Popularly used for engagement rings as well as earring studs, the princess cut has a square (or sometimes a rectangular) shape when looked at from above, and from the side it looks like an upside-down pyramid.
Developed in the 1960’s and sometimes called a quadrillion, it is a modified brilliant cut and offers great fire and brilliance, but be sure to find one with a higher color grade, as yellow tints are easy to spot in this cut.
Princess-cut gemstones work well in a variety of styles from modern to vintage and are right at home in just about any setting including three-stone rings, solitaires, halos, and channels. Because the process of cutting princess-cut diamonds produces a larger yield than round cuts, they can be cheaper than their round counterparts.
