Rings of Kings: Given to Favourites As a Mark of Honor

Then Pharaoh removed the signet ring from his finger, put it on Joseph’s finger, clothed him in garments of fine linen, and placed a gold chain around his neck.

So the king removed the signet ring from his finger and gave it to Haman son of Hammedatha, the Agagite, the enemy of the Jews.

The king removed the signet ring he had recovered from Haman and presented it to Mordecai. And Esther appointed Mordecai over the estate of Haman.
