The Four C’s of Buying Diamonds

Diamonds are the most expensive gem and when shopping for it you need to look at the basic attributes that are highlighted in the diamond's 4C’s – cut, color, clarity and carat.

Cut: A cut defines the facet arrangement of diamond that is further called as Shape. People get confused with cut and shape. But, they are two different aspects of the same coin. Basically, the craftsman shows his skills by arranging the facet of the stone in such a way that the light which enters through diamond should get reflected directly back to the viewer's eye.

Diamond cutters are solely responsible to make or break the light that enters through the stone. Hence, too shallow or too deep cut can cause light to "leak" out from the sides and bottom of the diamond.

GIA has set parameters that evaluate diamond cut and grade them as follows:

* Ideal
* Premium
* Very Good
* Good
* Fair and Poor.

The better the Cut grade, the more expensive is the diamond.

Color: Here the color refers to the transparency of the gem, because colorless diamonds are more valuable than a colored stone. With the exclusion of "fancy colored diamonds", colorless diamonds are very rare and highly in demand. Diamond color has been graded on a GIA scale from D (colorless) to Z (light yellow). 

Clarity: It refers to the internal flaws that are called as inclusions such as small flaws, air bubbles, scratches, tint or other minerals within the diamond. The inclusion of diamond would result on its price. However, diamond with less inclusions is more precious and attractive.

The scale for grading diamond's clarity is:

F Flawless – No inclusions.

IF Internally Flawless - Slight inclusions in the exterior of the gem.

VVS1-VVS2 Very Very Slightly Included - minute inclusions that are very difficult to detect on 10x magnifications loupe.

VS1-VS2 Very slightly included - tiny inclusions, invisible to the naked eye and can only see through the 10x magnification loupe.

SI1-SI2 Slightly included - invisible to the naked eye, yet easily visible under 10x magnifications.

I1-I3 Included - inclusions are visible to the naked eye and affect on its brilliance.

When deciding on clarity, people usually go with SI2 and VS1 diamonds, without knowing their differences. A diamond that falls between VVS2 to F is very rare and expensive so, make sure you select the stone with proper evaluations.

Carat: A carat refers to the size and actual weight of a diamond. One carat is equivalent to 200 milligrams. Carat is also evaluated in numerical values.

For example:

* One carat diamond equals to 100 points,
* One-half carat diamond is consider as 50 points
* Three-quarter carat diamond as 75 points and so on.

Big diamonds are more expensive than smaller one of the same quality because of its rarity. For example: one carat diamond is much more expensive than value of multiple small diamonds of the same quality and total carat weight.

How to analyze a diamonds color

Diamond evaluation can be done on the basis of four C’s – Cut, Color, Clarity and Carat as they are considered the most important attributes. However, diamond color is one of the main aspects that you need to look at while purchasing a diamond. The basic knowledge of the diamond in terms of 4c’s makes your investment worthwhile.

Diamond Color Variations:

A colorless diamond is more valuable than a colored diamond because it impacts its prices. The Gemological Institute of America (GIA) has set a standardized method to grade a diamond color. The diamond color has been analyzed on the basis of its colored stones that could be specified through the grading procedure.

Diamond Color Grading Procedure

a) Color grading is done on loose diamond because once the diamond is placed on metal then it is difficult to detect the amount of color the stone has.

b) 10X magnification loupe is used to locate the amount of color in white diamonds

c) GIA grading scale categorizes the diamond color in alphabetical order from D to Z

Diamond Color Grading Scale Ratings:

A colorless diamond is judged through the grading scale – that shows the presence of colors the stone has. They are as follows:

* D-E-F: Colorless.
* G-H-I-J: Nearly colorless.
* K-L-M: Faintly tinted, usually yellow.
* N-O-P-Q-R: Lightly tinted, usually yellow. Tint can be visible through naked eye.
* S-T-U-V-W-X-Y-Z: Tinted, usually yellow, cloud turns as brownish color since; the tint is easily visible to the naked eye, even when mounted.

Fluorescence: It is one of the factors that affect diamond color. GIA diamond reports and many other lab reports show that all diamonds have certain amount of fluorescence, since diamond changes its color when it gets exposed to ultra violet rays.

For Instance: Diamonds with blue reflection appear whiter or more colorless under UV light and the yellow fluoresce appear more yellow in bright light

Identifying the color of a diamond is easier than expected. The color grading scale simplifies the diamond quality to fit your budget. However, if you don’t want to compromise then choose the diamond that falls in D to F grade and to save some amount you can opt for G to J grade. This way you can select your own diamond as per your budget specification without an expert opinion.

Tolkowsky Ideal Cut Diamond

The ideal cut diamond is the cut that most people desire to have in their piece of jewelry. It was in the year 1919, a well know engineer Marcel Tolkowsky published a book under the title ‘Diamond Design’. The book encapsulates the diamond proportions that form a merely round cut diamond to an ideally proportioned one, that would give maximum brilliance and stand out to an ideal cut diamond. 

Marcel Tolkowsky, a mathematician by profession, applied the fundamental law of physics to calculate a set of proportions that would cause the optical performance of a round brilliant cut diamond. Since, childhood he had got a real life exposure to diamond cutting process because his family were in the diamond business. 

The fundamental of an ideal cut diamond proved to be exceptional and got approved by well know experts from the diamond industry. Tolkowsky was contented as his studies of proportioning the diamond matched to his calculations which were initially used by experts. The experts in the diamond industry were quite happy with his analysis thus eventually making it the famous Ideal cut till date.

In the year 1950, AGS applied Tolkowsky’s model and made a few changes in the symmetry and polish of the diamond to complete their system. In 2006, they came up with a new method which was formed on light performance. Since then, they used quite similar proportions as to Tolkowsky and he became the creator of the modern round brilliant cut which is still rated as one of the best in the diamond industry!
