Welcome to the fascinating world of diamonds! For many people, the first shape that comes to mind when they think of a diamond is the round-cut diamond, with its timeless beauty and extraordinary brilliance. The most preferred and popular diamond cut in the world, the round-cut is practically the queen of the diamond world. So, what makes it so special? In this comprehensive guide, you'll find everything you need to know about round-cut diamonds.
Why is the Round Cut So Popular?

The biggest secret of round-cut diamonds lies in the way they reflect light. Meticulously shaped with 58 distinct facets, this cut captures incoming light to its fullest extent and disperses it like a prism, creating a unique brilliance and sparkle. Let's take a closer look at the characteristics that distinguish the round cut from others:
-
Maximum Brilliance: The round cut offers the highest brilliance and scintillation performance. Its proportions are optically perfected to maximize a diamond's potential.
-
Timeless and Classic Beauty: Round diamonds are a timeless, always elegant and sophisticated choice. They complement any jewelry design perfectly, whether it's a ring, necklace, or earrings.
-
Versatility: Round-cut diamonds look stunning in a variety of setting styles, including solitaire, three-stone, or halo. This flexibility makes it easy to find a gem that matches your personal taste and style.
-
Higher Perception of Color and Clarity: The intense brilliance of the round cut is more effective at concealing small inclusions and yellowish tones within the diamond than other cuts. This allows you to choose a diamond at a more affordable price compared to other cuts of the same quality.
Factors Determining Quality in Round Cut Diamonds: The 4C Rule
The quality of a diamond is determined by the well-known 4C rule : Cut , Color , Clarity, and Carat . For round cuts, the following points should be taken into account:
-
Cut: This is the most important factor determining the quality of a round cut. The quality of the cut directly affects the brilliance of a diamond. It is graded as Excellent, Very Good, or Good . To ensure a diamond's brilliance, we strongly recommend choosing a diamond with an Excellent or Very Good cut grade.
-
Color: This indicates how colorless the diamond is. It is graded from D (colorless) to Z (pale yellow). The brilliance of a round cut can mask the yellowness of lower color grades, so colors like G or H often offer a great balance.
-
Clarity: This indicates the amount of natural flaws (inclusions) inside a diamond and the amount of blemishes on its outer surface. It is graded from FL (Flawless) to I3 (Flawed) . Thanks to its brilliant cut, inclusions are barely visible even with clarity grades like SI1 or SI2 , making it a budget-friendly option.
-
Carat: This refers to the weight of a diamond, and therefore its size. Round cut diamonds can appear optically larger than other cuts of the same carat because their top surface area is larger.
