The value of a
diamond is determined by 4 characteristics known as “The 4 C’s”. These are: Cut, Carat,
Colour and Clarity.
The way a Diamond is cut dramatically influences how much fire and life it
has and how much it sparkles. In a well cut Diamond, the maximum amount of light is
reflected back up through the table of the stone, releasing its beauty. All our Diamonds
at ABSOLUTE DIAMONDS are of the finest export quality.
Cut also refers to the shape of the diamonds, and this reflects
upon the price, while cuts such as a brilliant have slightly higher price tags, a cut such
as a emerald cut will be a bit cheaper
A Carat is the unit of measurement used when
weighing a diamond. One carat is the equivalent of 0.2 grams. A diamonds’ value is
greatly determined by its weight. For example if you had two identical diamonds i.e. same
colour, clarity and cut but the one weighs 1 carat and the other only half a carat, the 1
carat diamond may be worth as much as 350% more than the half carat!
carat refers to the weight of the diamond and not its size. Bigger is not always better or
more expensive when considering a diamond purchase, although diamonds larger than a carat
are generally considered rare and of greater value per carat. EG:a large H I1 will cost
less than a small D flawless .There are 100 points in a carat (25 points = ¼ carat)
A diamond’s colour is graded in a range from D-Z.
D being truly colourless and of the highest quality. E and F are also graded as colourless
while G, H, I and J are near colourless. Stones grades K, L, and M will have obvious hints
of colour and as the scale approaches P you may find subtle changes in hue and tone.
The exceptions to the rule are "Fancy"
diamonds in colours that include pink, blue, orange, green, and canary yellow. These are
particularly rare and very valuable.
Colour determines the rarity and value of a diamond
and the "best " colour for a diamond is no colour, which allows the stone to
cleanly reflect light. Diamonds with no colour (colourless) are very rare and you'll find
them to be very expensive. Most diamonds used in jewellery are nearly colourless with
faint yellow or brown tints
Diamonds have been formed over
millions of years through "crystallisation" and most contain small inclusions or
imperfections. They appear in the form of small specks and generally are only visible with
a jeweller's loupe. The fewer the inclusions, the better the quality and higher the cost.
Diamonds are cut in the
following standard shapes:
