If you’re even a small fan of the British royal family, you’ve likely seen Princess Diana’s unforgettable sapphire engagement ring, which her son Prince William gave to Kate Middleton when he proposed to her. Though the large blue stone and surrounding circle of diamonds is beloved by people all over the world, it was recently revealed that the royal family has not been fond of it from the very beginning for a surprising reason.

The royal family’s dislike of the ring has nothing to do with it’s design. Instead, they dislike it because it was not crafted specially for the late Princess of Wales. The piece of jewelry came straight out of crown jeweller Garrard’s catalogue, meaning that anyone with CAD$46,000 could have bought the jewel at the time.

Though the ring was accessible for anyone, it had a royal inspiration. The ring was inspired by a sapphire and diamond brooch given to Queen Victoria by Prince Albert back in 1840.

Diana loved the ring so much that she continued to wear it even after her divorce from Prince Charles. She eventually stopped wearing it in favor of an aquamarine ring, which Prince Harry gave to Meghan Markle to wear for their wedding reception.

William gave Kate the sapphire engagement ring when he proposed to her while the two were on vacation in Kenya.

“I’d been carrying it around in my rucksack for about three weeks before [proposing] and I literally would not let it go. Everywhere I went, I was keeping a hold of it because I knew, this thing, if it disappeared, I’d be in a lot of trouble,” William said in an interview. “It’s my mother’s engagement ring … Obviously, she’s not around to share in the fun and excitement of all of it. This is my way of keeping [Princess Diana] sort of close to it all.”
