There is much more to a diamond than just the four C’s, but let’s start there…
The cut of a diamond varies greatly depending on the crucial decisions a cutter makes when fashioning a diamond.
Other important factors of the cut include:
All of these elements will contribute to the overall brilliance, fire and scintillation a diamond will have.
Clarity is a diamond’s relative freedom of any clarity characteristics often referred to as inclusions and/or blemishes.
Inclusions are imperfections that are enclosed inside a diamond or depending on the type of inclusion, they can extend into a diamond from its surface. Inclusions can become a part of a diamond during the formation period. They can either be visible with the naked eye or require magnification. The harder it is to detect an inclusion or how few inclusions a diamond has, will greatly impact its value.
Blemishes are confined to the surface of the diamond such as polish lines and often have less impact on a diamonds value than inclusions do.
How diamond graders determine diamonds clarity?
There are five key factors that determine a clarity grade. Most of them relate to how readily you can see a clarity characteristic/inclusion.
A diamonds colour grade is based on how noticeable the colour is, also referred to its depth of colour. Diamonds that range from colourless to light yellow and light brown fall within the normal colour range. The Gemological Institute of America or GIA created the D-Z scale where each letter represents a diamonds grade, D is the most valuable where as Z the least. We invite you to view the diagrams and charts below for further explanation.
The weight of diamonds as well as most other gemstones is expressed in metric carats. One metric carat equals 0.200grams; a carat is divided into 100 equal parts called points.
1.00 = 100 equal parts = one full carat
0.65 = 65 points (under one full carat)
If all other factors are equal, the more a diamond weighs, the larger it typically is, and the more valuable it will be.
Please note: the weight of a diamond does always translate to the visual size of a diamond. If a diamond is not cut properly the diameter of the stone can vary greatly, often making it appear larger or smaller and impacting the refraction.
What are some other discerning factors that can greatly affect a diamonds appearance and value?
Fluorescence is when a diamond emits light or glows when it is exposed to ultraviolet radiation (UV light). About 35 percent of gem quality diamonds emit some degree of fluorescence and is most noticeable under a UV lamp, however, can be visible in normal daylight. Diamonds with strong fluorescence can have an oily or cloudy-like appearance even under normal light.
Please take the time to view the two images of diamonds shown below. These two diamonds are the identical cut, clarity, colour and carat size. Notice how the one on the right is quite noticeably cloudy or milky in appearance, even though they are both graded as a VS1 clarity, E colour, and Excellent cut grade.
Graining or grain lines are visible, shadow-like lines in a diamond caused by irregularities in the crystal structure. Graining occurs when environmental conditions change during the crystal growth process. There are several types of graining that can appear in a diamond.
Other common irregularities that can affect a diamonds appearance:
There are a myriad of factors that can compromise the overall appearance of a diamond, especially for those with a discerning eye. When purchasing a diamond at Maxime’s you trust us to the best job for you finding your perfect diamond.
