The Cullinan is still the largest!

In 1905, the largest rough diamond to date with 3106.75 carats (621.35 g) was found in South Africa and named after the mine owner Thomas Cullinan. The diamond was cut into 105 stones, nine large and 96 smaller ones. The nine large diamonds are now part of the British crown jewels and are in the Tower of London. The largest gem, the Cullinan I, has a weight of 530.2 carats and is called "The Great Star of Africa".

Carat instead of gram

The weight of precious stones - as well as that of precious metals - is measured in carats. The word derives from the Greek "kération", which means "horns" and refers to the croissant-shaped fruit of the carob tree. The seeds of these fruits were used as weights, because it was assumed that the seeds were always the same size and same weight (approximately 0.2 g). In the Middle Ages, one carat was equal to the weight of three barley or four wheat grains.

Without a cut, no sparks

The cut of a diamond not only refers to the diamond’s shape, it also refers to how effectively the diamond returns light back to the viewer’s eye. A well-cut diamond will appear very brilliant and fiery, while a poorly cut diamond can appear dark and lifeless, regardless of its color or clarity. A perfectly cut diamond has both increased brilliance and diameter relative to more deeply-cut diamonds.

Diamonds are forever

Once believed to be tears of the Gods and shards from falling stars, diamonds have captivated the human imagination with their outstanding beauty. The name "diamond" derives from the Latin "diamas", a modification of the Greek "adámas" meaning "invincible".

„Diamonds are a girl’s best friend“

Unforgettably, Marilyn Monroe sang the song "Diamonds are a girl's best friend" in the Broadway adaptation of "Gentlemen Prefer Blondes" in 1953. The song has been covered countless times since then, but the film version of the movie icon is the most well-known to this day, despite the fact that Monroe needed support from the soprano Marni Nixon for the vocals.

Diamonds have more than only a romantic importance

Gems have lasting value, are virtually indestructible, and have a distinct advantage over gold or silver: They take up much less space and weigh a fraction. Large assets can be easily transported in the form of diamonds and stored in a safe-deposit box.
