Marquise
L+W=	1.60	1.80	2.0	2.25	2.50

Preferred ratio: 2.00  |  Range: 1.945-2.055

The marquise is usually cut to a 2.00 ratio (or approximate Range of 1.75 to 2.25). This ratio gives the shape a distinct length and elegance, but provides a good balance of width that is very pleasing to the eye. Very short and wide (less than 1.50) may be difficult to tell apart from an oval, and extremely long and thin (2.50 or more) may lack brilliance and be very difficult to set properly.
