Gold earring from Mycenae, 16th century BCE.The Greeks started using gold and gems in jewellery in 1,400 BC, although beads shaped as shells and animals were produced widely in earlier times. By 300 BC, the Greeks had mastered making coloured jewellery and using amethysts, pearl and emeralds. Also, the first signs of cameos appeared, with the Greeks creating them from Indian Sardonyx, a striped brown pink and cream agate stone. Greek jewellery was often simpler than in other cultures, with simple designs and workmanship. However, as time progressed the designs grew in complexity different materials were soon utilized.
