Went to the last day of the 'Alexander The Great' exhibition from 'The Hermitage' in Russia... this cameo is about 9 inches tall... amazing work... if it's coming to a city near you... and you enjoy your history, don't miss it... was a great presentation of Alexander's life and about 400 fabulous pieces to feast your eyes on...
