Marquise
The marquise shaped diamond is the second most popular
diamond shape. Approximately 18% of the diamonds sold are marquise
shaped. We look for marquise diamonds that are between 1.75 to
l.00 and 2.25 to l length to width ratio. The way to find
this number is divide the length of the stone in millimeters by
the width.
The most preferred length to width ratio is right in the
middle around 2.00 to 1.00. Also we like to stay with depth
percentages at 65% and under. The table percentage
that we strive for is between 53%-65%. We avoid stones
with a strong bow tie effect, which is a sign that the
stone is cut too shallow. This shape is elegant and a lot of brides
to be like it if they are looking for a more unusual ring.
Pear
The pear-shaped diamond is an unusual shape in that it is somewhat
asymmetrical. It is rounded on one end and pointed on the other.
This shape usually contains 56- 58 facets. For this particular
diamond, we like to stay in the 1.75 to 1.00 length to width ratio
to 1.50 to l.00.
This number is found by dividing the width by the length in
millimeters. We look for the stones that are 65% and under to
about 58% depth. The table percentages are between 53%-65%. This
stone is also beautiful and brilliant and when properly cut shows
very little bow-tie effect. You can select this diamond for the
bride that likes unusual shapes.
Emerald
Emerald cut diamonds are a very classic cutting style . They
are the most difficult shape for a cutter to cut. It generally
takes a diamond cutter approximately 12-14 hours to cut an emerald
shaped diamond. The emerald cut diamond is rectangular in shape,
step cut with diagonally cut corners. The preferred length to
width ratio on an emerald cut diamond ranges from 1.50 to 1.00
up to 1.75 to 1.00.
On the emerald shaped diamond we like to stay in the SI1 and
above clarity grades as there is not a lot of facets to hide the
identifying characteristics. Generally the bride that chooses
the emerald cut diamonds prefers a more simplistic looking ring
and doesn’t care for a “ flashy” look.
