The 4 C’s
No matter the gemological institution, no two diamonds are the same, and there are still discrepancies that are up for interpretation. The four Cs are what the price of your diamond is based on, not the value; you attribute that yourself by the life events, memories, and loved ones you connect to it. At the end of the day, a diamond’s worth is what you deem it. The four Cs are simply there to guide you to your perfect stone with the criteria:
– Carat: The unit of measuring a diamond’s weight. One carat is equal to 0.2 grams, about the same weight as a paperclip. A carat is divisible into one hundred points; for example, a 40-point diamond weighs 0.40 carats.
– Color: Diamonds are also priced on their color, or rather the lack thereof. The less color a diamond has, the greater their value, with the exception of fancy-color diamonds such as blues or pinks. They are judged by the Gemological Institute of America’s D-Z Color Grading Scale, with D being colorless and Z being light yellow or brown. Each letter grade is clearly defined by comparing new stones to ones with a predetermined letter grade in controlled lighting.
– Clarity: The clarity of a diamond is affected by two different types of visual obscurers: inclusions (internal) and blemishes (external). They are graded on a scale with eleven grades, from flawless to obvious inclusions. They are judged on how visible they will be under a 10x magnification.
– Cut: The cut of a diamond determines a diamond’s fire, sparkle, and brilliance and is graded on a scale from Excellent to Poor. It refers to the stone’s proportions, symmetry, and polish. While the most standard cut in the industry is a round brilliant, there are other fancy cuts such as pear, emerald, oval, and many others.
