The short answer is that the entire collection is priceless—literally. The British Crown Jewels are not insured, because no one can reasonably put a dollar figure on objects that hold such immense historical and cultural significance. That said, experts have tried, and the estimate for the core collection housed in the Tower of London hovers somewhere around £3 billion to £5 billion (that’s about $4 to $6.5 billion USD).
But let’s break that down into something you can actually visualize. The St. Edward’s Crown, used for the actual moment of coronation, is made of solid gold and weighs nearly five pounds—imagine wearing a small bowling ball on your head for a few hours. It’s set with 444 stones, including amethysts, garnets, and topazes, and its gold alone is valued at over £1 million.
The Real Heavy Hitters: Diamonds and Sapphires
The Imperial State Crown is the one you see Queen Elizabeth II wearing in official portraits and during the State Opening of Parliament. It contains 2,868 diamonds, 17 sapphires, 11 emeralds, and 269 pearls, including the legendary Cullinan II diamond (the second-largest stone cut from the Cullinan diamond, weighing in at 317.4 carats). Diamond experts estimate that just the gems in this crown could be worth over £3 billion on their own.
Then there’s the Sovereign’s Sceptre with Cross, which holds the Cullinan I diamond—a flawless 530.2-carat monster. To put that in perspective, a single carat of top-quality diamond can cost $20,000, so you’re looking at a stone worth roughly $10.6 billion if it were ever to be sold. Spoiler: it won’t be.
