Cut and Shape of Gems

A gem’s shape refers to the face-up outline displayed by the cut of a particular gemstone. In nature, the shape of a gemstone is determined by its natural crystal structure and the conditions under which the crystal developed. To enhance the natural beauty of the crystal and provide suitable shapes for mounting, gem cutters form flat, symmetrical planes, called facets, which catch and reflect light to emphasize preferred colors, sparkle, and brilliance of the finished stone. In addition, gem cutters try to select shapes and cutting styles which allow them to minimize the appearance of undesirable flaws and to get the maximum weight from the rough gem material. The most common shapes include round, oval, square, triangle, pear, marquise, heart, and cushion. With diamonds, shapes other than round are often referred to as fancy cuts.

Cutting Style

Cutting style refers to the way in which a gemstone is cut or faceted. Gemstone cutting is based on science. Each gem material has a known refractive index which allows a gem cutter to determine how light rays will bend as they pass through the stone. Using this information a gemstone can then be precisely shaped to best enhance its natural beauty.

The styles of gem cuts are generally divided into faceted gems (gems with geometrically shaped flat polished faces) and non-faceted gems (those gems that do not have geometrically shaped flat polished faces such as cabochons). The most common and basic cutting styles are as follows:

Cabochon Cut

Antique Jewelry Has a dome-shaped top that is polished but un-faceted. The term comes from a French word signifying a bald pate (caboch, from the Latin cabo, meaning a head). Opaque, asteriated, iridescent, opalescent, or chatoyant stones are usually cut en cabochon. The back of a normal cabochon-cut stone is flat, but it may be hollowed to lighten the color. This is the simplest cut for a stone and is often seen in antique jewelry. Since the cabochon is the simplest style and often made from lower quality material that is unsuitable for faceting, it generally costs less than faceted stones.

Step Cut

Has rows of facets that resemble the steps of a staircase. A step cut gem has sloping, four-sided elongated facets that are cut below the table and run parallel to the stone’s girdle. There are fewer facets in a step cut diamond than in a brilliant cut stone. The baguette, a square-cornered, rectangular stone is an example of a step cut. If step cuts have clipped-off corners, they’re called emerald cuts because emeralds are often cut this way. This protects the corners and provides places where prongs can secure the stone.

Diamond Brilliant

Brilliant Cut

Brilliant Cut Has mostly 3-sided facets which radiate outward from the stone and are positioned so that the light coming through them interplays in such a way to best enhance the stone’s brilliance. Kite- or lozenge-shaped facets may also be present.

The best-known example is the full-cut round brilliant, which has 58 facets. Ovals, pears, marquises, and heart-shapes can also be brilliant-cut. The single cut, which has 17 or 18 facets, is another type of brilliant cut. Square brilliant cut stones are called princess cuts. Triangular brilliant cuts are called trilliants. Gemstone pendants or earrings are occasionally cut as briolettes. These have a tear-drop shape, a circular cross-section, and brilliant-style facets.

Mixed Cut

Mixed cuts include faceting elements from both the brilliant and step cut techniques, either side by side or in different areas of the gemstone. Mixed cuts are popular for colored gemstones.

Fancy cut generally refers any cut which is not a standard cabochon, brilliant cut, or step cut. A very common old-style fancy cut is the rose cut which has brilliant-style facets, a dome-shaped crown, a flat base and a round girdle outline. Rose cut may also be cut with a pavilion. Other common examples of fancy cuts are the checkerboard cut which is step- and brilliant-cut with a large table facet on the crown. Another example is the millennium cut which has a step-cut crown and a pavilion with concave faceting.

Evaluating a Well-Cut Gemstone

Cut quality refers to the proportions and finish of the gemstone. This is a crucial factor because it affects the brilliance and color of gems, but its importance is not always reflected in the price of colored gemstones. Our gemologists have put together a couple of handy tips to help you quickly evaluate a gemstone’s quality.
  1. View your gemstone face up and see whether it exhibits even color distribution all across the stone. Well-cut stones do not display large black areas or any washed out areas that allow you to see right through them. In general, the larger the window, the poorer the cut. Even color distribution is normally a sign of good quality cut.
  2. Examine the entire shape of the gemstone and consider it to its carat weight. If you were to compare two stones with the same face-up size, the one that has a deeper and fatter bottom will weigh considerably more than a well-cut stone with a more shallow bottom. The overly deep stone would potentially cost more, even though it has the same face-up size; however, it may be impractical for mounting and appear overly dark.
