Diamonds: Understanding the 4C's of a diamond. Diamond Clarity

Size Matters - So does Cut, Color & Clarity
Part 3

Clarity 
The clarity of a diamond refers to the number and location of imperfections and blemishes a diamond has.

Every diamond is unique. None is absolutely perfect under 10× magnification, though some come close. Known as Flawless diamonds, these are exceptionally rare. 
                                                                    -GIA

We have covered how cut and color affect a diamond's brilliance.  An imperfection can also interfere with the reflection of light within the stone. Imperfections hinder the brilliance of the diamond by actually stopping the light.


What is an inclusion? Inclusions are clouds, feathers, included crystals or minerals, knots, cavities, cleavage, bearding and internal graining.


What is a blemish?
 Blemishes are polish lines, grain boundaries, naturals, scratches, nicks, pits and chips.


The size, number, position, nature and color of the blemishes and imperfections determine the clarity grade of the diamond. If a diamond has one big imperfection will get a lower grade than a diamond that has one small imperfection. Just as if a diamond has several imperfection versus only one. The position of an imperfection is important as well. An imperfection in the center of the table will be more visible than one off to the side, as the inclusions can be masked from the brilliance.


We recommend examining any stone you are considering for purchase just as the GIA does, under a 10x magnification using a jeweler’s loupe. Even the experts cannot evaluate a diamond without this simple tool. At Jester Jewelers we will always provide you with a loupe when considering a stone for purchase.
