The Duchess of Cornwall often wears a classically-designed serpent necklace at gala events. She’s had this one for years and years, and it’s still slithering on.

Queen Alexandra, then Princess of Wales, wears a snake bracelet

With her snake necklace, Camilla’s just following in the footsteps of another Windsor. Queen Alexandra also famously wore a golden snake bracelet wrapped around her wrist.

I’ve seen some describe the pearly circle tiara that once belonged to the Kent ladies as a tiara of coiled snakes. Do you see it?

Surely the most significant royal snake necklace of all is the enormous serpent worn by Sheikha Mozah of Qatar at a Guildhall banquet in 2010. The piece is reportedly by Cartier. Also: THAT RING!

Also fond of reptilian jewelry: the Duchess of Cambridge, who wore crocodile earrings by Patrick Mavros in New York in 2014.

The Duchess of Cornwall doesn’t only wear reptiles: she also has a growing collection of insect jewelry, including a large stick insect brooch.

The Dutch royal collection also includes numerous insect pieces, including this lovely diamond moth.

But the creepiest jewels in the Netherlands, without a doubt, must be the spider brooches worn by Queen Maxima.

And the Bernadottes in Sweden famously own a necklace of scarab beetles, passed down from Margaret of Connaught to Prince Bertil and Princess Lilian, who bequeathed it to Queen Silvia.

But clearly we can’t end a post on buggy royal jewels without a peek at the tiara of diamond and ruby dragonflies worn by Camilla of Bourbon-Two Sicilies. Creepy and elegant!
