Prince William, 39, and Prince Harry, 37, inherited their mother’s amazing jewelry collection, and now their wives have been spotted wearing the sentimental pieces. Most famously, Prince William proposed to Kate with the sapphire and diamond engagement ring that belonged to Princess Diana, and Kate is rarely seen without the piece.

Earlier this month, Katedebuted a pair of dazzling pair of sapphire and diamond earringsthat once belonged to Princess Diana at Trooping the Color.

“This is the first time we’ve seen Kate wear this pair of earrings in public,” Lauren Kiehna, writer ofThe Court Jewellerblog, tells PEOPLE, explaining why it was such a significant reveal.

For the last ten years, Kate has worn a smaller pair of sapphire and diamond earrings that there widely believed to have been fashioned using the very same pair that Kate wore for Thursday’s parade. Because the original pair had not been seen since Diana’s death, the rumor continued to circulate, although Kiehna was always adamant that the earrings were two separate pairs.

Kate andPrince William’s appearance at Royal Ascot comes amid sweltering heat. With temperatures reaching 90 degrees, men were allowed to remove their jackets and ties as the Ascot authorities relaxed the dress code (it’s the first time men have been able to go tie-less!). All spectators were also permitted to bring water and soft drinks into the arena.
