A marquise cut is an elongated brilliant pointed at both ends.
In more detail
It is the most stretched common outline, with two points, so it is the hardest to cut without a bow-tie. GIA's marquise guide says that marquises typically show some bow-tie. But our Marquise and DG-Bowtie share a 2.06-to-1 outline and 87 facets, and only DG-Bowtie has a band. The points need protection in a setting, usually V-prongs.
On a grading report
No GIA cut grade; measurements as length × width × depth.
