QUALITY SCALE
PRINCESS-CUT DIAMONDS

Untreated
Princess cuts are deep, so they are heavy relative to their face-up appearance. In other words, a princess cut will look smaller face-up that other shapes of the same carat weight. When comparing their per-carat prices to those of different cuts with comparable quality, they will seem to be relatively inexpensive. However, a gemstone's value should be judged by its apparent size and beauty. True value is better realized if one does not meaninglessly insist on a certain carat weight, and it is especially important to keep this in mind when judging the value of princess cuts.

The value of one-carat-size princess-cut diamond of jewelry quality is approximately US $4,000 for the stone alone. (2001)
