The green colored diamonds

The green colored diamonds

Diamonds, formed for millions of years, may have undergone natural irradiation during their existence. That's what gives them that green color.

Green diamonds are among the rarest in nature. Their more or less pronounced green hue is due to natural irradiation with uranium present in the subsoil.
Their price varies according to the intensity and clarity of the green color. Some reach really excessive prices.

In June 2016, the green diamond "Green Aurora" weighing 5.03 carats was sold by Christie's Hong Kong to 16.8 million dollars  (source)!


Aurore green diamond

Diamonds of pink and red colors

The presence of hydrogen in a diamond produces violet nuances. Allied with the extreme pressures and subjected to a very high temperature the diamond during its formation, can lead to the creation of a red stone, or pink.
The red diamond is the rarest of all colored diamonds. Only twenty stones have been recognized as being a red diamond.

Red diamonds reach exorbitant prices! In 1987 a red diamond of 0.95 ct was auctioned at a million dollars. In 1996, at Christie's auction another 0.25 ct red diamond of oval size was sold for just under $ 327,000.

Pink diamonds are also very rare in the nature.

The Argyle mine in Australia provides the most beautiful pink diamonds. The others come from mines in Brazil, Russia and Africa (Tanzania).


The red diamond Moussaieff

Famous red diamond


The Moussaieff Red Diamond is the most famous red diamond. His name was before the Red Shield Diamond. Its weight of 5.11 carats and its color "Fancy red", intense red make it the largest red diamond known in the world.
