At Padis
Jewelry, we know many of our customers often confuse the term
the “cut” of a diamond with the “shape.”
A diamond’s shape refers to the appearance of the stone such as round,
princess, emerald, asscher, marquise, oval, radiant, and cushion. The cut of a diamond refers to the
proportions including depth and width and the symmetry or uniformity of the
facets, which controls the diamond’s brilliance as well as its ability to
reflect light through the top of the diamond.
Before a diamond
is cut, the stone is evaluated to determine its best possible cut in order to
maximize clarity, color, and carat weight.
The most popular shape of diamonds is the round brilliant-cut as it
maximizes the diamond’s ability to reflect light and brightness better than
other fancy shapes. In fact, almost 75%
of all diamonds sold today are round brilliant-cut. The round brilliant-cut typically cost more
than comparable cushion, princess, asscher and emerald shaped diamonds as more
of the stone is lost in the cutting process resulting in a fairly low yield/high
demand for the stone.
According to the Gemological Institute
of American, the 57 or 58-facet round brilliants of today are the result of a
variation of facet sizes and proportions that have evolved throughout many
years. This includes “table size, crown
height, length of the lower half facets, total depth, and culet size.” Round brilliant-cut diamonds with 58 facets
have a culet, which is the small area at the bottom of a diamond’s pavilion or
tip that is cut off and counted as one of the facets. The stone is considered a higher grade if it
does not have a culet or only has a very small, or medium-sized one. A larger culet affects the appearance of the
diamond and can appear as if the diamond has a hole in it.
