Diamond Cuts

The cut of a diamond is determined mostly by the initial shape of the rough stone. A well-calculated shape is designed to make the most from the rough diamond into diamond jewellery.

Traditionally, there are ten shapes of diamonds: Round, Princess, Emerald, Asscher, Marquise, Oval, Radiant, Pear, Heart and Cushion. The quality and accuracy of the cut are graded by GIA on a scale between Ideal, Very good and Good.

Round Cut Diamonds

By far the most popular cut for almost any piece of diamond jewellery. The round shape and the balance between all facets of the cut (the table, the pavilion depth, the crown height etc.) create a perfect reflection of the light and are combined to make optimal brilliance, in a wide range of colors.

Princess Cut diamonds

The most popular shape of diamond among the non-round cuts.

Traditionally, princess cut diamonds are square, although different height to width ratios can be found in the market. The length-to-width ratio that is pleasing to the eye is usually between 1 and 1.2. Of course, that depends on the diamond jewellery design and individual taste.

Emerald-Cut Diamond

A rectangular cut that in contrast to princess cut has an open table and rectangular facets. This unique cut is creating an optical appearance that highlights the clarity of the diamond. Emerald cut diamonds have a various spectrum of length-to-width ratio.


Asscher-Cut Diamond

Nearly identical to Emerald cut, the Asscher cut has the same shape – only square. The recommended length-to-width ratio for this cut is between 1 and 1.05, to maintain the square shape. When choosing a color grade for this cut, note that on J color and down, color may be slightly visible in its corners (on all non-round cuts).


Marquise-Cut Diamond

The geometrical shape of marquise-cut diamonds has many advantages: the unusual shape is easily combined into many diamond jewellery designs. More than that, this particular cut maximises the carat weight, resulting in a much larger-looking diamond.

Traditionally, the length-to-width ratio for marquise-cut diamonds is between 1.75 and 2.25.

Oval-Cut Diamond

Similar to round shaped diamonds, the oval-cut diamonds excelled in brilliance. The long shape of the diamond can accentuate long, slender fingers – with the right design, of course.

Traditionally, the length-to-width ratios between 1.33 and 1.66.

Radiant-Cut Diamond

The signature for this cut is the trimmed corners, which gives it flexibility in pairing it other diamonds: it looks great next to both round and rectangular diamonds. If your desired diamond jewellery requires a square stone, go with length-to-width ratios between 1 and 1.05. If you prefer longer, more rectangular shape, look for length-to-width ratios greater than 1.10.


Pear-cut diamonds

With one rounded end and one pointed end, this diamond is also called teardrop. That distinctive shape can add a splash of uniqueness to every diamond jewellery and make it unforgettable. The most traditional pear-shaped diamond length-to-width ratios between 1.45 and 1.75. A more elongated design will require length-to-width ratios between 1.75 and 2.

Heart-Shaped Diamond

Choosing to have the ultimate symbol of love on your diamond jewellery will create a distinctive and unusual look. When selecting a color grade, notice that J color and down, color may be visible in the corners.

Traditionally, the length-to-width ratios between 0.9 and 1.10.

Cushion-Cut Diamond

Popular for many decades, this cut has rounded corners and larger facets, to maximise the brilliance.

If your desired design requires a square stone, look for length-to-width ratios between 1 and 1.05. If your preference is longer, more rectangular shape, go with length-to-width ratios greater than 1.15.
