One of the 4Cs includes diamond colour, which impacts its appearance as
well as value. In a highly common phenomenon, when light hits and enters the
diamond, most of it is reflected back to our eyes in ‘rainbow’ colour patterns.
This phenomenon, known as the fire of the diamond is usually reduced when the
stone has visible colour in it, decreasing its reflection capability.
Here are all the ways how you can search for visible colour in a
diamond, which affects its sparkle, fire, and value.
In general, diamonds are famous for being crystal white as they reflect
more than 80% of the light that enters them (based on their cut). However, you
must have come across several stones that look far from the white bright and
elegant diamonds that you’re so fond of, but why so? Because diamonds come in
several shades, including pink, blue, and yellow.
Although the idea of colourful diamonds sounds interesting, the presence
of the yellow tint in a white diamond acts as a ‘deformity’, thereby lowering
the stone’s market value. In simple terms, a diamond with less body colour will
reflect more true light, in turn increasing its value.
Let’s take a deeper look into the world of diamonds and their variety of
shades.
Every diamond in the world has been assigned a colour grade by
Gemological Institute of America (GIA) depending upon the shade they possess.
Grading of stones in such a way helps in determining the diamond value and
their usage. Thus, while a diamond may not be certified by GIA, every diamond
that makes it to the market is graded based on GIA’s grading chart.
It is pretty standard across the globe. The grading scale starts from D
(colourless) and goes all the way to Z (light colour). The colour-grading of
the diamond is based on the stone being colourless. So, if a stone carries less
or no colour, they are graded higher in the scale. Interestingly enough, all
the diamond stones from grade D to Z are termed under ‘white diamonds’ even
though they contain a varying degree of colours to themselves.
Note: Fancy coloured diamonds, such as pink, blue,
and yellow, are graded on a separate scale.
A Quick Overview of Diamond Grades
D is the highest diamond grade, and the stones belonging to this grade
are almost as clear as water and ice. They reflect the maximum amount of light
that enters them. The grade E and F contain slight traces of colour in them,
which can only be detected by an expert eye, i.e. a gemologist. Evidently, the
diamonds that fall under D, E, and F grade are rare in the world and carry
hefty price tags along with them. They often go well with white gold or platinum as yellow gold or rose gold might turn the attention away from the
diamond’s brilliance.
Same as its name, the stones falling under this section of grade display
nearly zero colours in them. The diamonds appear clear and without any traces
of colour by the naked eye and often require a keen observer or a tool to
capture the shades that might be in the stones; their less than perfect appearance
even makes them moderately expensive. The diamonds graded G and H are good for
platinum and white gold, while I and J graded stones can be mounted on yellow gold.
This grade of diamond possesses a faint tint of yellow shade that is
visible with the naked eye. You can clearly differentiate between higher-grade
diamond and this grade diamond by comparing them with your eyes. As a result,
they are less desirable and do not cost a fortune, although they can still be
used as jewellery along with yellow gold and rose gold.
They have almost nil reflection as compared to above-mentioned grades.
These stones have very visible colour in them, often yellow and brown.
Subsequently, their market demand, as well as market value, is less, making
them less desirable for jewellery making.
These lowest grade diamonds are easily noticeable to carry yellow or
brown tint. They are the least expensive diamond and considered unfit for
making any kind of ornament.
As per the explanation above, you must have understood how diamond
grading is essential to know the market value and demand. No one wishes to buy
diamond jewellery that possesses less brilliance and no elegance. Thus, the
diamond value in the market is based on how clear, brilliant, reflective, and
colourless a diamond is.
For instance, a diamond that falls under grade D, E, and F is likely to
have high value and demand owing to its colourless structure and brilliant
reflection. In simple terms, the higher the position of the clarity grade, the
more expensive and elegant will be the diamond. However, in such cases, you
need to ensure that the diamond of your liking is within your budget before you
finalize on buying it. For the safer side, you can usually go till grade K, L,
and M, if you’re thinking of shopping diamond mounted on yellow gold.
There are a few necessary tips that you must follow if you’re thinking
of buying a diamond for the first or even the nth time.
Always focus on the colour of the diamond. Take the stone in your hand,
tilt it in different light sources, and see if there is any visible colour
spots or tints in it. While you can always buy the diamond if it has faint
shade, but try to keep your stone choice between the D to M, based on your
budget.
Secondly, focus on the diamond cut as well. While colour determines the
sparkle and brilliance of the diamond, it is the cut that finally has a say in
the stone’s overall colourless and brilliant appearance. So, always look for
the combination of cut and colour while buying a diamond.
Always pay the right price, and how can you do that? By obtaining the
certifications that prove the authenticity and originality of lab tested and
analyzed diamond.
Lastly, choose the right set of setting to go with your diamond. For
example, a white gold mounting will look amazing for a high-grade diamond, and
yellow gold mounting will appear to be good for faint coloured diamond stones.
