Purple has been a noble and mysterious
symbol in many places since ancient times. In the Roman Empire, only nobles and
emperors could wear purple; in traditional Chinese concepts, it represents the
spirit of saints and emperors.
Unlike other natural colored diamonds,
the formation of purple natural diamonds is not influenced by chemical
elements, but is the result of the deformation of the diamond crystal. Only in
the process of its formation, the atomic structure of its octahedron is changed
and distorted for some reason, so that natural diamonds show a purple luster,
and its rarity can be imagined.
One of the most famous purple diamonds
in the world today is a heart-shaped diamond named as the Royal Purple Heart
Diamond, which was discovered in Russia and weighs 7.34 carats. It is the
largest known fancy-cut natural purple diamond. The diamond was polished into a
perfect heart shape by Julius Klein, from which the name "Purple
Heart" came from.
Most of the world's existing purple
natural diamonds come from Australia, including the famous Argyle diamond mine.
In 2016, an extremely rare 9.17-carat purple natural rough diamond was
discovered in the area, which is also the largest natural purple diamond ever
found at the Argyle mine.
The rough was cut and polished to become
a 2.83-carat oval-cut natural purple diamond, named the Argyle Violet, and it
became the iconic diamond of the 2016 Argyle Diamond Tender. When it first came
out, it was speculated that it would be worth 50 times the price of an ordinary
white diamond.
Another well-known Argyle Liberté purple diamond, although "only” weighing 0.91 carat, is Fancy Deep Gray-Violet in color and SI2 in
clarity. Argyle Liberté purple diamond is made
in Radiant Cut, a cut commonly used in engagement rings that combines the fire
of a round shape with the elegance of an emerald cut. Such a rich, pure and
brilliant purple makes this natural diamond less than 1 carat a very precious
collection.
In 2017, the 1.64-carat, cushion-cut
"Orchid Fancy Vivid Purple Diamond" exhibited at the Natural History
Museum of Los Angeles was also a rare and precious discoveries in the world.
Unlike the previous two, this natural purple diamond is more inclined to
pinkish purple, and the combination of pale pink and violet tones creates a
unique beauty.
Although they are both called
"purple diamonds", in fact they have two different color
classifications. One is a purple diamond, such as the "Royal Purple
Heart"; the other is a violet diamond, which describes a natural purple
diamond with a grey-blue hue, such as the "Argyle Violet Diamond."
To date, the combined annual global
production of purple natural diamonds is less than 100 carats. There is no
doubt that it is yet another "miracle" of nature. Although most
natural purple diamonds only have a slight purple tinge in pink or blue, but it
is the most beautiful embodiment of preciousness and elegance from the moment
it blooms.
