While Kate has borrowed many pieces from the Queen’s collection, her own one includes an impressive ruby ring that she has worn over the years.

It is also thought to have a huge price tag.

Speaking to Express.co.uk, Roseanna Croft, the founder of Roseanna Croft Jewellery, explained: “The Duchess of Cambridge’s ruby ring I estimate to be worth in the region of £35,000 and is a stunning piece of timeless yet ‘on trend’ jewellery – a step away from the traditional jewels worn by the Royal Family.

“The setting is elegant and really helps the stone to stand proud in the ring with a simple diamond set band accentuating the ruby even more.”
