“Eugenie’s historic ring is estimated to be worth around the £100,000 mark, due to its rare padparadscha sapphire.”
There is another royal though, who had a very similar engagement ring, and that is Princess Eugenie’s mother, Sarah Ferguson.

Her ring included a Burmese ruby stone surrounded by diamonds, and it is uncannily similar to her daughter’s in style and colour.

At the time, Buckingham Palace confirmed: “The Duke and Duchess of York are delighted to announce the engagement of Princess Eugenie to Mr Jack Brooksbank.

“Her Royal Highness and Mr Jack Brooksbank became engaged in Nicaragua earlier this month.”
