Diamond Story 4 – Unique Characteristics for Every Gem

Just as every person has a unique fingerprint, each diamond possesses its own distinctive characteristics. The most globally recognized standard for evaluating diamond quality is the 4Cs: Carat, Clarity, Color, and Cut. These elements play a crucial role in determining the value of a diamond.

Carat (Weight)

The Carat weight of a diamond is measured in units called Carats. One Carat equals 0.2 grams, originally derived from the Carob tree seeds used for weighing gemstones. A 1 Carat diamond typically has a diameter of about 6.5mm, while a 4 Carat diamond has a diameter close to 10mm. Carat weight can vary depending on the diamond shape, such as Round Brilliant, Princess, Pear, Oval, Cushion, Marquise, Emerald, Radiant, or Heart, and does not always reflect the actual size. Cutting proportions and depth impact how a diamond appears, even at the same Carat weight.

Cut (Shape and Polish)

The Cut of a diamond refers to how the stone is shaped and polished, playing a significant role in its brilliance and sparkle. Historically, diamonds were cut to maximize their beauty, and modern technology has refined these processes. Today, ideal cuts, like the Round Brilliant Cut, are mathematically calculated for optimal proportions, polish, and symmetry.

A well-cut diamond reflects light internally and externally, creating the best brilliance. A “heart and arrow” effect indicates the highest level of precision. Diamond grading is based on these aspects, with the top grade being ‘Excellent.’ The highest quality diamond, known as a ‘3EX’ (Triple Excellent) cut, demonstrates exceptional craftsmanship and is one of the most sought-after cuts in the world.
