Gemstone cutting is an ancient art that has evolved significantly over the centuries. The way a gemstone is cut can dramatically affect its beauty, brilliance, and value. Let's explore some of the most popular gemstone cuts and shapes, along with their history and characteristics.
Historical Cuts
Cabochon Cut
The cabochon is one of the oldest gemstone cuts, dating back thousands of years. It features a rounded, polished top with a flat bottom.
Cabochons are ideal for showcasing gems with special optical effects like asterism (star effect) or chatoyancy (cat's eye effect). This cut remains popular for opaque or translucent stones like opal, moonstone, and star sapphire.
Faceted Cuts
Brilliant Cut
The brilliant cut was developed in the 17th century to maximize a diamond's fire and brilliance. It features numerous facets arranged in a specific pattern to reflect light.
While originally designed for diamonds, the brilliant cut is now used for many gemstone varieties. Popular brilliant cut shapes include round, oval, marquise, pear, and heart.
Step Cut
The step cut, featuring rectangular facets arranged in parallel rows, emerged in the early 20th century. The most famous step cut is the emerald cut.
Step cuts emphasize a gem's clarity and color rather than sparkle. They work well for emeralds, aquamarines, and other transparent colored stones.
Mixed Cut
Mixed cuts combine elements of brilliant and step cuts. A popular example is the princess cut, developed in the 1960s.
Mixed cuts aim to balance brilliance with color retention, making them versatile for many gem types.
