The Essential 7C's
Every diamond has its own story, and every lady her own style.
At this point it should be noted that the shape of a diamond
can also be referred to as its “cut”, like a round or princess cut.
However, this should not be confused with the more commonly used term of
diamond cut, which describes how well the diamond has been polished
from the raw material (see section on diamond cut).

The Marquise Brilliant cut may also be referred to as the
"Navette" shape, meaning “little boat,” as the shape of the diamond is
said to mirror the hull of a small boat. It is generally comprised of 58
facets, with 33 on the crown and 25 on the pavilion, although the
number of pavilion facets may range between 4 and 8. Additionally,
Marquise shapes are sometimes cut with a “French tip,” which replaces
the large bezel facet at the point with star and upper girdle facets.
French tips are also used in the Heart and Pear shapes. Even
though the optimal ratio of the Marquise is 2:1, the shape is more
traditionally cut to ratios ranging between 1.85 and 2.10 according to
The Marquise can suffer from a so-called “bow-tie effect” when
light passing through the diamond casts a shadow across the central
facets of the stone. This shadow can be reduced by altering the depth of
the pavilion, and adjusting the angles of the table and facets to
better diffuse light in the central area. This effect also occurs in the
Pear, Oval and Heart shapes.
3. Expert Advice
“The Marquise cut can maximise carat weight, making it
appear larger than other stones of the same size and is often set with
round or pear-shaped side-stones. As with other elongated shapes, the
Marquise can make fingers appear longer and more slender.
It is important that the Marquise is not too shallow so as
to avoid light passing through the back of the diamond and diminishing
its brilliance and fire.”
4. History & Background
The Marquise cut first appeared in Paris circa 1745 and its
fascinating history can be traced back to the height of the French
monarchy. King Louis XV commissioned his court jeweller to create a
diamond that resembled the smile of his beautiful mistress, the
Marchioness Madame de Pompadour. A well-educated and intellectual woman
who exerted strong political opinions on the French court, Madame de
Pompadour was the official maitresse en titre of King Louis XV between
1745 and 1750.
The shape was then developed and modified throughout the 20th
century, evolving into the Marquise Brilliant cut as it is known today,
seeing an especial rise in popularity between the 1960s and 1980s. The
Marquise cut first appeared in Paris in approximately 1745. The
fascinating history of the Marquise cut can be traced back to the height
of the French monarchy reign.
