| In many ways, the cut of a diamond is the least understood of the 4 Cs. It is
often thought that the cut of a diamond refers to whether it is, for example,
round or oval. In fact, the term “cut” covers not only the shape of the stone, but
also its angles, proportions, polish and symmetry.
The way a diamond is cut determines how light enters and leaves the stone,
which determines how much “life” and “fire” it has. An ideal-cut round diamond
has 56 different surfaces, or “facets.” Those on the crown or top gather light
into the center of the stone, while the pavilion’s facets bounce the light back
and forth before reflecting it back out through the crown.
Only a small deviation in the angles or shapes of the facets will allow light to
“leak” from the stone and cause it to lose much of its natural brilliance. This
also occurs if, for example, too many facets are cut into the stone, the table is
too large or poorly centered, or the girdle is too thick. Many people in the trade
think that cut is the most important of the 4 Cs, as a well-cut diamond will look
more beautiful to the eye than a less well-cut stone. Sam’s Club® uses only the
most skilled diamond cutters, and every diamond is reinspected before it is
shipped to make sure we have the very best quality. |
