A Beginner’s guide to Diamond Cuts
The world of diamonds can sometimes be a confusing place, so this week we’re demystifying everything about Diamond cuts, so you know exactly what to look for when you're choosing your unique diamond engagement ring.
Diamond cut means two things:
First off, a bit of a
confusing start, as the diamond industry actually uses the word "cut"
in two different ways.
Most commonly, it's
used to describe the shape of a diamond (for example, a "princess
cut" diamond).
The second way
"diamond cut" is used is to describe the reflective qualities of a
diamond. The reflective quality of the diamond is determined by how well the
diamond was cut. Got it?
This second usage
(the reflective quality) is the one that is graded and gets the score on
diamond certificates which are issued with your diamond ring purchase.
The cut of a diamond
determines the angles and finish, which lends to its ability to handle light,
which is commonly referred to as its ‘brilliance’. The sparkle that you see
(and turns heads), when the diamond catches and refracts light.
A little bit more about light
When a diamond is
well-cut, light enters through the table (the top of the diamond) and travels
to the pavilion The space between the bottom of the diamond up to the widest
point), where it reflects from one side to the other before reflecting back out
of the diamond through the table and to the observer's eye.
In a badly cut diamond, the light that enters through the table reaches the facets and then 'leaks' out from the sides or bottom of the diamond rather than reflecting back to the eye. Less light reflected back to the eye means less brilliance.
The GIA (Gemmological
Institute of America) is a renowned and well-respected diamond grading entity
that issues report for the cut of diamonds, which the is the very system Hatton
Jewels uses to certify its diamonds.
As an independent
entity, GIA does not have a financial stake in the sale of the diamond. When
you are in the market for diamonds, it’s advisable to seek a GIA certificate to
view the Diamond’s Cut grade.
Excellent Cut
Diamonds provide the highest level of fire and brilliance. Because almost all
of the incoming light is reflected through the table, the diamond radiates with
magnificent sparkle.
Very Good
Very Good Cut
Diamonds offer exceptional brilliance and fire. A large majority of the
entering light reflects through the diamond’s table. To the naked eye, Very
Good diamonds provide similar sparkle to those of Excellent grade.
Good
Good Cut Diamonds
showcase brilliance and sparkle, with much of the light reflecting through the
table to the viewer’s eye. These diamonds provide beauty at a lower price
point.
Fair
Fair Cut Diamonds
offer little brilliance, as light easily exits through the bottom and sides of
the diamond. Diamonds of a Fair Cut may be a satisfactory choice for smaller
carats and those acting as side stones.
Poor
Poor Cut Diamonds
yield nearly no sparkle, brilliance or fire. Entering light escapes from the
sides and bottom of the diamond.
However, one thing to
note is that around 55% of all round cut diamonds (the most popular choice of
diamond) receive an excellent rating.
For a truly assured
purchase, we recommend you always see a diamond in person before buying and
speak to a knowledgeable GIA qualified gemmologist. Hatton Jewels small team
are all GIA qualified, so feel free to drop us a line if you have any questions
