Diamonds
Golconda & Type IIa Diamonds
All diamonds can be classified into two main categories which are referred to as ‘types’,
depending on the trace elements that are naturally present within the carbon crystal structure
of the diamond.
Type I diamonds contain small amounts of nitrogen whereas Type II diamonds do not. Each of these types is then subdivided further and
the term Type IIA is used to denote the very purest diamonds. This means
there are no measurable impurities in the diamond of any kind which makes these stones
exceptionally rare, they make up less than 2% of all gem quality diamonds found worldwide. Not
only can these stones be perfectly colourless but they also possess an exceptional level of
transparency which enhances their beauty and allows the brilliance and fire of the diamond to be
appreciated to the fullest. Famous examples of Type IIA diamonds include the Koh-i-Noor and the Cullinan, which are part of the Crown Jewels, as well as the Krupp diamond which Richard Burton
bought for Elizabeth Taylor and was later renamed the Elizabeth Taylor
Diamond.
The design of the French cut had developed from the addition of extra facets to old table cut
diamonds thereby altering them into much more lively stones.This style of cut has changed very
little to this day and its evolution marks one of the earliest milestones in the development of
the brilliant cut diamonds we know today.
Coloured Diamonds
Coloured diamonds or Fancy diamonds as they are also known, have become increasingly popular
over recent years and are available in a beautiful range of colours from yellow and pink to blue
and green.
Colour in diamonds can be caused either by a structural anomaly or by elements such as nitrogen
or boron replacing carbon atoms within the crystal structure of the diamonds. In yellow diamonds
it is nitrogen which is responsible and the strength of colour depends on how much of it there
is, and also what form it has taken. When a coloured diamond is graded for certification by the
GIA, the saturation of colour will be judged and one of the following grades will be assigned:
Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Dark and Fancy
Deep.
White diamonds (graded from D colourless through to Z pale yellow, known as Cape diamonds)
decrease in cost the more colour they display because they are valued for their lack of colour,
i.e. their whiteness. However, the reverse is true for Fancy diamonds which will increase in
cost the stronger and more vibrant the colour they display. We curate our coloured diamonds very
carefully and always choose the most attractive of hues whether it is a Fancy diamond or Cape
diamond.
Old Mine Brilliant Cut
Old mine brilliant cut diamonds are sometimes referred to as old miners or OMBs and are either square or rectangular diamonds with obviously rounded corners and sides.
This softened profile is called a cushion shape as the convex edges and curved corners are said to resemble an actual cushion.
The style developed during the 18th century after the discovery of diamonds in Brazil in about 1725.
This facilitated experiments in cutting due to the large increase in available stones.
Eager as ever to retain as much weight as possible, cutters still followed the overall shape of the rough crystals but now corners became more rounded and the number of facets were increased.
The profile proportions of the stones also echoed the rough with the crowns being relatively high and the top table facet generally fairly small.
Another typical feature of these stones is the point at the bottom of the stone, known as the culet, which was polished flat.
The discovery of diamonds in South Africa during the late 1860’s coincided with revolutionised mechanical cutting methods.
This saw the fashion for new circular cut diamonds begin to replace these cushion shaped stones which then became known as ‘old mine’ diamonds.
Today the name ‘old mine brilliant’ still describes a cushion shaped diamond with a small table facet, high crown and polished culet.
These features enable old mine cuts to display a huge amount of fire (the coloured flashes of light you see in a diamond) and life.

Carat
The term carat refers to the weight of a diamond which naturally impacts its size.
One carat is equal in weight to a fifth of a gram and each carat can be divided into one
hundred points.
Therefore a diamond weighing one and three quarter carats would be written as 1.75
carats and one weighing 0.70 carats would be said to weigh 70 points.
The term ‘carat’ comes from the word carob because historically the seeds of the carob
tree were used by traders as a means to judge the weight of gemstones.
The seeds of this tree were relatively uniform in weigh at around 0.2 grams so they were
used as a comparison to gauge the weight of gems.
Today, this C is often the first thing someone asks about but it is worth remembering
that not all diamonds that weigh the same will look the same size to
the eye because it will depend on the cut of the stone and particularly its depth.
With regards to the impact of weight on price then the price per carat will obviously
rise as the carat weight increase.
However, it must be noted that as larger diamonds are rarer than smaller ones the price
does not rise evenly,
for example a 2ct diamond is not simply double the price of a 1ct diamond.

Colour
Perhaps a little confusingly, the colour of a white diamond is actually judged by its
lack of colour. The vast majority of diamonds have a slight hint of yellow to
them, some more noticeable than others. The less of this yellow tint a diamond has, the
whiter and rarer it is. Diamonds are colour graded using an alphabetical
scale starting at D (pure white) moving sequentially down the alphabet to Z (light
yellow). It is the presence of nitrogen within a diamond that causes the yellowish
tint, the more nitrogen, the more yellow the diamond will appear.
In terms of how this affects price, essentially, the whiter the diamond and higher the
colour grade the greater the value of the diamond. However, it is important to
remember that a lower colour grade does not equate to a lower quality, the grade is a
measure of rarity, the whiter stones are simply rarer and therefore command
higher prices.
The chart below shows the colour grading scale used by the GIA, the Gemmological
Institute of America.

Clarity
The term clarity refers to the presence of small inclusions inside the diamond or
blemishes on its surface. These are a natural part of the diamond and include
features such as tiny crystals and feathers. For the most part these formed with the
diamond billions of years ago during its creation deep in the earth’s mantle
under intense heat and pressure. The clarity grading scale ranges from ‘Flawless’ down
to ‘Included’. Determining a clarity grade depends on several considerations
such as how many inclusions a diamond has, how big they are, what sort they are and what
position they are in i.e. right in the centre of the stone or over at the
edge.
All these factors are taken into account and a judgement is made as to how detrimental
they are to the overall appearance of the diamond. It is worth remembering
that, unlike colour grading, clarity grading is done under 10x magnification with a
microscope so any inclusion in a diamond will be far less noticeable to the naked
eye than it is to the diamond grader. Ultimately the cleaner the diamond, the fewer the
inclusions and less impact they have – the better the clarity grade will be.
The table below shows the grading system used by the GIA.
FL
Flawless
No inclusions or blemishes of any sort are visable to a skilled diamond
grader using 10x magnification.
IF
Internally Flawless
No inclusions and only blemishes are visable to a skilled diamond grader
using 10x magnification.
VVS
Very Very Slightly Included
Inclusions are difficult for a skilled diamond grader to see using 10x
magnification.
VS
Very Slightly Included
Inclusions are noticeable to a skilled diamond grader to see using 10x
magnification.
SI
Slightly Included
Slight inclusions are noticeable to a skilled grader using 10x magnification.

Cut
The term cut is often used to refer to a diamond’s overall shape or style of faceting
but when it comes to diamond grading, what matters is the quality of the cut
rather than its style. We are looking to judge the particular sizes and angles of the
facets (the flat faces polished onto a gem) and their relationship to each other
because it is this, more than anything else, that will dictate the life, sparkle and
overall beauty of a diamond.
The proportions of a diamond affect the way it interacts with the light that enters it,
determining how much of that light is returned to the viewer. A poorly cut
diamond will allow light to leak out of the back and will look dull in comparison to a
well cut one that will return the most amount light and therefore look bright
and sparkling. There are several factors that a GIA diamond grader will assess before
assigning a cut grade. The three below have the most impact on the overall
appearance of the diamond to the naked eye when viewed face up, ie through the table.
1. Brilliance: This refers to the reflection of white light from both the surface and
the inside of a diamond.
2. Fire: This is the term we give to the coloured flashes you see in a diamond resulting
from the splitting up of white light into its spectral colours.
3. Scintillation: This is the sparkle a diamond displays, the pattern of light and dark
flashes caused by reflections of light as a diamond is moved. Other
considerations include symmetry and the quality of the polish which impacts how well the
light reflects off the surface of the diamond.

The Silent 5th C! Certificate
For diamonds, the only laboratory we trust for certificates is the GIA (Gemological
Institute of America) so you will find all our diamonds over 0.75cts come with a GIA
certificate as standard. This means that you don’t just have to take our word on the
quality of the stone you are looking at, you have an independent expert opinion in black
and white that will be yours to take away with you at point of purchase. This will
confirm the colour, clarity, carat weight and cut grade of the diamond, features known
as the 4 C’s. If you are unfamiliar with these characteristics, we have explained them
all here (Henry – can this be a hyperlink to the 4C’s info page) along with how they
impact value but not necessarily beauty.
