What to Look for in Princess-Cut Diamonds

Symmetry and depth carry a lot of weight

There is no standard cut grade for princess cuts. Check the polish and symmetry in the certificate and look at the depth: Princess cuts are often cut deep, which means a significant amount of weight lies hidden beneath the setting. A length-to-width ratio between 1.00 and 1.05 keeps the outline neatly square; above that, it appears noticeably rectangular.

Colour and Purity for the Square Shape

The corners concentrate the body colour, which is why a princess cut appears slightly warmer there than in the centre. A grade from G to H is a solid compromise. When it comes to clarity, the fine sparkle helps; VS2 and, often, SI1 are eye-clean. Just make sure there are no inclusions located directly in a corner, because that’s the most sensitive spot.

Size in millimeters per carat

A 1-carat princess cut measures approximately 5.5 × 5.5 mm; a 1.5-carat stone measures approximately 6.2 × 6.2 mm; and a 2-carat stone measures approximately 6.9 × 6.9 mm. When viewed from above, the edge length is shorter than the diameter of a round stone, while the diagonal is longer, which makes the stone stand out on the hand.

Frequently Asked Questions

Are the corners of a princess cut fragile?

The four pointed corners are the most vulnerable parts of the shape. That is why they are usually enclosed by prongs that grip the corner precisely. Set in this way, a princess cut is suitable for everyday wear. Without this protection, there is a greater risk that a hard impact could chip off a corner.

Does a princess cut look smaller than a round diamond?

From above, yes, because at 1 ct, the edge measures about 5.5 mm, compared to about 6.5 mm in diameter for a round cut. The diagonal, however, is larger at about 7.8 mm. The impression depends heavily on how deep the stone is cut.

What clarity grade is appropriate for a princess cut?

VS2 is a good baseline; SI1 often works as well, because the faceting pattern refracts small inclusions. More important than the clarity grade is that nothing is located in or near a corner. You can determine the position of the inclusions from the diagram on the IGI or GIA certificate.

What is the difference between a princess cut and an Asscher cut?

Both are square; the rest is the opposite. The princess cut has sharp corners and brilliant facets, so it sparkles with fine, intricate details. The Asscher cut has rounded corners and a step cut that produces subtle flashes of light. The Asscher cut requires a higher level of clarity, while the princess cut is more forgiving in this regard.

Lab-grown diamond or natural diamond?

Lab-grown diamonds and natural diamonds are both composed of pure carbon and share the same crystal structure, hardness, and refractive index. The difference lies in their formation: one forms over millions of years in the Earth’s crust, while the other is created in a matter of weeks in a laboratory. Visually, they are indistinguishable without specialized laboratory equipment. Lab-grown diamonds are significantly less expensive than comparable natural diamonds, which is why you can often get more carats or a higher clarity grade for the same budget. Both types are certified by IGI or GIA; you can look up the report number directly with the lab.
