"ER RING" The ring was removed from Elizabeth I’s finger after her death on March 24th 1603. It is mother-of-pearl, the band set with rubies. The ‘E’ has diamonds set over a blue enamel ‘R’. A pearl is also clearly visible. This ring's stunning façade hides a secret – the head is hinged and within it lie two miniature enamel portraits, one of Elizabeth c. 1575 and one of an unnamed woman wearing a costume of Henry VIII’s reign. It is thought that she is Anne Boleyn, Elizabeth's mother.
