All About Princess Cuts
A stylish blend of old world sparkle and modern clean lines, a princess cut diamond is endlessly versatile and sure to delight.
These stunning shape diamonds are cut in a similar style to the round brilliant (they're sometimes referred to as a square modified brilliant) for a spectacular sparkle and gorgeous shape.
This guide covers what to look for and how we approach selecting them.

What Makes Princess Cuts Special
Princess cut lab diamonds are a brilliant cut, faceted similarly to rounds to maximize light return and sparkle. What sets them apart is the shape.
The princess cut was developed in the 1960s as a way to capture the light performance of a round brilliant in a square shape. It has more facets than a round, typically around 70 compared to 57, which gives it its characteristic sparkle and occasional crushed-ice appearance.
The square outline and sharp uncut corners give the princess cut a clean, architectural presence that's distinct from any other shape.

Settings for Princess Cuts
Unlike diamonds with a more rounded shape, the sharp points of a princess cut can chip if they're left unprotected. A four-prong setting, with prongs placed at each corner, or a bezel are both excellent choices to make sure your stone is protected from damage.
Solitaires are our most popular setting style for princess cuts. Options such as a diamond band or side stones can add character and dimension to highlight the beauty of your center stone.
We offer a wide range of setting styles for princess cuts, or you can enjoy complimentary custom design support from an Ada Concierge to bring your ring to life exactly the way you want it.

What We Look for in Princess Cuts
Two of the main things we screen for in princess cuts are inclusions and color, both of which can be more visible near the corners in princess cuts.
Like natural diamonds, lab diamonds can vary widely in quality and appearance, even those with similar 4Cs grades. Our team screens lab diamonds for light performance, unnatural color tints, and crystal quality to make sure they look beautiful in real life, not just on the grading report.
Every diamond is inspected in-house before it’s ever offered to our clients, with only the ones that meet our standards making it through.
