The Princess of Wales has worn some stunning pieces of jewellery during her time as a working royal from historic tiaras to heirloom earrings. However, fans of Kate's style will know that she is not afraid of mixing in trend-led pieces with the classics – enter Cartier.

The French jewellery brand was founded in 1847, making it a cornerstone of the luxury jewellery landscape and yet its statement gold watches and daintier necklaces have become some of the trendiest investment pieces. 

It isn't every day that Prince William's wife steps out wearing jewellery from the iconic brand but when she does, it makes a statement. Join HELLO! in touring Kate's Cartier collection and see the jewels in all their glory…
