The angular and impressive princess-cut diamond is a favorite choice for women who want a modern, geometric shape with strong lines. Unlike the flashes of light seen in emerald or Asscher cuts, the princess diamond has impressive fire and brilliance, maximizing sparkle.

While it’s a relatively new shape—it was first created in the 1960s—it’s now the second most coveted choice after the round cut. The princess cut continues to increase in popularity, and we can see why. Its clean lines and angles make it a modern, elegant option.

Traditionally, princess cut diamonds have a square shaped surface. They will appear square in shape to the naked eye with a ratio of around 1.05. It is entirely preferential whether you choose a princess cut diamond with these proportions as many are drawn to an elongated princess with a ratio of 1.10 and above.
