Key Takeaways

  • Popular cuts for engagement rings include round brilliant, princess, cushion, and emerald
  • Cut grade, cutting style, and proportions are factors that affect a diamond's beauty and value

Fundamentals of Diamond Cuts

Diamond Shapes

Diamond shapes refer to the overall silhouette of the stone. There are various shapes available, with the round brilliant cut being one of the most popular. This Cyan Blue VVS Round Brilliant Cut Loose Moissanite Diamond is a good example of a round diamond that shows off its beauty and brilliance. Other shapes include oval, pear, princess, cushion, emerald, and more. Choosing the right shape for an engagement ring depends on personal preferences and the desired style of the ring.

Diamond Facets

Facets are the flat, polished surfaces that make up the external structure of a diamond. They are responsible for reflecting and refracting light, which contributes to the stone's overall brilliance. The number of facets in a diamond depends on its cut and shape. For instance, round brilliant cuts typically have 58 facets, including the table and cutlet. Colorless Moissanite Loose Stones are available in a variety of cuts with different facet patterns to suit various preferences and styles.


Brilliance refers to the amount of white light that a diamond reflects. It is determined by the cut and proportion of the stone, with the ideal cut delivering maximum light reflection. When a diamond is well-cut, it exhibits a high degree of brilliance, making it look brighter and more attractive.


Fire, also known as dispersion, refers to the ability of a diamond to separate white light into its spectral colors, creating a rainbow-like effect. Diamonds with a good cut and a high refractive index will exhibit more fire. This captivating effect adds to the overall attractiveness and appeal of a diamond engagement ring.


Scintillation is the sparkle that occurs when a diamond is moved or when the observer changes their viewing angle. This effect is a combination of white light (brilliance) and colored light (fire) reflections, along with the dark and light pattern contrast caused by the diamond's facets. A well-cut diamond will have an even and balanced display of scintillation, enhancing its beauty and making it an excellent choice for engagement rings.

Popular Cuts for Engagement Rings

When it comes to choosing a diamond engagement ring, the cut of the diamond plays a crucial role in determining the overall appearance and brilliance of the ring. This section will discuss three popular cuts: Round Brilliant Cut, Princess Cut, and Cushion Cut, along with their unique features and appeal.

Factors Affecting Diamond Beauty and Value


The color of a diamond has a significant impact on its beauty and value. Diamonds range from colorless to light yellow or brown, and their color is graded on a scale from D (colorless) to Z (light yellow or brown). Colorless diamonds are considered the most valuable, as their lack of color allows light to pass through them without distortion, resulting in greater brilliance and fire. As the color becomes more noticeable, the diamond's value decreases. However, some individuals may find a slightly warmer-colored diamond to be preferable, depending on personal taste.


Clarity refers to the presence of natural imperfections known as inclusions within a diamond. Fewer inclusions mean a higher clarity grade and increased value. Clarity is graded on a scale that ranges from Flawless (no inclusions visible under 10x magnification) to Included (inclusions easily visible to the naked eye). While clarity can significantly impact a diamond's beauty, particularly in larger stones, many inclusions are not visible without magnification and may not greatly affect the diamond's overall appearance. In such cases, a lower clarity grade may be more affordable without sacrificing much in the way of aesthetics.

Carat Weight

Carat weight is a measure of a diamond's size and is another crucial factor affecting both beauty and value. As carat weight increases, so does the value of the diamond, generally at an exponential rate. This is because larger diamonds are rarer and therefore more valuable. However, carat weight alone is not enough to determine a diamond's beauty. A well-cut diamond of smaller carat weight may appear more brilliant and fiery than a poorly cut diamond of greater carat weight.

When choosing a diamond for an engagement ring, it's essential to consider the balance between color, clarity, and carat weight, understanding that trade-offs may need to be made to fit within a given budget. By prioritizing the factors that matter most to the individual and understanding how each element contributes to the diamond's overall beauty and value, one can select the perfect stone to symbolize their love and commitment.

Cut Grades and Cutting Styles

When considering diamonds for engagement rings, cut grades and cutting styles play a significant role in determining the overall appearance and value of the gemstone. Cut grades refer to the quality of a diamond's proportions and symmetry, while cutting styles are the shapes and faceting patterns the diamond receives during the polishing process. In this section, we will explore two popular cutting styles: Step Cut and Brilliant Cut.

Step Cut

Step Cut is a cutting style characterized by its straight, parallel facets arranged in a step-like pattern. This design often features a rectangular or square shape, such as the famous emerald and Asscher cuts. The step cut accentuates a diamond's clarity and luster, creating a mirror-like reflection and allowing light to travel smoothly through the stone.

There are various cut grades for step cut diamonds, ranging from poor to excellent. These grades take into account the precision of the facet alignment, the overall symmetry, and the proportions of the diamond. It's essential to choose a high-grade step cut diamond to ensure the best balance of brilliance and elegance.

Brilliant Cut

On the other hand, the Brilliant Cut is designed to maximize a diamond's sparkle and fire by using an optimal arrangement of triangular and kite-shaped facets. The most common example of a brilliant cut diamond is the round brilliant, which features 58 facets and is known for its exceptional light performance.

Brilliant cut diamonds also come in various cut grades, determined by evaluating factors such as the proportions, symmetry, and polish of the stone. When selecting a brilliant cut diamond, it's crucial to consider the cut grade, as it has a significant impact on the diamond's overall appearance and value.

Different shapes like oval, pear, and marquise can also exhibit brilliant cut faceting patterns, providing a wide range of options for those seeking the perfect engagement ring diamond. The choice between a step cut and a brilliant cut ultimately depends on personal preference, as each offers its unique characteristics and appeal.

Choosing the Ideal Cut for an Engagement Ring

When selecting a diamond engagement ring, the cut of the diamond plays a crucial role in determining its overall appearance and brilliance. The ideal cut should maximize the diamond's symmetry and light performance, ensuring that it reflects the most light possible.

One popular option for achieving maximum brilliance and fire is the round brilliant cut. This cut features 58 facets, and its proportions are calculated to provide the best balance between light reflection and dispersion.

Another cut to consider is the princess cut, which is a square shape with sharp corners. This cut also prioritizes symmetry and light performance and is quite popular due to its modern and elegant appearance.

If you're looking for something more unique, consider fancy-shaped cuts like the oval, marquise, or pear. These cuts can create a stunning and distinctive look while still offering great brilliance. Remember, when selecting a fancy-shaped diamond, it's essential to pay attention to the quality of the cut to ensure the best light performance.

Finally, keep in mind that personal preferences also play a role in choosing the ideal cut for an engagement ring. While some may prefer a cut that prioritizes brilliance, others may be more drawn to a cut with a more interesting shape.

When searching for the perfect diamond engagement ring, it's essential to consider both the cut and the overall design of the ring. Take the time to explore different cuts and styles to find the one that best suits your tastes and reflects your love story.
