The Queen gave us a bit of a jewelry surprise today, choosing the Diamond Maple Leaf Brooch. It's unusual to see HM wear this brooch at an event not related to Canada, but hey, Canada Day is a week from tomorrow, right? (You can learn all about the brooch's history here.)

Another Canadian featured at the races on Saturday was the Queen's granddaughter-in-law, Autumn Phillips.

She wore golden jewelry to watch the races -- and to present the trophy to the winner of the Windsor Castle Stakes with her husband, Peter Phillips.

The Queen's niece, Lady Sarah Chatto, was also at Ascot on Saturday, wearing her diamond starburst earrings.
