The Duchess of Cambridge is away on her first solo trip to Denmark, and today was snapped visiting the Copenhagen Infant Mental Health Project at the University of Copenhagen.

For the occasion, she chose jewellery that was chic, sustainable and affordable. Her gorgeous pearl necklace is by British designer Monica Vinader, a favourite of Kate's.

You can buy the chain and the pearl separately, but together they come in at just £120, a reasonable amount for a necklace that should last you a lifetime.

The Duchess has chosen this piece by sustainable British jewellery designer Monica Vinader for her first solo trip. We love the versatility that this particular piece allows for: you can wear the pearl and chain separately or together.

The stunning pendant is made with a cultured freshwater pearl which is rainbow in lustre and features natural irregular silhouettes with varying sizes.

It's also worth nothing that the chain is made from 100% recycled gold vermeil and sterling silver, reducing CO2 emissions by over 60%. Monica Vinader pieces also come with a lifetime repair service, so they're a true investment.

When it came to styling, Kate Middleton paired the necklace with the matching earrings, which was the perfect contrasting touch to her red Zara jacket perfectly.

And proving she is the re-wear queen - eagle-eyed fans will have noticed that this hasn't been the jacket's first outing - she has chosen to re-wear the boucle blazer after wearing it recently, most notably during the football world cup.
