DIAMOND SHAPE Since all diamond cut styles are very different, unique characteristics determine quality for each shape.
Asscher-Cut Diamond:
This beautifully unique shape is nearly identical to the emerald-cut, except that it is square. Also, the Asscher-cut diamond shape has a pavilion that is cut with rectangular facets in the same style as the emerald-cut. If you choose SI-clarity be sure to view the clarity plot on the diamond certificate, because this shape highlights the clarity of the diamond. When choosing a colour grade, consider that while the price of a J-colour non-round diamond is exceptional, colour may be slightly visible in its corners. All Asscher-cut diamonds from Blue Nile will appear square, because each one is guaranteed to have a length-to-width ratio between 1.00 and 1.05;
Marquise-Cut Diamond:
The shape of a marquise diamond can maximise carat weight, giving you a much larger-looking diamond. This brilliant-cut diamond looks beautiful set with round or pear-shaped side stones, and the length of the marquise diamond makes fingers appear long and slender. To find the dimension of marquise you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. The length-to-width ratio will determine the diamond’s outline, or what it will look like when viewed from the top. For the most traditional marquise-cut diamonds, look for length-to-width ratios between 1.75 and 2.25;
Oval-Cut Diamond:
An oval diamond has beautiful brilliance that’s similar to a round diamond. Oval diamonds are also very popular as their length can accentuate long, slender fingers. To find the dimension of oval you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. The length-to-width ratio will determine the oval diamond’s outline, or what it will look like when viewed from the top. For the most traditional oval-cut diamonds, look for length-to-width ratios between 1.33 and 1.66~15.jpg
