What is an oval diamond?
An oval diamond is a modified brilliant-cut diamond with an elongated outline and brilliant faceting designed to provide strong light return and larger face-up appearance.
The oval diamond bow-tie effect
A bow tie is a dark shadow pattern across the centre of many oval diamonds. A small amount can be normal, but excessive bow tie can reduce brightness and visual appeal.
Ideal oval diamond ratios
Balanced oval proportions are often around 1.35-1.45, classic elongated oval around 1.45-1.55, and very elongated oval above 1.55.
Oval diamonds vs round diamonds
Oval diamonds typically offer larger face-up appearance and strong brilliance, while round brilliant diamonds remain the classic benchmark for maximum cut-grading structure.
