How to choose the perfect diamond for you

We know that purchasing a diamond can seem like an overwhelming task. With the myriad options in shape, colour, and clarity, how can you be sure you’re buying the right diamond? The following info is a laymans guide to help you understand the  4c’s grading process.

First and foremost it is important to remember that the 4 C's are only a guideline.


Cut is the most important of the 4C’s to understand. The brilliance of a diamond depends heavily on its cut. It is essential to its beauty. Cut refers to the cutting grades of the diamonds proportions, polish and symmetry and each grade is divided into 4 categories:

Excellent, Very Good, Good and Fair.

A diamond’s cut determines how the diamond shines, how it reflects light and creates that dazzling combination of Fire and Ice, that amazing sparkle, that diamonds are highly prized for.  We at E-Jewels consider a diamond’s cut the most crucial aspect of the quality of a diamond.

A lot of people make the mistake of confusing cut with the shape of a stone. Brillant-cut, Oval-cut, Princess-cut,

 this refers to the shape the stone is cut into! 

In diamonds the colour charts start with D. The colours are graded on an alphabetic scale from
D (exceptional white /colourless) through to Z (heavy yellow).  Note – there is no colour grade higher than D.  
Colour Description

These are the top colours in the colour grading scale and are in fact colourless, they are quite rare and this is reflected in their cost, a lot of shops will convince you to buy these colours but they are quite costly.

If you are operating within a budget constraint, it means you will have to sacrifice elsewhere, usually on the carat weight which means a smaller stone.

 G-H These colours are next in line in the colour grading scale. They are the middle of the range colours, shine white and are therefore the most popular colours on the diamond scale.
They are good
value for money but due to recent market changes people are now requesting these colours more and more which means they are starting to rise in price.
 I These colours have become most popular in recessionary times -Although depending on the individual stone I colours are very close in colour to H's. So it can look like a H but have the cost of an I. Which is quite significant price wise!
Visually to a layperson it would be hard to spot the difference.
These stones are what we at E-Jewels refer to as 'more flash for less cash' and are very
budget friendly indeed!  In fancy shape especially in Oval shaped diamonds, Emerald cut diamonds and Cushion cut diamonds because of the way they are cut an I colour can be yellowish.
 J-K Diamonds graded as J - K colours have a slight yellowish tint - In saying that some J's can look white! It depends on the stone.
K colour, stones go from very slight yellow to very noticeable yellow or brown tints down the colour scales to “fancy” coloured diamonds or “champagne” coloured diamonds.
These stones are cheap and often sold in Antique shops.

Diamond colors

Note:     Fancy shapes can show colour more easily. For example in Princess cuts, Oval cuts, Cushion cuts, Marquises.... colour can be seen more easily than in a round/Brilliant-cut stone of the same colour due to the shape/cut of the stone. Therefore when purchasing Fancy shapes colour plays an important part and is a necessary factor to consider.

Most natural diamonds have inner flaws or inclusions that occur during its’ formation over time, the degree, the amount and the visibility of these inclusions determines their clarity and as a result influences their cost.  There are diamonds completely free of all inclusions, these are most rare and are graded as Flawless or Internally flawless. These are very expensive and are often purchased as investment diamonds.
Inclusions can detract from the diamond’s clarity and value. Of course, depending upon where the inclusion is located, how many there are and how visible it is, it may have little to no impact on the diamond’s ability to reflect light. Mostly, inclusions are only detected by means of a hand-loupe (eye-glass) with a
10x magnification. As most people don’t go around with a hand-loupe in their pocket, we will provide them with a loupe to view their diamond in order to know what clarity grade their stone is.

Clarity Grade Description
FL-IF-LC Flawless/Internally Flawless/Loupe-Clean   
Very rare and quite expensive.
VVS1-VVS2 Very, Very Slightly Included. Inclusions are difficult to see even under high 10x magnification.  
Excellent quality.  Also Expensive.
VS1-VS2 Very Slightly Included.  Inclusions are not visible to naked eye. Reasonable prices compared to VVS1 and VVS2. 
SI1-SI2 Slightly Included
Some Si1's can be very close so Vs2's  depending on where the inclusions are! These are Value-priced diamonds!
Whereas some Si2's can be very marked and possibly visible to the eye! There are some 'nice si2's but these are rare.  Be careful when choosing these diamonds...
PI1 – PI3 Heavily to very heavily Included.  Visible to the naked eye.  
Not recommended by E-Jewels. A lot of this quality is sold in New York and Dubai!

Aside from carat weight, clarity has the 2nd most impact on a diamond’s selling price. To give you an idea of how to identify a diamond’s clarity grading system, see the diamond grading chart below.

Carat (weight)....
After carefully considering your diamond’s
cut, colour and clarity, it’s time to think about the size, or carat weight, of the diamond. Carat weight greatly determines the value of a diamond as well as the overall presentation of the diamond when set in a ring.

The weight of a diamond is measured in carats. A carat is equal to 0.2 grams, or 200 milligrams. A carat is divided into 100 smaller units called points. For example, three-quarters of a carat is 0.75 points or ¾ carat.

When a diamond cutter is cutting a stone, it is his intention to achieve one of the following target weights; ½ carat, ¾ carat, 1.00 1.25 carats, 1.50 carats, 1.75 carats, 2 carats etc.  These are the carat weights that most consumers are familiar with and seek out when shopping for diamonds. However, diamonds are available in weights that fall between these weights, often for a bargain price.
