The shape of a
diamond refers to its profile, while
the cut is more specific than that and is used to allude to the
shape, number and even alignment of its
facets.
Round brilliant is the most popular
cut diamond option for
engagement rings. The
traditional cut maximizes the sparkle of a
diamond, surpassing that of other
cut gemstones.
An
oval cut diamond is popular too, although not as popular as one with a
round cut. Still, there are many other types of
diamond cuts, derived from the
oval shape, such as
marquise,
pear, and
heart, and those are quite fashionable. While a
marquise cut diamond feature two sharp ends, one with
pear cut features a sharp end;
heart cut diamond is an
oval cut gem with a sharp end as well as a cleft.
Rectangular
diamond cuts are also getting popular these days, especially the
princess, the
emerald, the
radiant, and the
Asscher cut. If that is the
shape you prefer, then look for a
princess cut diamond ring, as that is the most popular rectangular option.
