/8 HUGE.The frame looks to be copper and Pinchbeck..Has the c and t pin and a tiny loop top center for safety chain.Much nicer in person.From around 1840. There are a few natural lines only seen when held to light.The cameo is mint.
