Gemstone Cuts and Shapes | Facets and Cabochons

Have you ever wondered why gemstones come in so many different shapes and cuts? From the sparkling brilliance of a diamond to the smooth, polished surface of an opal, the art of shaping gemstones is truly fascinating. 

Gemstone cuts and shapes not only enhance the beauty of the stone but also affect its value and how it interacts with light. In this article, we will come to know about facets and cabochons, the two primary styles of gemstone cutting. By understanding these techniques, you’ll gain a greater appreciation for the craftsmanship that goes into every precious gem.

What are Facets?

Facets are small, flat surfaces cut into a gemstone to enhance its brilliance and sparkle. When light enters a faceted gemstone, it is reflected off these surfaces, creating the dazzling effect we often associate with precious stones. 

Faceted cuts are commonly used for transparent stones like diamonds, sapphires, and emeralds. The most popular faceted cut is the round brilliant cut, which maximizes the stone’s sparkle by using 58 facets.

Other well-known faceted cuts include the princess cut, emerald cut, and oval cut. Each cut has its unique pattern of facets that can highlight different aspects of the gemstone, such as its color or clarity.

Understanding Cabochons

Cabochons are gemstones that have been shaped and polished instead of faceted. They have a smooth, rounded surface and are often used for opaque or translucent stones like opals, turquoise, and moonstones.

The cabochon cut is one of the oldest gemstone cuts, dating back thousands of years. This cut is particularly popular for stones with unique patterns or inclusions, as the smooth surface allows these features to be seen clearly.

Cabochons are typically cut into simple shapes like circles and ovals, but they can also be found in more elaborate forms, depending on the stone’s natural characteristics.

Popular Non Faceted Shapes

Cabochons come in a variety of shapes, with the most common being round and oval. These shapes are favoured because they complement the natural form of many gemstones, minimizing waste during the cutting process.

Other popular cabochon shapes include teardrop, marquise, and heart. Each shape can enhance the gemstone’s inherent beauty, showcasing its unique patterns and colors.

For example, a teardrop cabochon might highlight the flowing patterns in an opal, while a heart-shaped cabochon could emphasize the rich color of a ruby.

How Cuts Affect Value

The cut of a gemstone significantly impacts its value. A well-cut gemstone will reflect light beautifully, enhancing its color and brilliance. For faceted stones, the quality of the cut can make a difference in how much the gemstone sparkles.

In contrast, the appeal of a cabochon lies in its smooth surface and the way it showcases the stone’s natural features. Gemstones with high-quality cuts, whether faceted or cabochon, are generally more valuable because they display the stone’s best attributes.

Therefore, the precision and artistry involved in cutting a gemstone play a crucial role in determining its worth.
