Princess Eugenie’s engagement ring is the spitting image of Sarah Ferguson’s

Princess Eugenie is engaged to her fiancé Jack Brooksbank.

Sarah Ferguson, Duchess of York, 58, took to social media to celebrate the engagement of her daughter, Princess Eugenie, 27, to Jack Brooksbank, 31.

Sweet snapshots of the Princess with her wine merchant fiancé show off her dazzling ring.

In royal style it has a coloured centre stone flanked by diamonds, and is very similar to her mother’s.

HRH Princess Eugenie of York was given a rare “lotus blossom” sapphire, which an expert has valued at around £7,000 – modest for a royal ring.

The light pink ring is an oval cut, flanked by diamonds and set on a gold band.

A padparadscha sapphire like Eugenie’s is characterised by a colour that is a mixture of red and yellow, creating a pink tone.

Sophie Lomax, head of design at 77diamonds.com, estimated the price of Eugenie’s rock at £7,000, according to the MailOnline.

She said: “Princess Eugenie’s ring features an oval cut padparadscha sapphire encircled with a cluster of pear-shaped diamonds. 

“Padparadscha sapphires are typically found in Sri Lanka and are one of the rarest colour of sapphire, being a beautiful and unique mix of pink and orange.

“The ring style that Jack has chosen Eugenie is reminiscent of the engagement ring Sarah Ferguson was given by Eugenie’s father, Prince Andrew.”

Sarah Ferguson’s ring, on the other hand, is said to have cost £25,000 when it was purchased.

Sarah posted a number of sentimental images of her daughter and husband-to-be.

Another photo, of Eugenie and Brooksbank in profile staring into the distance, said: “A total embrace of goodness and joy. 

We love Jack and I am so excited to have a son, a brother and a best friend.

Eugenie is one of the finest people I know and so together it will be pure harmony.”
