Eugenie and Jack met during a 2010 ski trip in Verbier, Switzerland. At the time, Eugenie said it was “love at first sight”. The Princess was 20 while Jack was 24.

Speaking on BBC’s The One Show about the jewel, Jack added: “Much like Eugenie.”

The stone is therefore not a normal blue sapphire, like the one the Duchess of Cambridge has.

It is pink instead, called a Padparadscha sapphire.

The ring itself features the stone in the centre, surrounded by a halo of sparkling diamonds.

DON’T MISS:

Max from Steven Stone explained how Padparadscha sapphires are “extremely rare stones which many haven’t even heard of”.

He continued: “They are strikingly beautiful with unique shades of pink and orange, often resembling the colours of a sunset.”

Eugenie’s stones are set on a Welsh yellow band, which is the tradition for royal brides.

The diamonds surrounding the main stone is similar to those surrounding Kate Middleton’s ring, as well as Eugenie’s mother’s, Sarah Ferguson.

The expert explained the jewel originated from Sri Lanka and resembles “the area’s peach coloured flowers”.

Max continued: “The term ‘Padparadscha’ is derived from the Sinhalese word ‘padmaraga’ for ‘aquatic lotus blossom’, denoting an extraordinary combination of both pink and orange all rolled into a one of kind gemstone.

“Clarity is an important element for Padparadscha because their light tones easily reveal inclusions – you can see from the traditional cut, this stone is very clear and has a good saturation of colour.”

In terms of the ring’s value, Max estimated it to “be worth around £100,000 to £120,000”.
