The Princess Cut generally has either 50 facets (21 crown, 4 girdle, 25
pavilion) or 58 facets (21 crown, 4 girdle, 33 pavilion), depending on how the
pavilion is cut.
According to Harold Newman's "Illustrated Dictionary of Jewellery", the term
Princess Cut was previously applied to what is now known as the "Profile Cut"
developed by Arpad Nagy of London in 1961.
The Princess Cut was designed for weight retention of octahedral Diamond
crystals, helping to create more attractive Diamonds at more reasonable prices.
The Barion Cut was the forerunner of the Princess Cut and was invented about 30
years ago by Basil Watermeyer of Johannesburg. The Barion Cut has been the
subject of patents that have expired within the past ten years and this has led
to the greater availability of similarly cut gemstones. The style now known as
the "Princess Cut" has become a generic style of cutting.
The Princess Cut, technically known as "Square Modified Brilliant Cut", is a
square version of the Round Brilliant Cut with sharp, uncut corners and numerous sparkling facets.
The optimal ratio (length/width) is between 1.00 and 1.02.
It is a relatively new cut and often finds its way into solitaire engagement
rings. Flattering to a hand with long fingers, it is often embellished with
triangular stones at its sides. Due to its design, this cut requires more
weight to be directed toward the gem's depth in order to maximize brilliance.
The princess cut tends to be the smallest of the shapes for the same carat
weight since the cut is basically an upside down pyramid with most of the carat
weight in the pavilion or bottom of the stone.
