The design of the faceting on the surface
of a gemstone is the cut. Cut is important to its oveall appearance, greater precision produce greater live and sparkle. The best score and scale in Cut is combination of perfect gem cut, a clean Polish surface free of surface fissures and an excellent faceted Shape.
THE CUT OF THE EMERALDS
A washed-out area in the
center of the emerald is the result of a cut that is too deep or too shallow. In all cases, a well-cut emerald is symmetrical and reflects light evenly across the surface.
In an emerald with more saturated color, the best cut may be more shallow than average, permitting more light to penetrate the gemstone, while in a less saturated gemstone, the color may benefit from a deeper cut.
AGS Cut Grading Scale
is typically determined by rough material. In colored gemstones, there are many different variations on the basic
shapes of ovals, (i.e. cushion, antique and barrel) emerald cut, (i.e. baguette, princess cut, cut corners), among many others.
Emeralds have a table, crown, girdle, pavilion, and culet. Emeralds are frequently cut in a rectangular step cut - a cut used on emeralds so often it's usually referred to as an "emerald cut." The clipped-off corners protect the stone from breakage and provide places where prongs can grip securely.

The brilliance of a stone refers only to faceted gemstones. When a gemstone is properly cut and the material is translucent and crystalline, the play of light and reflection emanating from the gem is commonly referred to as
brilliance. Collectors enjoy seeing their gem's vibrant sparkle under a variety of lighting conditions
Polish describes how smoothly the facets of a emerald have been polished, whether any marks are visible from the polishing wheel, and how defined the edges of each facet are. Since these characteristics are rarely visible to the unaided eye, for an excellent value, look for a polish grade of very good or good, though the higher grades of ideal and
excellent are also recommended. Avoid emeralds with polish grades of fair or poor, as the quality of their polish may affect the brilliance of the emerald. The polish is smooth, without any nicks or scratches.
