diamonds priced? What makes one diamond more expensive than another diamond?
cut in a range of shapes, sizes and qualities all of which influence
the price. Diamonds that have
an excellent or very good cut grade will reflect maximum fire,
brilliance and sparkle and the price of these diamonds will be higher
than diamonds with a good cut grade.
The Shape of Diamonds
Brilliant Cut Diamonds are the most popular diamonds for diamond
engagement rings followed by Princess Cut Diamonds. Any diamond
that is not Round in shape is known as a Fancy Shape Diamond.
Asscher, Cushion, Emerald, Heart, Marquise, Oval, Pear, Princess,
Radiant and Trilliant cut diamonds are all fancy shape diamonds.
Brilliant Cut Diamonds are the most expensive mainly because when
cutting a Round Brilliant Cut diamond there is a greater loss in
rough which has to be factored into the price. Another reason why
Round Brilliant Cut diamonds are priced higher is because they take
longer to polish and cut than other diamond shapes and the demand for
Round Brilliant Cut diamonds is greater than all the other diamond shapes.
Clarity Influences Diamond Prices The Most
grade of a diamond influences the price obtained more than any of the
other factors. Diamonds that have high clarity grades of VVS1 or VVS2
have extremely hard to find inclusions even with a jewellers 10x
loupe. These diamonds are almost pure and rarer to find than diamonds
with lower clarity grades such as SI1 or SI2 and therefore command a
much higher price. The rarest of diamonds have an Internally Flawless
Diamonds -IF or Loupe Clean clarity grade and these diamonds fetch
Color Influences Diamond Prices
another important factor that influences the price of a diamond.
Diamonds are graded for their colour alphabetically starting at D
colour going down to Z colour. Diamonds that are colourless or show
the least amount of colour obtain the highest prices along with fancy
coloured diamonds such as pink, red, green and blue diamonds.
Diamonds that display the least amount of color are known as
exceptional white. Exceptional white diamonds
includes D and E colour graded diamonds. Rare white is the next
colour grade and this includes F and G colour diamonds. H colour
diamonds are graded as white and I and J colour diamonds are known as
slightly tinted white diamonds.
Cut Influences Sparkle, Shine & The Price of Diamonds
Did you know
that if the diamond is poorly cut, the colour and clarity can not
make up for it? When a rough diamond is cut and polished it obtains
its sparkle and shine. If a diamond is poorly cut, the light that
enters the diamond from above will leak out of the sides and bottom
of the stone, and the diamond will not have the optimum amount of
sparkle or fireno matter what colour or clarity the diamond is.
Ideal Cut Diamonds have been
cut to precise standards to display the beauty of the diamond.
Excellent and Ideal Cut Diamonds have perfection in proportion,
symmetry and polish and they will always display the maximum
brilliance, fire & scintillation.
Ideal Cut Diamonds have properly proportioned facets, excellent
symmetry & polish. Since 97.5% of a diamond's brilliance is
controlled by the quality of the cut Excellent and Ideal cut diamonds
obtain higher prices. The Diamond Cut Grade is made up of three main
controlling factors - Proportion, Symmetry and Polish. The light
return of the diamond more commonly known as sparkle or brilliance is
also an important factor but it is governed by the proportions and
symmetry of the diamond cut.
have a Very good cut grade are able to disperse a good amount of
brilliance because they reflect most of the light that enters them.
Very Good cut diamonds have proportions which often overlap and are
comparable to Excellent cut diamonds but just differ slightly in one
area or measurement. Very Good cut diamonds are also highly valued.
Diamonds are Sold By Carat Weight
Carat is a
unit of measure not size. When comparing two diamonds of the same
carat weight they may appear to be different sizes because of how the
diamonds are cut. Some diamonds will have extra weight on the bottom
part of the diamond, the pavilion, or a thick girdle and therefore
will appear smaller visually.
sold by their carat weight. Diamonds that have a heavier carat weight
also have a higher price per carat. A diamond cutter always try to
retain as much carat weight and as few inclusions when cutting a
diamond in order to obtain the best possible price per carat.
Sometimes the cut of a diamond might be sacrificed in order to
produce a diamond with a higher carat weight. Hundreds of tons of
rock and ore must be processed to uncover a single one-carat gem

have been sorted into their different shapes they are then assessed
with what is known as The 4C's- The Cut, Colour, Clarity and Carat
weight. These individual factors are all combined resulting in the
price of the diamond. The price of diamonds is also influenced by
international market conditions such as exchange rates, supply and
demand, fashion trends as well as inflation.
