THE 4Cs
The 4Cs of diamonds represent the universally recognised criteria used to assess and evaluate the quality and value of a diamond. These criteria include Cut, Colour, Clarity, and Carat Weight.
CUT
The cut of a diamond refers to the precision with which it has been shaped. It significantly impacts the diamond's brilliance and overall appearance. A perfect cut enhances the diamond's natural beauty and maximises its potential to sparkle, making it a key factor in determining its overall value.
At WILLIAM ÉDOUARD, we source "Excellent" to "Very Good" grades of cut.
COLOUR
Diamonds come in various colours, ranging from colourless to light yellow or brown. The colour scale for diamonds begins with the letter D, representing colourless, and ranges all the way to Z, representing light yellow or brown tones. The less colour a diamond has, the more valuable and rare it is considered.
At WILLIAM ÉDOUARD, we source colourless to near-colourless grades of "D" to "H" colour.
CLARITY
Clarity refers to the presence of internal characteristics, known as inclusions, and external features, known as blemishes, within a diamond. These characteristics are a result of the natural formation process of the diamond. The clarity grade assesses the number, size, relief, nature, and position of these imperfections.
At WILLIAM ÉDOUARD, we source diamonds between a grade of IF (internally flawless) to VS (very slightly included) and SI (slightly included) clarity.
CARAT WEIGHT
Carat weight is a measurement of a diamond's weight. While carat weight directly influences the price of the diamond, it is essential to remember that the value of a diamond is also determined by the above factors, which play an equally significant role in evaluating a diamond's overall worth and visual appeal.
At WILLIAM ÉDOUARD, we can source diamonds in any carat weight you like.
SUSTAINABILTIY
At WILLIAM ÉDOUARD, all our diamonds are conflict-free and ethically sourced in compliance with the Kimberley Process, with certifications provided by the Gemological Institute of America (GIA), the preeminent global expert on diamonds and diamond grading.
