Graphite is an electric conductor, consequently, useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.
Peter Carl Faberge’s first egg for the Russian royals is also called the hen egg and was made of gold and white enamel. The inside of the egg had a yolk made of gold within which was a golden hen. The eyes of the hen were made of rubies. The golden hen concealed a miniature crown and at the centre hung a tiny ruby egg.
