On average, how old is a diamond?
Diamonds are formed over a period of millions of years deep within earth's crust – about 150km (90 miles) deep. Within time, they are pushed to the surface by volcanoes. Most diamonds are found in volcanic rock, called Kimberlite, or in the sea after having been carried away by rivers when they were pushed to the surface.
A diamond is 58 times harder than corundum, the next hardest mineral on earth, out of which rubies and sapphires are formed. Only in the 15th century, it was discovered that the only way to cut diamonds was with other diamonds.
What is the largest diamond in the world?
The world’s largest diamond known to men was the Cullinan, which was found in South Africa in 1905. Uncut, it weighed 3,106.75 carats. The Cullinan was cut into the Great Star of Africa (530.2 carats), the Lesser Star of Africa (317.40 carats), and an additional 104 other diamonds of nearly flawless colour and clarity. Today, these diamonds form part of the British crown jewels.
The Cullinan was three times the size of the next largest diamond, the Excelsior, which was also found in South Africa. The world’s largest documented polished diamond, which was unearthed in 1986 in South Africa, is called the The Golden Jubilee. It was cut down from a 700 carat rough diamond and weighs 545 carats. The diamond took almost 3 years to cut, just like the Centenary Diamond, which also forms a part of the British crown jewels. This last one weighs 273.85 carats and is considered the world’s largest flawless diamond.
The biggest diamond in the entire universe is thought to be Lucy, a crystallized white dwarf star. It is actually a burned out star from diamonds. It was discovered about 50 light-years away from Earth in the region of the sky we refer to as the constellation Centaurus. Its weight is 10 billion trillion carat. Named after the Beatles song, Lucy in the Sky with Diamonds, the star is technically known as BPM 37093.
