Elizabeth II, Queen of the United Kingdom of Great Britain and Northern Ireland
The Queen marks the 65th anniversary of her accession today. It is the jubilee associated with that most regal stone - Elizabeth II is now the Sapphire Queen.
Elizabeth Alexandra Mary became Queen on February 6th 1952 on the death of her father, George VI. The King died in his sleep at Sandringham and his elder daughter succeeded to the throne at the age of 25.
Elizabeth II's long reign, which began in such sadness six and a half decades ago, has gone on to break records and write itself in the history books. It has had ups and downs but it has been a huge success and every moment shared with her consort, Prince Philip, who marks his own Sapphire anniversary today as well.
Now, as she celebrates a major jubilee that has never been seen before and may not be seen again for many years to come, she is praised as a model of monarchy and held - even by other sovereigns - as an inspiration. Elizabeth II wasn't born to rule but 65 years on, it feels like it could never have been any other way.
Sapphires are said to symbolise wisdom and royalty and have been associated with kings and queens for centuries. Now, in a royal history that stretches back to a different millennium, there is a monarch celebrated by this stone. Another place in history, another chapter to an already fascinating story. Elizabeth II, the Sapphire Queen.
