The pink diamond is the world's most
rare and valuable diamond.The
Argyle mine is the world's foremost
source of unrivalled intense pink diamonds,
producing 95% of the world's supply.
However, an extremely small proportion
of Argyle Diamonds production is Pink
colour, in fact less than one tenth
of 1% is classified Pink.
legend of Argyle pink diamond has grown over
the past ten years. At the 1989 Christie's
auction in New York a 3.14 carat Argyle pink
sold for $1,510,000. Privately, Argyle has
sold pink diamonds for up to $1 million a
years the white diamond was considered
the world's most beautiful diamond,
until the discovery of the Argyle mine
heralded the arrival of the Argyle pink
diamond. Never before had pink diamonds
displaying such intense shades of colour
been seen. The pink diamonds of India,
Brazil and Africa were characteristically
light in colour and paled even further
when placed beside the intensely pink
Argyle diamonds. The natural colour
diamonds have in fact been around as
long as the classical whites but in
much smaller quantities and never in
Argyle pink diamond comes in shades ranging
from delicate pastel rose to robust raspberry
and full-blooded purple-reds. The prices per
carat are determined by the intensity of colour.
Argyle selects only its most vibrant pink
diamonds for polishing at its head office
in Perth. There, the stones are polished in
a wide range of cuts, such as round brilliant,
marquise, oval and pear, to enhance their
natural beauty. Polished pink diamonds are
available in the same size ranges as traditional
commercial sizes.|| |
a year, Argyle Diamonds issues a special
release of outstanding pink diamonds
that are sold by special bids in the
international and invitation-only, Pink
White diamonds are produced by mines
all over the world in a wide variety
of shapes and sizes.The
white diamonds recovered from the Argyle
mine are particularly brilliant and
of high quality.
diamonds with secondary pink colour
Argyle mine also produces white diamonds
with secondary pink colour that command
a higher price per carat. In an effect
similar to that described of pink champagne
diamonds, the white diamond will display
slight to bold flashes of pink when
viewed from the top. A higher price
is commanded for pink secondary colour
depending on its depth and strength,
because pink is one of the most rare
colours found in diamonds.
Champagne diamonds are naturally coloured
diamonds that are produced in a wide
range of colours from light straw to
4C's of colour, cut, clarity and carat
weight apply to coloured diamonds just
as they do to colourless diamonds except
the intensity of colour, not lack of
it, plays a greater part in the valuation.
Diamonds created the following scale
specifically for champagne diamonds.
The diamonds are graded on a C1-C7 colour
scale. C1 and C2 represent light champagne,
C3 and C4 medium champagne, and C5 and
C6 dark champagne. The fancy cognac
diamond is graded C7.
Attractive champagne diamonds with secondary
pink colour are also available and command
a higher price per carat than champagne
diamonds. These stones display slight
to bold flashes of pink in their fire.
Pink Champagne Diamonds are available
in three ranges of shades, from light
pink champagne to medium and dark pink
pink is one of the rarest colours found
in diamonds, even secondary colours
demand a higher price depending on depth
and strength of colour.
Fancy yellow diamonds come in a broad
range of shades ranging from light yellow
to a rich canary colour.

of the sky to a more "steely" colour

Usually, penetration of the colour is
not very deep and is often removed during
the fashioning of the stone.

Cubic Zirconia (CZ) is the most commonly
encountered diamond simulant. All commercial
CZ is formed in laboratories however,
it is also found in nature. In both
its synthetic and natural forms, CZ
is colourless but colour can be introduced.
A thermal pen tester can quickly and
easily detect CZ.
Synthetic moissanite is a new diamond
simulant to join the long list of products
that imitate diamonds. Although moissanite
is being marketed as a new unique, synthetic
gemstone, some of its properties are
close enough to those of diamonds to
lead to confusion in the trade.
moissanite was first identified in a
meteorite crater at the beginning of
the twentieth century however, most
is produced synthetically as natural
moissanite is very rare. Chemically,
it is 'silicon carbide', also known
as 'carborundum', which is widely used
for abrasive purposes and for use in
the electronics industry.
Synthetic moissanite is a diamond simulant
like Cubic Zirconia however, it can
be passed as a diamond by the widely
used thermal pen testers because it
has similar thermal characteristics
to diamonds. However, it can be easily
identified by other methods.
