"The round diamond shoulders two tapered baguettes, which gives the ring a vintage feel and Art Deco-inspired look. For added sparkle, the ring also features small pavé diamonds halfway around the band.
"From the images, it's clear the diamonds are VVS grade, which means they have miniscule inclusions that are difficult even for trained eyes to see under 10x magnification. The diamonds look flawless.

"With this in mind, I would estimate the value of this ring to be around £130,000 to £140,000. Thanks to its royal legacy, this will no doubt increase in years to come."
It is not dissimilar to the Duchess of Sussex's engagement ring from Prince Harry, which follows a trilogy design. The central diamond is also sourced from Botswana, like Beatrice's, while it is flanked on either side by two smaller jewels from Princess Diana's personal collection.

The 5-carat gem was previously valued at £134,500, however, Max estimated the ring is worth around £97,000.
Meanwhile, Her Majesty's art deco ring from the late Duke of Edinburgh is also flanked by diamond panels created from his mother Princess Alice of Battenburg's tiara. It is reportedly the most valuable of them all, worth £207,000 according to Max.
