This
diamond cut became popular in the early part of the 20th century
after the publication of Marcel Tolkowsky’s work on diamond ideal cut.
Tolkowsky’s work led to some reformation in the cushion cut diamond.
Improvements were made to the culet and table and cut angles of the diamond and
these improvements led to an increase in the diamond’s brilliance, making it
more brilliant than the older cushion diamonds and more popular among diamond
buyers.
One
of the reasons why cushion diamond is very appealing is because of the fire
that it exhibits. This is its selling point because, even though it is a
brilliant diamond, it is not as brilliant as many other diamonds like the round
diamond.
The
facets of cushion diamonds have three different patterns. The pavilions of the
diamonds with this third pattern have another row of facets in them and are
classified as the modified cushion by the GIA. This modified cushion cut may
have a needle-like facet pattern or an ice crushed facet pattern. This pattern
looks more like the radiant cut diamond than the traditional cushion cut
diamond.
The
cushion diamond can come in both square and rectangular shapes. You need to pay
attention to the length to width ratio of the cushion diamond that you are
buying. A cushion diamond with a length to width ratio of 1.00 will have a
square shape while a cushion diamond with a length to width ratio of 1.10 –
1.20 will have a rectangular shape.
In
choosing the color grade of your cushion cut diamond, you have to pay attention
to the setting you are placing the diamond in. If you are placing it in a white
gold setting, you can settle for a grade H color or even go as low as grade I
or J. If you are going for a yellow gold or rose gold setting, grade I or J is
more appropriate. This will help you save some cash as you don’t have to settle
for the colorless diamonds when particular settings can make a near colorless
diamond appear colorless.
The
facet pattern of cushion diamond plays a huge role in the clarity of the
diamond. The arrangement of the facet in each pattern affects the diamond
clarity. The crushed ice pattern tends to hide impurities in the diamond. While
the chunky facet pattern, on the other hand, do not hide impurities in the
diamond but rather reveal them.
