Queen's nickname for diamond brooch worth over £50 million and who owns it now

ok.co.uk:

With their dazzling crowns, breathtaking engagement rings and stunning tiaras, the royals are known for having a jewellery collection that most of us could only ever dream of.

And prior to her tragic passing earlier this month, the late Queen Elizabeth II was the owner of an incredible diamond brooch which was widely known to be the most valuable of its type in the world.

Made up of two giant diamonds - called the Cullinan III and the Cullinan IV - the monarch only wore the accessory a handful of times during her record-breaking reign, making each time a sight to remember when she did.

According to jewellery experts, the brooch is likely to be worth more than £50 million given that the Culian III weighs 94.4 carats and the Cullivan IV weighs 63.6 carats.
