Queen's 'rare' engagement ring sparkles with 'beautiful fire' – 'Priceless!'

“No longer cut to these proportions; these rare old brilliant-cut diamonds sparkle with their own beautiful fire and brilliance.

“More of these diamonds were also made into a matching diamond line bracelet which was a wedding day gift from Prince Philip to his new wife to complete the jewellery collection.”

In terms of value, Ms Dimmick estimated a similar ring would be worth a six-figure sum, but the provenance of the Queen’s ring makes it all the more special.

She explained: “Capturing the post-World War 2 austere mood of the time, this style and proportion in 1947 was actually deemed to be fairly modest for a young Princess.
