The Winning ‘C’: The Importance of the Diamond Cut

Most people who start searching or showing interest in buying a diamond encounter many terms that are specific to the world of diamonds. The term that appears in almost every article or information search on diamonds is “The 4 C’s,” or in detail:

• Carat: The weight of the diamond measured in carats (1 carat = 0.2 grams, 100 points = 1 carat).
• Color: The color of the diamond, ranging on a scale from D (the highest color, completely colorless) to Z (the lowest color, almost yellow/brown).
• Clarity: The cleanliness of the diamond, ranging on a scale from FL (flawless, without any inclusions) to I3 (Full of significant inclusions visible to the naked eye, impacting the diamond’s overall appearance)
• Cut: The quality of the diamond cut, including proportions between polishing surfaces, angles, pavilion depth, and table size – all these factors collectively affect the quality of light entering the diamond and reflecting back, creating the effects of brilliance and the different colors perceived by the human eye when looking at the diamond. It ranges from Excellent cut (perfect proportions) to Poor cut (very low proportions quality).

All four factors together influence the quality and sparkle of the diamond, and of course, its price in the market.

What not everyone knows is how crucial the last factor on the list (Cut) is for achieving the desired effect from a diamond-set piece of jewelry: dazzling with a full spectrum of colors, full of “fire,” and captivating the eyes of its surroundings.

And behold, this is what truly matters: how much the diamond you bought for your loved one, or treat yourself with, sparkles and shines with life! It doesn’t really matter now whether the clarity is SI2 or VVS1 when the cut quality of the diamond is Poor. For example, a diamond with a color grade of K, clarity of SI2, and an excellent cut will sparkle and impress much more than a diamond with a color grade of D, clarity of VS2, but with a poor cut.
