Princess Eugenie and Jack Brooksbank got engaged back in January 2018, just two months after Prince Harry announced his engagement to Meghan Markle.
On January 22, an announcement came from the Buckingham Palace Twitter account, which shared a heartwarming photograph of the couple, along with the date of the wedding, which would take place later in the year.
However, while Royal fans were excited for the big day, they were also keen to see Princess Eugenie's engagement ring.
Kate Middleton was given the incredible Ceylon Sapphire ring which passed down from Princess Diana, Meghan Markle received a beautiful three-stone diamond ring from Prince Harry - but what would Eugenie's be like?
Interestingly, Princess Eugenie also opted for a sapphire ring, however not a traditional blue sapphire. Her ring features a rare pink Padparadscha sapphire, surrounded by a halo of sparkling diamonds.
Padparadscha sapphires are incredibly rare, much rarer than diamonds.
Our leading diamond expert, Max Stone, said: "These are extremely rare stones which many people haven't even heard of. They are strikingly beautiful with unique shades of pink and orange, often resembling the colours of a sunset."
The stones are set on a Welsh yellow gold band, which is a custom for royal brides, with two stunning tapered diamonds at the shoulders of the yellow gold shank.
It is a similar style to Kate Middleton's cluster style sapphire ring, not to mention another royal who is especially close to the princess.
The ring bares a remarkable resemblance to Eugenie’s mother, Sarah Ferguson’s engagement ring, which features a Burmese ruby, surrounded by diamonds.
Taking a close look at Eugenie's ring, Max Stone reveals all the juicy details.
He said: "The centre stone is an oval cut Padpardscha sapphire, which looks to be around 3 to 4 carats. This is by far one of the rarest gemstones in the world, thanks to its unparalleled salmon hue.
"It is surrounded by 10 brilliant cut diamonds and two pear cut diamonds, which do a remarkable job of emphasising the sapphire, to create an eye-catching finish."
"This sapphire is mainly obtained in Sri Lanka and resembles the area’s peach coloured flowers.
"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."
After seven years of dating, while they were both vacationing in Nicaragua, the wine merchant Jack Brooksbank made a surprise proposal to the Queen’s granddaughter in front of a volcano.
At the time, Brooksbank, whilst on BBC’s The One Show, said the beautiful stone reminds him of his fiancé: “It changes colour when it hits certain lights, much like Eugenie.”
Our engagement ring specialist, Max Stone, added: “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.
"The pink and orange colour has become increasingly popular for engagement rings recently, and it can also be achieved through using morganite as a less expensive alternative...
"However, no expense was spared on Eugenie's ring, which I would estimate to be worth around £100,000 to £120,000”
