Sparkling Royal Jewels From Around the World

For the second week in a row, a European royal family rolled out the red carpet and piled on the tiaras to host the Emperor and Empress of Japan. Here’s a look at all of the tiaras and jewels worn for tonight’s Japanese state banquet in Belgium.

I had a feeling the Emperor and Empress of Japan’s tour of Europe this month was going to bring out some major jewelry, and I’m happy to report that I was right: we were treated to seven (!) imperial and royal tiaras at tonight’s state banquet in Amsterdam, including a tiara debut!

The Grimaldis were out in Monaco this weekend for the annual Rose Ball, with jewels sparkling on four Monegasque ladies—and an imperial guest from Japan.

Last week, the Japanese imperial family gathered in Tokyo to celebrate the Emperor’s birthday, with plenty of classic brooches, earrings, and pearls worn for the occasion.

I previously covered the gorgeous tiaras worn by the Japanese imperial family to welcome the new year, but the empresses and princesses also wore some lovely brooches to greet the public at the start of 2026. Here’s a closer look at the jewels worn for the traditional balcony appearances on the second day of the year.
