The Marquise Diamond is one of the most popular modified brilliant cut of diamond available at the moment. The Marquise Cut or Navette Cut casts its origins way back to the early 18th century when the French King Louis XV ordered a diamond to be cut to resemble the smile of his mistress the Marquise de Pompadour.
The Marquise Cut is also known by the name the Navette Cut because of its likeness to the hull of a sailboat, as navette is French for "little boat". Its appearance has also been likened to an elongated rugby ball, for the sports fans reading this, when viewed from above.

The popularity of the cut soared throughout the 1970's and reached a pinnacle during the 1980's. Still poplar today it is probably the fourth most popular cut behind the Round Brilliant Cut, the Princess Cut and the Oval Cut.
The Marquise Diamond Cut, as it is a modified brilliant cut has the typical facet arrangement and facet count of 58. The Marquise Diamond works best as the heart of a trio, flanked by two smaller Round Brilliant Cuts or just on its own as a solitaire. The ideal ratio that would deliver the greatest the amount of fire and brilliance would be a length to width ratio of 2:1, however a ratio of between 1.75 and 2.25:1 would be perfectly acceptable, with a depth percentage of between 59%-63% being ideal.
