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.

diamond cut, which describes how well the diamond has been polished
from the raw material (see section on diamond cut).

One of the first cuts to be used in jewellery, the emerald cut
is a rectangular shape with truncated corners and a broad and flat
plane that resembles stair steps when viewed from above. This style is
referred to as a ‘step cut’. The emerald is usually comprised of 57
facets (with 25 on the crown and 32 on the pavilion), although the
number of rows of facets on both the crown and pavilion can vary,
altering the total number of facets for this cut.
While it typically has less fire and brilliance than brilliant
cuts, the broad flat plane of this shape highlights the clarity of a
diamond and its natural crystalline rectangular growth. Additionally,
the flat planes of the edges allow for a variety of side gemstones such
as the long thin rectangular diamonds that often flank this cut, known
The vast majority of emerald cuts have length to width ratios
between 1.30 and 1.50 with 1.40 considered as the “ideal"" or most
popular. Those who prefer a more squared shape will opt for lower ratios
while those after a more rectangular cut will choose higher ratios.
Emerald ratios outside this range are atypical and generally less
3. Expert Advice
"Because of its large open facets, higher clarity grades
(VS2 and above for GIA and VS1 and above for EGL, to ensure it is
completely eye clean) are usually recommended for emerald cut diamonds.
As with the Asscher and Cushion cuts, more rectangular shapes (larger ratios) help to elongate shorter fingers."
4. History & Background
The exact origins of the first emerald cut remain somewhat
ambiguous, although its stylistic specifications can be traced back to
the single table cuts of some 500 years ago and the multi-faceted table
cuts of the Art Deco period in the early 20th century.
The term “emerald cut"" only began being used during the Art
Deco period, despite the fact that diamond cutters were already cutting
the same shape under different names. Initially, the cut itself was
developed specifically for emerald gems in order to reduce the amount of
pressure exerted during cutting and to protect the gemstone from
chipping. However, diamond cutters soon realized the importance of this
cut and applied it to diamonds as well.
