When a young Prince William and then-Kate Middleton met at St Andrews, it was only a matter of time before they made their relationship official. Though the couple waited nine years before they got engaged following a brief split in 2007, the Prince of Wales gifted his wife-to-be a premarital ring that proved he was smitten with his university flatmate long before they tied the knot.

Now a member of the royal family and the future Queen Consort, Princess Kate's jewellery collection is seriously impressive.
From diamond-encrusted tiaras to glittering royal heirlooms and even some of Queen Elizabeth's former jewels, the royal's personal collection is rather impressive - though nothing is as heartwarming as her first ring from Prince William.

Before they were married, it's believed that Prince William gifted Kate a rose gold ring encrusted with their birthstones. The love token featured both pearls - representing William's birthstone - and garnets, representing Kate's.
Eddie LeVian, CEO of jewellers LeVian told The Express: "This beautiful, delicate ring is understated in style, but the very personal message hidden within it from a future King makes it an enormously romantic royal jewel."

The Princess of Wales wore the sentimental ring to her graduation in 2005, proving her affection for William and as a sign of her commitment to her future as a royal.
LeVian added that the stones set in the ring symbolise love, purity and protection.

It wasn't just jewellery that romanced a young Kate at university. "[William] did cook for me quite a bit at university, and he would always come with a bit of angst and a bit of anger if something had gone wrong and I would have to wander in and save something that was going," Kate previously told ABC news.
"I would say I'm getting better at cooking. Kate would say I'm getting a lot worse," William replied, before Kate admitted: "I don't give him enough chance to practice!"
