Tips for Choosing
How to purchase diamonds
based on the 4Cs of diamonds
Owing to the nature's lengthy process of creating diamonds out of carbon, most
diamonds are much older than one would think. It is estimated that most of the diamonds we find today are at least
900 million years old. Experts believe that the oldest known diamond is around 3.2 billion years old.
But it took a while before people started mining diamonds and realizing their intrinsic value. It was more than 2800 years ago that the first
diamonds were mined in India. Since then diamonds have been found in many different countries. Major diamond mining
countries are: Australia, DR Congo, Botswana, South Africa, and Russia. Annually, some 130 million carats of
diamonds are mined worldwide.
|The process of choosing diamonds involves many
factors, but the
most important ones are the 4Cs: cut, clarity, carats and colour.
Each diamond is unique
Each mined diamond is completely unique. To the trained eye, one can find that
there are no two diamonds that are precisely the same. This is what makes each diamond so unique and
When learning how to purchase a diamond, there are many things to
consider. Until you know more and have done your research, you should never rush into buying a diamond. It’s
especially important to learn how diamonds are priced.
What the “4 C's” mean for the value of a
When buying a diamond, you have to consider many different factors. Throughout the
world, though, there is an established method that jewellers use as a way of defining the value of a diamond. The
method is known as the “4
C’s”. If you are interested in understanding how to buy a diamond, it
would help to know exactly what the 4 C's are and how each aspect of the diamond contributes to its
The 4 C's represent Cut, Clarity, Carats and
Based on the 4Cs of diamonds, the value of a diamond is determined by its: cut,
clarity, carats and colour. We'll go in more detail on each of these value measures for a diamond.
1. How to Buy a Diamond based on
The cut of a diamond is a description of how the diamond maker angles the gemstone
in such a way as to best reflect light through the diamond, resulting in the diamond’s sparkle (sometime referred
to as diamond's brilliance). A high quality cut enhances the innate beauty of a diamond and increases its value. A
poorly cut diamond isn't as brilliant or shiny and, therefore, will be less valuable.
2. How to Buy a Diamond based on CLARITY:
The clarity of a diamond involves looking at how clear the diamond is when you
look through it. Most diamonds have inclusions and flaws and it is rare to find a perfect diamond. Flaws, however,
cannot usually be seen without magnification. When purchasing a diamond for clarity, look for the presence of dark
spots inside the diamond. Although flawless diamonds are naturally of the highest value (all else being equal), buy
those with flaws that can't be seen by the naked eye, if you are looking to purchase a diamond that looks good, but
3. How to Buy a Diamond based on CARATS:
Carat defines the size of the diamond. Larger diamonds (those of a higher carat)
will cost more than a cluster of smaller diamonds, even if the total carats of the diamond cluster are the same.
This means that a single one-carat diamond will cost you more than three diamonds set in a ring that add up to one
carat. The reason behind this is that larger diamonds are rarer than smaller diamonds, thus more expensive. This is
also unfortunately impacted upon by the fact that diamonds lose about half their size during the process of
4. How to Buy a Diamond based on COLOR:
The colour of diamond you choose is entirely based upon your personal preference.
Diamonds that are colourless, however, are the rarest and therefore cost more than other diamonds. Colourless
diamonds are also known as white diamonds. There are also fancy colour diamonds. These come in a variety of
different hues, including yellow, green, blue and pink. There are even diamonds known as “black diamonds”. It's all
to do with how the light is reflected through a diamond.
Certificates and Appraisals
While understanding the 4 C’s in determining how to buy a diamond, you should also
learn how to read diamond
certificates. These certificates describe in detail the facts about the
diamond in its unmounted state.
Perhaps you have a specific diamond you want to have professionally appraised by
an independent organization. This is probably not best done by the jeweler you are buying the diamond from, because
they are often biased and may appraise the diamond at a slightly higher value than what it’s actually worth in
order to receive more income from the sale of the diamond.
