In ancient Egypt, the opal ring in the hand of Pharaoh has a mysterious legend. When the cat’s eyes are opened, it means that the gods are angry and need to take human life to worship the god so that to make the god calm down and eliminate anger. In addition, when the courtiers entered the Palace, it was said that the Pharaoh decided the official position or life of the courtier with the number of the cat’s eye. Until now, there are still many areas in Egypt to worship the main gods with opals.
