Quick Summary

Faceting is a gem-cutting technique that involves creating flat, polished surfaces on a gemstone. These surfaces, called facets, are typically arranged in geometric patterns to enhance the stone's brilliance and beauty through the refraction and reflection of light.12

A faceted stone has distinct parts: the crown (upper portion) and the pavilion (base), separated by the girdle (widest part). Common faceting styles include the brilliant cut, known for its 58 facets designed for maximum sparkle, and the step cut, which features rows of rectangular facets often used for emeralds and amethysts. The rose cut, with its domed, faceted top and flat base, was historically popular for diamonds. The precise angles and placement of facets are crucial for maximizing a gem's visual appeal.13425
