I am not always fond of all these digital additions to museums nowadays. But the Diamond Museum in Amsterdam had a computer on which you could take a picture of yourself and crown yourself with one of a few digital crowns or tiaras. Here the result! The tiara or crown used to belong to the Queen of Bavaria. Needless to say it’s mine now!!!
Edited: Mmm, although the museum computer says this one is from the Queen of Bavaria, one of my contacts just says it rather is a replica of the grand tiara worn by Tsarina Alexandra Feodorovna of Russia. And I think he is right.
