diamond cuts

CARAT
The weight of a diamond is measured in carats. Each carat is divided into 100 parts called points. A 1.25
carat diamond is the same as 1¼ carats or 125points. Large diamonds are found less frequently in
nature, therefore the more carats your diamond weighs, the rarer it is.

Round Brilliant

The round shape is the most popular, often used as a solitaire in engagement rings, earrings, or pendants. It’s estimated that 75% of all diamonds sold are round-shaped and according to research by The Knot, 53% of engagement ring center stones are round.

Pear

The pear shapes trace their history to the 1400’s, with the brilliant style being added in the 1700’s. Pears have gently rounded shoulders and wings (the sides near the point) for an appealing outline. The point should always be directed out toward the fingers of the wearer, and the shape has a slimming effect on the hand. This shape is similar to the marquise shape, in that symmetry is extremely important.

Marquise

The marquise shape was named in 1745 for the Marquise de Pompadour, mistress of Louis XV of France. The long and narrow shape, said to resemble the shape of the Marquise’s mouth, creates an illusion that the diamond is of greater size. Symmetry is quite important with this shape, as even the slightest difference can create and uneven, imbalanced look.

Oval

The oval shape has probably the longest known history, with the first mention of an oval shaped diamond occurring in 1304: the famous Koh-I-Noor, which now resides in the Tower of London. One of the most notable oval brilliant cut diamonds is the 184 carat Victoria, which was cut in 1887. The oval brilliant was popularized and modernized in the 1960’s. Containing fire and brilliance, the oval is suggestive of the round shape but is more unique. This shape also creates an illusion that the finger is longer and slimmer. The oval can be narrow or wide, depending on personal preference.

Emerald

An octagonal shaped diamond, the emerald cut was designed to highlight the qualities of emeralds. This cut is highly coveted due to its square or rectangle table-top cut and step-cut facets. The emerald cut’s smoothly beveled corners add visual appeal and provide a secure setting area for the prongs. This cut results in a more mirror-like look and requires a stone of very high quality.

Asscher

The Asscher cut. Developed in 1902 and named after its creator, Joseph Asscher. It was also a popular cut for Art Deco jewelry. It is similar to the emerald cut, though it differs in that its facets are larger and it tends to be square rather than rectangular. Around 2002, this cut became popular again as modifications were made to the cut.

Princess

A relative newcomer to the diamond universe, the princess cut was created in 1981 by Betzalel Ambar and Israel Itskowitz. GIA grading reports describe princess cut diamonds as square modified brilliants, distinguishing them from the step cut facet arrangements you find on other square diamonds like the Asscher cut. A princess cut diamond can also be rectangular or tapered. The princess cut is like an upside-down pyramid, with much of its weight in the pavilion, so the face-up appearance of the finished diamond may appear smaller than another diamond of a different shape but of similar carat weight. The number of facets and the faceting arrangement on the pavilion and crown can vary widely, creating a wide variety in scintillation, the combination of how much it sparkles and the pattern of the sparkle.

Radiant

A radiant cut diamond has an eight-sided outline, and is typically square or rectangular in shape with cut corners. Now branded as The Original Radiant Cut, this diamond cutting style was patented in the late 1970s by Henry Grossbard, but others have since replicated the style after the patent lapsed.

The radiant cut is a mix of step cut facets on the crown and brilliant cut facets on the pavilion. Its angular shape and brilliant cut facets make it an alternative to either the round brilliant cut or the emerald cut. Unlike the emerald cut which favors diamonds of exceptional clarity, a radiant cut diamond can be more forgiving of inclusions.

Like other modified brilliant cuts, the radiant cut has the remarkable ability to transform a diamond’s color appearance, making the color appear either lighter or darker when viewed from above. Sometimes a colored diamond will be recut into a radiant to improve its face-up color.

Heart

The heart shape diamond can be a beautiful symbol of love and romance. A skilled cutter creates the heart shape, always keeping an eye on the heart’s balance and symmetry. This shape is ideal as a pendant and is very popular around Valentine’s Day.

Baguette

The baguette cut. Named for the French word baguette, which means “long rod,” this cut became popular during the 1920’s, an era when the Art Deco movement encouraged geometric shape and symmetrical flow. This cut is generally used for smaller side stones. They are often measured by dimensional size, rather than carat weight.

Trilliant

Triangular shaped diamonds first made their appearance in the 1500’s. Brilliant cut versions of this shape gained popularity in the 1960’s with the appearance of a variation called Trillion. In 1978 an additional variation called the Trilliant came on the market. It was developed as a triangular version of the square-shaped radiant diamond and is sometimes considered an adventurous and provocative diamond choice.
