This piece of Ancient Egyptian jewelry is a rebus pectoral scarab worn by King Tut-ankh-amun from Thebes. It symbolizes the birth of the moon and the sun and was part of the king’s coronation regalia. The glass scarab in the center of the piece was crafted from material taken from a glass field formed when a comet struck North Africa some 28 million years ago. The impact was so powerful, it pulverized the comet’s carbon nucleus into microscopic diamonds which rained down upon a 6000 square kilometer region of the Egyptian and Libyan Sahara Desert.
