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).

1. The Basics
Ever the romantic choice... This is a rare and symbolic cut.
|Exclusive heart shape design.
||56 to 58 facets
||Typically 0.90 - 1.10
||Good symmetry is essential.
The heart shape is usually comprised of between 56 and 58
facets, although the number of main pavilion facets may vary between 6, 7
and 8. Additionally, heart shapes are sometimes cut with “French tips,”
which replace the large bezel facet at the point with star and upper
girdle facets. French tips are also used in the Marquise and Pear
shapes. Heart shapes may differ slightly in appearance depending on
their make or structure.
The traditional heart shape should have a ratio between 0.90
and 1.10 and be absolutely symmetrical with the lobes (top arches) of
even height and breadth, although these specifications may be altered
according to personal preferences.
In determining the length to width ratio for heart shapes, the
width is measured at the widest point of the shape from the edge of one
lobe to the other. In addition, the heart shape 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.
3. Expert Advice
"The most important elements to consider with the heart
shape are the quality of the curved cut and finish as these determine
the sparkle of the gem.
The shadow caused by the bow-tie effect 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, Marquise and Oval shapes."
4. History & Background
The exact origins of the heart brilliant are unknown although
being a modified brilliant cut it may have appeared as early as the 16th
century. However, gems which would today be classified as ‘triangular
with rounded corners’ or ‘drops’ were at one time described as being
heart-shaped. Indeed, this is evident from the many descriptions in
French inventories dating from the middle of the seventeenth century.
The first recorded heart shape diamond appears in a portrait entitled
"The Gonzaga Princess,” painted circa 1605 by Frans Pourbus the younger.
The large piece of jewellery on the princess’s left sleeve contains a
variety of different cuts, some of which are thought to be versions of
the heart-like ‘drops’ popular in France at the time. The heart shape is
also mentioned in a book written in 1655 by Jean-Baptiste Tavernier,
the French merchant-traveller who found his fortune in the precious
stone trade and famously brought the Hope Diamond to France. In the
text, he recalls seeing the “Heart Diamond,” a 36-carat heart-shaped
brilliant in an ornament in the treasure of Aurangzeb, in India.
