The Queen's Sapphire Jubilee

«The Queen has become the first British monarch to reach a sapphire jubilee, after becoming the UK's longest-reigning monarch in 2015, aged 89. A portrait of the Queen by British photographer David Bailey has been reissued for the anniversary. In the photo, the Queen wears sapphire jewellery given to her by King George VI as a wedding gift in 1947. (...) She is Britain's longest reigning monarch, having overtaken her great great grandmother, Victoria, in 2015. Today, after 23,742 days on the throne, it's the start of the first sapphire jubilee in British history. For the Queen, it's a moment for contemplation rather than celebration - as it is also the anniversary of her father's death.» in BBC News
