The string of appearances led many to speculate that the yellow ring may have been a push present from her husband Prince William, but in fact, the citrine stone dates back over a decade - and is clearly very special to Kate.

While the citrine ring may not have been a gift from her husband, Kate has been lavished with several pieces of jewellery from William.
The most iconic item she owns is undoubtedly her engagement ring, which belonged to Princess Diana and which she received upon her engagement in 2010. The striking band features a 12-carat sapphire surrounded by 14 diamonds and set in 18-carat white gold.
