Cut • Color • Clarity • Carat Weight
Among the 4Cs, the cut of a diamond has the most significant impact on its beauty. When assessing the cut’s quality, we look at how skillfully the diamond is fashioned. The more precise the cut, the more enchanting the diamond appears to the naked eye.
Gem-quality diamonds exhibit a diverse array of hues, spanning from colorless to light yellow or light brown. Among these, colorless diamonds stand out as the rarest and most coveted. In contrast, diamonds with natural hues such as blue, red, or pink fall into the category known as “fancy.” The grading system for these fancy-colored diamonds differs from that of white colorless diamonds, reflecting the unique and captivating spectrum of colors found in these exceptional gems.
Diamonds can possess internal characteristics referred to as inclusions or external characteristics known as blemishes. While diamonds without inclusions or blemishes are considered rare, it’s important to note that most of these characteristics are only visible under magnification. The presence and visibility of inclusions and blemishes are crucial factors in diamond grading, influencing both the diamond’s value and overall appearance.
The carat is a unit measuring the physical weight of a diamond in metric carats, where one carat is equivalent to 1/5 of a gram and is further divided into 100 points. Carat weight serves as the most objective grade among the 4Cs, providing a straightforward measure that directly influences a diamond’s perceived value and rarity.
