The 4 C’s Diamonds
While we often mistake a diamond’s cut as its shape (pear, oval, round, heart or marquise being common diamond shapes), the cut gives it the unique ability to interact with light. The workmanship involved in cutting loose diamonds decides how beautiful and valuable they will be. While a precisely cut diamond will appear more luminous, a poorly cut diamond can appear dark and lackluster. Simply put, a diamond’s cut unleashes its light. To understand how well the light will reflect back to the viewer, you need to look at the diamond from the pavilion angle. If it’s too shallow, then it will cause less light to return. If it’s too deep, again it will cause a loss of light. But an ideal cut diamond will allow light to pass within it and reflect it back to the viewer.
CUT GRADES OF DIAMONDS:
Exhibits optimal fire and brilliance as all the light that enters is reflected by the diamond.
Exhibits an asymmetrical pattern of light and dark spots.
Does not exhibit as much light because the fire and brilliance is not at par.
Does not retain any light that enters the diamonds.
Appears dull even without magnification.
While most diamonds look white, there are in fact many subtle shades. The closer the diamond is to being colorless, the more valuable it is. Pure diamonds, which are the rarest and most valuable, are perfectly transparent and colorless.
Globally, diamonds are graded on a color scale from D-Z and segregated into five categories:
COLOR Grades of diamonds:
Diamonds in this range are the rarest ones. These are best mounted in platinum or white gold as yellow gold will take away rom its luminosity.
These diamonds exhibit almost no color face up and are suitable for a platinum or white gold setting. These are great value diamonds.
Diamonds in this range show a slight hint of color when it’s placed face up, and are more easily detected by the naked eye. Those who prefer a warmer look of faint color diamonds. They are best set in yellow gold jewelry.
Very Light Yellow
Diamonds in this range have an easily detectable hue of yellow, and are more affordable than higher grades.
These diamonds have a easily noticeable yellow or brown hue.Beyond this grading are ‘fancy diamonds’ which have a deeper color. Perfectly yellow or brown diamonds are considered fancy colored diamonds and are usually also desirable.
All diamonds contain small imperfections inside them (called inclusions) or on the surface (called blemishes). Clarity refers to the degree of imperfections present in the diamond. The ones with more imperfections have lesser brilliance and vice versa.
Diamonds are graded for clarity using a 11 point scale created by the GIA which considers the number, size, color, reflectivity, and position of every flaw visible under 10x magnification.
Inclusions are obvious under 10x manification and may affect transparency and briliance. They may be visible to the naked eye in larger stones.
Slightly Included SI1/SI2
Inclusions are notciable to a skilled grader under 10x manigcation. Known as the best value diamonds. These may be visible to the keen eye withouth a magnification in large stones.
Very Slighty Included VS1/VS2
Inclusions are minor and range from difficult to somewhat easy for a skilled grader to see under 10x magnication. These inclusions cannot be seen without a 10x magnification.
Very Very Slightly Included VVS1/VVS2
Inclusions are difficult for a skilled grader to see under 10x magnification. Diamonds have miniscule inclusions not visible with the naked eye.
Iternally Flawless IF
No inclusions only blemishes are visible to a skilled grader using a 10x magnification. It is an internally clean stone.
No inclusions or blemishes are visible to a skilled grader using a 10x magnification. These are extremely rare and less than 1% of diamonds are FL.
Carat is a term that refers to the weight of a diamond. In the United States, most of the diamonds used in the jewelry are 1 carat or lesser. The carat weight impacts the cost of the jewelry. When investing in diamond engagement ring, 1 to 2 carats are the preferable as they are of higher quality and give the desirable brilliance.
Diamonds come in many different shapes. Each diamond possesses its own unique features thats set it apart from others. Each of these may cause the diamond to reflect light in a different ways and change how you view it. The shape is a preference which best fits you.
