Let's resume with the other two C's and then I will put it all together to explain the relation between the 4 C's and pricing.

Clarity
Clarity is the degree to which a diamond is free of blemishes and inclusions. Blemishes are external - such as scratches, small nicks. Inclusions are within the stone - some other mineral crystal, breaks (feathers), etc. Inclusions have a greater impact on value, beauty, durability and grade of a diamond. G.I.A. classifies diamonds into 11 grades - from IF to I3.

Clarity Chart
IF-FL - Internally Flawless to Flawless. I.F. as it mentions have nothing in them and F.L. have only minor blemishes which can be removed by polishing.
VVS1-VVS2 - Very Very Slightly Included.
VS1-VS2 - Very Slightly Included
SI1-SI2 - Slightly Included. After SI2 inclusions are visible with the naked eye in diamonds of larger size.
I1-I3 - Included. This category affects the durability and beauty of the stone drastically, no matter what the size.

Well Cut, deep Cut and Shallow Cut Terminology about Cut.

Cut
Cut is the human touch to a diamond's beauty. It is one of the most important of the 4 Cs. If a diamond is cut properly, then it can both enhance color and hide inclusions. Cut also determines the amount of light returned to the eye after it has entered the diamond. If a diamond is cut too deep (called 'Nailhead') or too shallow (called 'Fish Eye') then light leaks out of the diamond pavilion. In other words a diamond will not have a good dispersion if it is not cut well. That could be disastrous. Cut also includes minute details that make up the full geometry of the diamond such as girdle thickness, facet arrangement, crown angle, table size, etc. It is not one thing but a whole collective that makes up Cut. It also includes the various diamond shapes.

Different types of diamond shapes - Heart, Princess, Baguette and Oval Different types of diamond shapes - Round, Marquise, Pear and Emerald

In the next section, I will explain the relationship between the 4 Cs that make up the 5th C - Cost.
