Pear
L+W=	1.20	1.40	1.60	1.75	2.00

Preferred ratio: 1.60  |  Range: 1.595-1.645

The optimum ratio for a pear-shaped diamond is about 1.60 (or a range of approximately 1.50 to 1.70). This ensures that the outline has enough length to be elegant. A pear-shaped diamond that is very short and wide (less than 1.30), or too long and narrow (2.00 or more), may result in less brilliance or may be difficult to set properly.
