The round brilliant cut is the most popular and the most researched diamond shape. Thanks to nearly a century of advanced studies and techniques used by scientists and cutters, this versatile shape gives buyers many options to match cut, color and clarity of a diamond with the desired brilliance (light reflection) and fire (flashes of color). For optimal brilliance, choose the ideal or very good cut, and the ideal, excellent or very good polish/symmetry.
This popular non-round diamond can be square or rectangular (when seen from above), with pointed corners. Thanks to exceptional brilliance, it is frequently seen in engagement rings. Princess diamonds represent a wide spectrum of length-to-width ratio. The perfect square has a ratio between 1 and 1.05, and the traditional rectangular shape starts with the ratio of 1.10.
A typical emerald diamond, when seen from above, is a rectangular. It has a uniquely cut lower portion (pavilion) and a prominent top surface (table), which emphasizes clarity. The rectangular outline is determined by the length-to-width ratio. The most highly valued emerald diamonds have the ratio between 1.30 and 1.40. This ratio, as well as clarity and color are some of the key characteristics to consider while choosing an emerald diamond.
This exclusive shape, named after the Asscher brothers of Amsterdam , is also known as the square emerald. Its pavilion is cut in a similar way, but it is deeper compared to the emerald, and the table is small and square. This unique shape accentuates clarity and color. Therefore, while shopping for an Asscher diamond, try to choose one with the clarity grade of SI or higher, and the color grade above J.
The marquise diamond has an elongated shape and pointed ends, which maximizes the carat weight and makes the gem appear larger. A marquise diamond ring can be very flattering to the hand, because this slim shape beautifully compliments slender fingers. For marquise-shaped diamonds, the traditional length-to-width ratio (which determines the diamond’s outline when viewed from above) ranges between 1.75 and 2.25.
The oval is a very flexible shape that tends to look bigger than other diamonds of the same carat weight. It is elongated compared to the round diamond, but can posess similar brilliance. This popular shape looks especially beautiful on long, slender fingers, but it can also flatter shorter fingers, making them appear slimmer. A classic oval-shaped diamond has the length-to-width ratio (which determines the diamond’s outline when viewed from above) between 1.33 and 1.66.
The characteristic trimmed corners make the radiant-cut diamond a popular and versatile option, which combines the rectangular emerald shape with the brilliant cut. The rectangular outline varies depending on the length-to-width ratio (which determines the diamond’s outline when viewed from above). The square radiant diamond has a ratio between 1 and 1.05, and the traditional rectangular starts with the ratio of 1.10. This flexible diamond shape looks great in a variety of settings – both as a solitaire gem and when paired with baguette or round side-diamonds.
This uniquely shaped diamond – rounded on one end, with a single point on the other end – resembles a teardrop and lends itself beautifully to various types of jewelry. When set in a ring, the elongated pear-shaped diamond elongates the finger, making it appear more slender. The diamond’s outline viewed from above is determined by its length-to-width ratio. When choosing a pear-shaped diamond, look for a ratio between 1.45 and 1.75.
This distinctive shape speaks for itself, and it adds special meaning to any piece of diamond jewelry. As with any other shape, the heart diamond’s outline, when viewed from above, is determined by its length-to-width ratio. A traditional heart-shaped diamond will have a ratio between .90 and 1.10. When choosing a heart-shaped diamond, pay special attention to its color grade, since lower grades (J and below) may cause the color to be visible in the corners.
This unique shape, with rounded corners and large facets ( polished surfaces positioned at different angles), emphasizes brilliance and clarity. Cushion-cut diamonds can be square or rectangular, depending on the length-to-width ratio, which determines the diamond’s outline viewed from above. The square cushion-cut diamond will have a ratio between 1 and 1.05 and 1, and the traditional rectangular shape starts with the ratio of 1.15.
