The World’s Top Five Diamonds




How would you choose the world’s top five diamonds? By cost? Carat? Who owns them?

People occasionally pay insanely high prices for some unique stone, but a diamond’s monetary value depends on social factors that change over time.

That’s why you can’t go by price. Wealthy people certainly pay for excellent quality, but they also buy gems to impress other people or to fulfill some other inner need; or to possess something that was once owned by somebody they admire; or for historic value; or for a multitude of other reasons.

Down a spiraling walkway we went until we reached the point where darkness was broken by bright lights shining on a few showcases. Brilliant jewels behind the bulletproof glass of those cases, among them the Stars of Africa, the Koh-i-Noor Diamond, Prince Edward’s Ruby, and the Stuart and St. Edward sapphires, broke up the light into a thousand different colors and threw it back into our dazzled eyes.

Today the threat of nuclear war has receded and the British Crown Jewels are kept above ground. If you are ever in London, be sure to visit them to see these, some of the most famous gemstones in the world.

The First and Second Stars of Africa were both cut from the 3,106-carat Cullinan Diamond, the largest gem diamond ever found.
