Princess cut diamond
The carat is the unit of weight used to measure a diamond. Today, one carat equals exactly 0.20 grams and is one of the four fundamental criteria defined by the GIA for diamond evaluation.
Princess cut diamond
The princess cut diamond has a square or slightly rectangular outline, four sharp corners and brilliant-style faceting, with chevron facets on the pavilion. Developed in the second half of the twentieth century, the princess cut is the most widespread of the square shapes.
It preserves a large part of the rough crystal; at comparable weight, color and clarity, the price per carat of a princess diamond is generally lower than that of a round brilliant. The stone’s tint is slightly more visible in the corners, where more light escapes. The sharp corners are fragile; a setting with V-shaped prongs protects them. For this shape, the GIA report states polish and symmetry but no cut grade, which is reserved for the round brilliant.
All the princess diamonds offered here are GIA certified; the carat ranges give access to the available stones, with their prices in CHF, EUR or USD.
Understanding diamond carat weight
The term carat originates from antiquity, when carob seeds were used as a reference weight for precious stones.
What carat weight really indicates
Carat refers to weight, not absolute visual size.
Two diamonds with the same carat weight may have different dimensions depending on their proportions and how the stone is cut.
At equal weight, a diamond with balanced proportions will present a more consistent visible surface and a clearer overall appearance.
