On Saturday, Queen Maxima of the Netherlands attended a conference on transgender health care in Amsterdam. For the event, she wore glittering emeralds and diamonds with her bright green coat.

Here's a closer look at the emerald and diamond earrings, which feature pear-shaped emeralds surrounded by a diamond border. You'll note, interestingly, that the earrings are not facing the same direction; one is worn with the point facing up, the other with the point facing down. (The shape of the earrings reminds me a bit of the Duchess of Cambridge's beautiful tanzanite pair.)

We've seen these earrings more often as pendants on a pair of diamond and emerald drop earrings. Above, Maxima wears the earrings at an official dinner for Prince Albert II of Monaco in 2014. Maxima has been wearing these since at least 2006; they are apparently a part of her personal collection.

And here's a good look at the beautiful diamond and emerald butterfly brooch. This is a piece from the Dutch royal vaults; it was a gift from King Willem III to his wife, Queen Emma.
