How to Buy a Diamond

Some facts about diamonds:

About 2800 years ago in India, the very first diamonds were mined.  These diamonds, and most of the diamonds we find today, are about 900 million years old (sometimes even older, the oldest diamond found is dated as being 3,2 billion years old).  Many people do not know this, but diamonds are in fact as unique and different from each other, as snowflakes.  This means that you won’t find any 2 diamonds on earth that are alike.  That makes an engagement ring THAT more special don’t you think?  Before you go rushing to the shops to get the first and best diamond, do some research on how to buy a diamond first.  Never ever buy diamonds unless you know at least a little about the cut, weight, shape etc., so let’s explore this gem a little further.



 How diamonds are priced.  Introducing the four C’s

 When considering buying a diamond, you need to familiarize yourself with how diamonds are “valued” by jewelers around the world.  Each aspect of the four C’s contributes independently to the overall price of your next diamond.  Here they are:

  1. Color
  2. Clarity
  3. Cut
  4. Carats

 How to Buy a Diamond based on Color:

Diamonds can come in an array of different “shades” including pink, green, blue and yellow.  Although the actual color of your diamond is entirely a personal preference, the colorless diamond (also known as “white diamonds”)  are the most expensive due to being the most rare.



How to Buy a Diamond based on Clarity:

The first thing you want to look for ,  is dark spots that are found inside the diamond.  You would need a magnifier to see this though, because some of these can’t be seen with just the naked eye.  Clarity of diamonds is in essence self-explanatory.  The clearer the diamond is when looking through it with magnification, the more it will cost.  A Flawless diamond is very rare due to the fact that almost all diamonds have their own unique “flaws” and/or inclusions, such as the dark spots mentioned above.



How to Buy a Diamond based on Cut:

The better the cut, the more valuable the diamond becomes.  A Poor cut means that the diamond is less shiny and brilliant.  How the diamond is cut, is up to the artisan.  The artisan angles the gemstone in such a way to best reflect light through it, in order  to make it sparkle.  The true beauty of the diamond will only be visible by a quality cut.  Diamonds loose about half of their initial size when cut and polished.

 How to Buy a Diamond based on Carats: 

Carat refers to the mass of the diamond.  The more carats, the heavier the diamond, which in turn means a more expensive gem.  When you come across 2 diamonds that are equal carats, the bigger one will be more expensive due to their scarcity.  Here is an example:  even though you buy a ring with 3 diamonds set in it, adding up to one carat, a ring with a single diamond weighing one carat, would be the more expensive ring.


Final thought on how to buy a diamond.

Now that you read and understand the all important four C’s, there is one other thing you can pause on.  If you are very interested in a particular diamond, it would be a good idea to have the diamond professionally certified and appraised by an independent organization.  Many jewelers offer appraisals and certification “in-store”, but these are often found to be slightly higher than the diamonds’ actual worth.  This is quite logical due to the fact that the jeweler selling the diamond could be biased and may value the diamond higher in order to gain more money from its sale.

We hope this guide helps you when thinking about buying a diamond.
