The Queen, accompanied by the Duke of Edinburgh, named the Royal Row Barge GLORIANA; in Greenwich, they granted the borough Royal Borough status, re-opened the CUTTY SARK and visited the National Maritime Museum. Her Majesty opened the exhibition "Royal River: Power, Pageantry and the Thames."
Fun fact: the Queen attended the opening of the National Maritime Museum with her parents and grandmother, Queen Mary, at the age of 11. Only fitting then that she wore one of her mother's brooches, right?
The Queen graced Newbury Racecourse with her presence on her 86th birthday.
Would've gone with a more festive brolly option for my birthday, but whatever. Anyway, she's wearing her single pearl studs again and also a pearl necklace - though with this necklace, it's hard to tell which one.
A collection of pearls as rich as the Queen's obviously has single strands to go along with the two- and three-strand necklaces. As with the other necklaces, it can be difficult to determine if the strands are different or the same over multiple appearances. It is also possible to wear multiple single strands, creating the look of a multi-strand necklace, obviously.
One option is this single strand worn on its own. This is a more informal look for the Queen these days, and is not spotted as often in public.
For most public engagements currently, the Queen wears Queen Mary's Button Earrings. But occasionally she opts for a simple single pearl stud, an option she's used for years. These are usually seen at less formal occasions, or private ones, and were more common in her earlier years. Being such a simple design, it is often impossible to tell if appearances through the years are a single pair or different pairs (it seems highly likely she has more than one pair in her collection), and so they will all be grouped here regardless.
The Queen, Patron, Royal Engineers Association, gave a Reception to mark the Centenary of the Association at Windsor Castle.
In addition to celebrating their centenary, the Royal Engineers used this opportunity to present their patron with a Diamond Jubilee gift: a pair of park benches. You know, I think that might be one of the better (read: usable) Jubilee gifts I've read about.
As she does with many other military groups, The Queen has a brooch version of the badge of the Corps of Royal Engineers (design seen above) to wear when visiting the corps. It appears to be rendered in diamonds and enamel (potentially).
The Queen is also patron of the Royal Engineers' Association, which has a similar badge; this brooch was previously identified on this site as the association badge.
