What part of a gemstone is referred to as the crown?

The crown of a gemstone is defined as the top part of the stone that extends above the girdle, which is the widest part of the cut gem. This section is crucial because it functions as the surface that reflects light, contributing significantly to the stone's brilliance and overall appearance. The crown is designed in a way that maximizes the entry and reflection of light, enhancing the stone's sparkle. Its facets typically include the table, which is the flat top surface, and a series of additional facets that form the crown's shape and help in achieving spectacular light play. Understanding the crown's role is essential for evaluating a gemstone's cut quality, which can greatly influence its visual appeal and value.
