Maximize sparkle and elegance with our gemstone cuts and shapes guide. Learn which cut suits your style best.
BY PHILIP TRENTON, ARTCENTRON
Choosing the right gemstone for jewelry is about more than color and carat weight. The cut and shape of a gemstone determine how it looks, reflects light, and fits into your jewelry design. This gemstone cuts and shapes guide will help you understand the most popular styles, how each performs, and how to choose the perfect stone for your taste.
Understanding the difference between cut and shape gives you the confidence to select a gemstone for rings, pendants, or earrings.
Cut vs. Shape: What’s the Difference?
In this guide, it’s important to know that cut and shape are not the same.
- “Cut” refers to how the gem is faceted and polished to maximize brilliance and sparkle. It affects light performance and the gem’s liveliness.
- Shape is the gem’s overall outline, such as round, oval, or pear.
Both cut and shape influence the beauty and value of the gemstone. A well-cut stone reflects light efficiently, while a pleasing shape complements your style and jewelry design.
Popular Gemstone Cuts and Shapes
1. Round Brilliant Cut
The round brilliant cut is the most popular and classic cut. It features up to 58 facets arranged to reflect light in many directions. This maximizes sparkle, making it a top choice for engagement rings. Its symmetrical outline also hides minor inclusions.
2. Princess Cut
The princess cut is square or slightly rectangular with pointed corners. Its faceting pattern mixes brilliance with geometric lines. This cut often looks larger face-up than its carat weight suggests and is popular in modern rings. Protective settings help prevent chipping at the corners.
3. Oval Cut
The oval shape is an elongated round brilliant cut. It offers the same sparkle as a round cut with a graceful silhouette. Its length can make fingers appear longer and the stone appear larger. A well-cut oval minimizes the “bow-tie” effect.
4. Cushion Cut
The cushion cut has a square or rectangular outline with rounded corners. Its broad facets give a soft, romantic glow. This cut is often chosen for vintage or antique-inspired designs. While less sparkly than some brilliant cuts, its charm lies in its warmth and elegance.
5. Emerald Cut
The emerald cut is a rectangular step cut with long, parallel facets. It emphasizes clarity and color rather than sparkle, producing a hall-of-mirrors effect. This cut is ideal for transparent gemstones like emeralds and sapphires, giving a refined, sophisticated look.
6. Marquise Cut
The marquise cut features an elongated oval with pointed ends. Its shape maximizes face-up surface area, making stones appear larger. It also creates a finger-lengthening illusion when set in rings. Protective prongs at the points are recommended.
7. Pear Cut
Also called the teardrop cut, the pear shape combines a rounded end with a pointed tip. Its graceful silhouette works beautifully in pendants, drop earrings, and rings. Pear cuts also create a slimming effect on fingers.
8. Radiant Cut
The radiant cut blends the brilliance of round cuts with the trimmed corners of emerald cuts. Its many facets produce a lively sparkle while maintaining a geometric, modern appearance. Radiant cuts complement both diamonds and colored gemstones.
9. Asscher Cut
The Asscher cut is a square step-cut known for its vintage Art Deco style. Large facets reflect light in broad flashes rather than tiny sparkles. This cut highlights clarity and symmetry, making it ideal for elegant rings.
