The
length to width ratio of a radiant
cut diamond is important to its value.
Popular diamond quality reports from
GIA and other gemological laboratories
do not provide length to width ratios.
However, they do provide length, width,
and depth measurements. Length to
width ratios are determined by dividing
the length measurement by the width
measurement. Measurements are always
calculated to the one-hundredth of
a millimeter. (Example) Radiant
length equals 6 millimeters; radiant
width equals 4 millimeters; 6 millimeters
divided by 4 millimeters equals a
length-to-width ratio of 1.5 to 1.
The
best radiant diamonds will have a
length to width ratios between 1 to
1and 1.5 to 1. Length to width ratios
within these ranges are considered
by GIA as very fine to ideal. A radiant
diamond's length to width ratio is
largely determined by the original
size of the rough diamond crystal.
When a rare fine quality diamond is
cut by an experienced diamond cutter,
the weight and value will never be
sacrificed simply to change a diamond's
length to width ratio if it is within
the range of 1 to 1 and 1.5 to 1.
