So we have 10 known brooches! I just discovered this lovely picture of HRH in my archives: do you think it counts as brooch?
Thanks for the information about the Douro brooch. Too bad we don't have a better picture of it. It is diamonds and pearls right? When I was reading your post I started to think how appropriate it is to have a Queen to be patron of a ship named 'Douro Queen'.
About the brooch of emeralds and rubies, to be honest I can't distinguish the colors in it so I'm going to trust you . A close-up would be wonderful.
A sapphire and diamond brooch would be fantastic.
I was joking about the colors, as you noticed. You are so right about the love of TRH for Portugal: a pity many people don't realise that.
