The oval cut diamond is the most popular fancy shape — romantic, elongating and appearing larger per carat than any round brilliant of the same weight. This guide covers everything about the oval cut.
The oval cut diamond is an elongated brilliant cut — the same 58 facets as a round brilliant adapted to an elliptical outline. The result is a stone with the brilliance and fire of a round brilliant combined with an elongated shape that creates a finger-lengthening effect no round can match.
Oval diamonds appear 10–15% larger than a round brilliant of the same carat weight because the elongated outline covers more finger surface area. A 1.0ct oval appears similar in size to a 1.15–1.20ct round on the hand. This makes oval one of the most efficient shapes for maximum apparent size per dollar.
Every oval diamond has some degree of bow tie — a dark shadow across the central width of the stone. The question is severity: faint bow tie in a well-cut oval is invisible in most conditions. Strong bow tie dominates the stone in all conditions.
