Ancient Romans and Greeks considered diamonds to be the tears wept by the Gods, they also thought they may be chips from falling stars. Maybe the earliest association of diamonds and true love is the Romans beliefs of Cupid’s arrow heads were encrusted with diamonds.


Diamonds are so old some may even be as old as 3 billion years.


Diamonds are formed at high temperatures and pressures about 100 miles below ground in the Earth’s Mantle. They are eventually pushed up towards the surface by volcanic eruptions.


Diamond derives from the Greek word “adamas”. Adamas means invincible, and as diamonds are the hardest natural substance we think it’s quite fitting.


The only thing that can scratch a diamond is another diamond.


The largest diamond that has ever been found weighed an incredible 3,106 carats which is equivalent to 1.33 pounds, a little heavier then your average bag of sugar. It was called the Cullinan diamond and it was found in South Africa in 1905. The owner of the mine, where this diamond was discovered, gifted it to King Edward. The Cullinan diamond was later cut into 9 large diamonds and 100 smaller diamonds. The three largest diamonds are part of the Crown Jewels on display in the Tower of London.


In 1477 Archduke Maxmillian of Austria gave Mary of Burgundy a gold ring featuring an M spelled out in diamonds, this is the first known use of a diamond in an engagement ring.


Even more incredible is the discovery of a star that weighs around 10 billion trillion trillion carats and about 2,500 miles long. This star is named Lucy after the Beatles song “Lucy in the Sky with Diamonds”. Perhaps one of the most amazing facts of all is the discovery of a planet that Scientists believe to formed mostly of carbon and one third of it being pure diamonds. It was discovered in 2004 orbiting a nearby star in the Milky Way, and named “55 Cancri e”. We wouldn’t mind paying a visit to 55 Cancri e…with some empty suitcases.
