The term 'Granny's Chips' might evoke fond memories of our dear grannies preparing a comforting meal of fried potatoes, but for the Royal Family, it holds a much deeper meaning.There are no sizzling oils or tantalising aromas involved.

Instead, this phrase is the affectionate term Her Majesty used to refer to one of her most treasured possessions - an exquisite diamond brooch that is considered the world's most valuable.The late Queen received these diamonds as a gift from her grandmother, Queen Mary, and only wore the brooch a few times during her 70-year reign.

These incredibly valuable gems hold a significant place in history and a massive value, having been passed down through generations of monarchs, the Mirror reports.Jewellers have estimated that the dazzling accessory composed of two large diamonds, the Cullinan III and the Cullinan IV, which together form a brooch affectionately known by the late Queen as 'Granny's Chips' is worth more than £50 million, making it the most valuable in the world.The precious stones also have an intriguing history, with scientists estimating they were formed over a billion years ago, between 250-400 miles beneath the earth's surface, long before life existed on the planet.

These two diamonds, along with many other jewels in the late Queen's collection, were cut from the unique Cullinan, a larger diamond that weighed an astonishing 3106 carats (or 621.35 grams).
