Diamond cutting and polishing In its rough form, a diamond is a lackluster, translucent crystal. Transforming a rough diamond into a sparkling jewel requires several procedures: cleaving, sawing, bruting, cross working and brillianteering.
Round cut Round diamonds are the most popular of all the shapes, perhaps because their circular proportions display the most "fire" and reflect more light back to the observer than any other shape. Round diamonds require that more rough be removed during cutting and polishing than with other shapes. The combined popularity of round diamonds and the significant weight loss during cutting are the two main contributing factors to the relatively higher price of these stones.
Emerald cut Emerald cuts are sleek and elegant. The Emerald cut is rectangular with cut corners. It is a step cut - its facets being broad with flat planes resembling the steps of a stair. Higher quality Emerald cuts are preferred because its cut makes inclusions and lower color grades more noticeable than with other cuts. Length to width ratio An emerald cut with a length to width ratio of approximately 1.35:1 is generally the most prized. However, in recent years, square emerald cuts have become extremely popular.
Length to width ratio A princess cut with a length to width ratio of less than or equal to 1.05:1 will appear square to the observer. While a squarer diamond is the preference of many, some people prefer a slightly rectangular-shaped princess diamond.
Diamond Polishing Diamond polishing consists of two phases, crossworking and brillianteering. To give the diamond its finished look, it is clamped to on an armature above a rotating polishing wheel (scaif). Diamond dust on the wheel's surface grinds the diamond down to the desired angle. The scaif makes it possible to symmetrically polish all the facets of the diamond at angles that reflect the most light.
