The cut was made as it was ordered and has since been referred to as the Marquise cut.

Since marquise cut diamonds are exquisitely lengthy and slim just as it is with the oval diamond, they have the tendency to form the illusion of a bigger dimension. In matters of carats, this cut diamond has one of the widest crown surface areas of any shape of the diamond. This all the more makes it a preferred pick when a buyer is looking to put the perceived size or appearance of a diamond to use.

Marquise cut diamonds features an extent of the bow-tie, ranging from being almost invisible to very severe degrees. This effect implies that when a light goes through the diamond, it projects a shadow across the facet of the diamond cut. The extent of this shadow can be minimized by changing the pavilion and modifying the angles of the facets as well as the tables to exquisitely disperse the illumination on the central region of the diamond. This bow-tie effect can also be seen in Oval, Pear and Heart shapes. The presence of a bow-tie effect is not easily checked just by going through the dimensions or certificate of the diamond, it can’t also be perfectly imagined.  However, it can only be ascertained by physical and on-the-spot inspection.

Although it cannot boast of the same reputation as some other diamond cuts, it can sure drive at almost the same level of competition with them. It features twenty-five (25) facets on the pavilion and comes with thirty-three (33) on the crown. However, the number of facets on the pavilion may vary within four (4) and eight (8). In addition, the shapes of this diamond cut are sometimes fashioned with a ‘French Tip’ which takes the place of the big bezel facet at the position with star and upper higher girdle facets.

In Pear and Heart figures, French tips are more often used. Although the optimum length to width ratio of this diamond cut is two to one, (2:1), it is often cut in traditional settings to ratios varying within 1.85 to 2.10 with respect to personal choice and disposition.

It is important to note when going for a piece of choice jewelry coming with a Marquise cut that the pointy ends have to be well secured. This is pivotal for the safety of the diamond cut because if the pointy ends are not well secured, it can easily get the diamond cut damaged and compromised. A good practice is to have claws built around the pointy ends of the Marquise cut to an appreciable extent. With prongs set around the two pointy ends, the Marquise cut diamond is protected from any possible tendency of chipping. For the fact that these points once closest to the external edge of the unrefined stone, flaws, and blemishes such as extra facets, naturals, and some other inclusions may be found in this region. But since there will be prongs and claws protecting these points, these flaws and blemishes are not easily seen as soon as the diamond is refined and set. However, the only thing you had had to worry about is if these flaws will be large enough to disturb the stability and firmness of the diamond, although this is just very rare and hard to come by.

A key determinant in choosing the best length to width ratio is a lot based on your disposition and preference. Your personal choice should determine the extent of narrowness or wideness of your Marquise cut diamond.

When it comes to going for the best Marquise cut diamond, symmetry also ranks high on the list of things to look out for. The two pointy ends should balance each other. Also, the left and right sides should align in such a way that they form an almost mirror image.

This is the more reason why the need for a superb symmetry cannot be overemphasized.

With a length to width ratio of 1.75, a Marquise cut diamond is usually a bit stockier which may imply greater durability as compared to when the cut is coming with higher ratios. At 1.95 lengths to width ratio, a Marquise cut diamond will appear slimmer and maintain a minimal amount of stability. At 2.15 lengths to width ratio, a Marquise cut diamond will appear more elongated and maintain a lesser amount of durability as compared to others.

The cut grade of a Marquise cut diamond is representative of the quality of the ratio and symmetry of the diamond. The GIA and AGS do not designate any cut grade to this cut but the however designate symmetry and polish grades. This thus makes Marquise cut’s grade to be determined by most retailers by its propositions, symmetry as well as its polish. This is because these parameters are good approximations of sparkle given that a true cut grade isn’t available.

Table% – Marquise’s cuts are considered poor, fair, good, very good, or excellent when they have their table percentage in the ranges < 50 or > 70, 50 or 69 – 70, 51 or 66 – 68, 52 or 64 – 65, or 53 – 63 respectively.

The depth percentage refers to how much light the diamond will reflect the depth percentage is indicative of the amount of light that the Marquise cut diamond will readily reflect. As regards the depth percentage, the cut is considered poor, fair, good, very good, or excellent when it has < 50 or > 74, 50 – 52.9 or 71.1 – 74, 53 – 55.9 or 66.1 – 77, 56 – 57.9 or 62.1 – 66, or 58 – 62 respectively.

When it comes to girdle, a very thin to a fairly thick one connotes an excellent and very good cut. It is good when it is within very thin to thick, fair when within very thin to very thick, and considered poor when the girdle is within very thin to an extreme thick parameter.

When the cut has no cullet, it is considered excellent. The cut is very good when it has very small cullet, good when it has small cullet, fair when it has medium cullet, and poor when the cullet falls any greater than medium.


When it comes to examining color in this cut, it is best determined based on personal choice and individually biased. Be aware of the fact that most buyers may choose to go for the fairly warmer colors of the G-H diamond instead of the D-F type which is usually frigid colorless. Truth is that most Marquise cut with color on the extreme side and with high prices is usually steered largely by demand and supply. When customers are in dire search for the D-F color types, they are ready to pay more to get their hands on it. If the concept of color grading were not present at all, higher grade diamond will come at a lower premium price because the distinction between colors will be very hard to know. So, slight color differences will not be obvious and thus wouldn’t weigh at all on the scheme of things.

With Marquise cut diamonds that have larger size and surface area, i.e. above one (1) carat, the color may seem to look quite darker at the point ends. This is the exact reason why buyers usually decide to reach up to one step higher in color grade as compared to the rest kind of diamond cuts.
