A guide to diamond and gemstone shapes; the art of cutting in the service of beauty
Every cut has a story. In this article, we explore the elegance and unique characteristics of various gemstone shapes to help you find a piece of jewelry that reflects your personal style.
When choosing a piece of jewelry, many focus solely on the 4Cs (Carat, Color, Clarity, and Cut). However, the shape of the gemstone is what defines the "soul" and character of your piece. Your choice of shape not only influences the overall design style but also determines how the stone interacts with light and how it complements your hand. Whether you’re looking for timeless brilliance or a bold, modern statement, understanding the different cuts is the first step toward finding your perfect piece at REI Design.
A Guide to Popular Gemstone Shapes
Round Brilliant: The gold standard of brilliance. With 57 or 58 facets, this classic cut is designed to maximize light reflection. It’s the ultimate choice for those who value timeless elegance and unmatched sparkle.

Princess Cut: Sleek, modern, and geometrically stunning. The princess cut offers a contemporary look with plenty of fire, making it perfect for those who want the brilliance of a round cut in a modern square or rectangular silhouette.

Emerald Cut: Defined by its long, linear facets, the emerald cut exudes sophistication and a "vintage" elegance. It is an "understated luxury" choice—less about intense fire and more about flashes of light and deep clarity.

Oval Cut: A rising favorite for its ability to elongate the finger. The oval cut offers a large surface area, making the stone appear larger than a round stone of the same carat weight. It is both elegant and versatile.

Pear Cut: Often called the "teardrop," this shape is a sophisticated blend of the round and marquise cuts. It is an artistic choice, perfect for those who want something unique and flattering to the hand.

Cushion Cut: Combining a square shape with rounded corners, the cushion cut (or "pillow cut") has a romantic, antique feel. It is known for its incredible soft glow and is perfect for vintage-inspired settings.

Marquise Cut
The Marquise cut, also known as the "navette" (little boat) shape, is characterized by its elongated oval shape with pointed ends. Historically inspired by the smile of the Marquise de Pompadour, this cut is designed to maximize carat weight, often appearing larger than other shapes of the same weight. Its elongated silhouette is exceptionally flattering as it creates the illusion of long, slender fingers. It is the perfect choice for those who love vintage glamour, sophistication, and a bold, unique aesthetic.

3. How to Choose the Best Shape for You
For Maximum Sparkle: Choose the Round Brilliant; it is scientifically designed to return the most light to your eyes.
For Elongating Your Fingers: Opt for Oval, Marquise, or Pear shapes. Their elongated profiles create an illusion of length and grace.
For a Modern, Architectural Look: The Princess or Emerald cuts provide clean lines and a bold, sophisticated structure.
For "Carat Weight" Perception: Oval and Emerald cuts tend to have a larger surface area on top, making them look larger than other shapes of the same weight.
4. Conclusion & Call to Action
Choosing the right gemstone shape is a personal journey, and there’s no "wrong" choice—only the one that speaks to your unique style.
