Diamonds have been a very sought-after since ancient times. Some historians and anthropologists have discovered diamond used as far as 30 thousand years B.C. Diamonds have been used as decorative items, as jewelry, and as clothing accessories too. These gifts from Mother Nature are the result of primordial geological events, which modified rocks and minerals to the point of creating beautiful pieces that are considered beautiful by many societies.

Diamonds are a commodity that has been used in commerce so much that there are many groups dedicated to grading their qualities and thus the attractiveness of diamonds throughout the world. The desirability of a diamond can very well define its market price.

These precious gemstones have been appreciated by humanity for a great number of reasons Humankind have set a plethora of standards to define what makes a diamond beautiful or more special than the others. There are several samples you can see in Diamonds-usa to understand what we are talking about. A diamond may present some rare or very infrequent characteristics that make it special. These characteristics can be graded taking into account the “four C’s” of diamond quality, such as Cut, Carat, Clarity, and Color.

Let’s dive right into the things that define the types of diamond out there.


It is considered an art and a science. The diamond is cut from its rough form found in nature to the shape that will show its brilliance and quality. Many imperfections can be avoided when working with professionals that will make a perfect cut.



Carats reflect the size of the diamond. The bigger it is, the more it weighs, and the more expensive it will be. This feature has a point value that takes 100 for 1 carat. This is done because most diamonds in the market are not bigger than one carat.


The clarity of a diamond, as defined by the GIA system has eleven grades and six categories.

Flawless: a diamond that is flawless has no blemishes and visible inclusions using a 10x magnifier glass.

Internally flawless: a diamond that has no visible inclusions using 10x magnification, it only has small blemishes on its surface.

Very, Very Slightly included: it is a diamond with miniscule inclusions that are challenging to see even for a skilled expert using a 10x magnifier glass. This category has two subdivisions:  VVS1 being of a higher clarity than VVS2.

Very Slightly Included has minor inclusions that may be difficult or somewhat easy for a trained using 10x magnification. VS1 have more clarity than VS2, and its inclusions are most of the time invisible without the magnifier glass, Some VS2 inclusions may be visible.

Slightly Included: a diamond with inclusions that can be very easy for a trained person with a 10x magnifier glass. SI1 SI2. The inclusions may be visible to the naked eye.

Included: are diamonds with obvious inclusions that are visible to a person that has been trained using 10x magnifier glass, or without it. These can endanger the durability of the stone and can affect how much it shines. I1 are of a higher clarity than I2, which is clearer than I3.


The most appreciated characteristic in diamonds is the absolute absence of color. Often called white diamonds, these types of diamonds mostly present a very light shade of yellow. It is very rare to find a diamond that is completely transparent. Most diamonds that appear perfectly transparent, after closely inspected by an expert, can present very light tones of yellow and even brown.

The presence of color in a diamond is due to impurities in the nature of its mineral composition. Yellow coloration is due to the presence of nitrogen, and its intensity is known to be due to its concentration on the diamond.

The GIA (Gemological Institute of America) classifies low yellow and brown saturation as a normal range diamond. There is a scale for this. It goes from the letter ‘D’ (colorless) to the letter ‘Z’ (lightly yellow).

If a colored diamond has a very special hue and intensity in its color, it may be considered very special. It is rare to find diamonds like this, but intensely colored diamonds are present and in all of the colors of the rainbow.
