Princess Cut Diamonds


Princess cut diamonds are generally thought of as square, although they can in fact be quite rectangular when looked at from the top, with the shape at the back being a little like a pyramid when viewed from the underside. Because of this, the general diameter of the diamond is less than in some of the other cut types. This is due to the additional weight distribution in the back of the diamond, leading to less spread across the width of the diamond.

Typically these diamonds have a lower crown with a larger table facet than many other popular cut options. For example a round diamond with “Excellent cut” will have a main top facet ( the table facet ) equal to around 57% of the diamond total width. A princess cut on the other hand can often be over 70 % in this area. These measurements really matter, because they lead directly in to how much of the crown of the diamond remains to offer a return in light refraction – “sparkle”, if you like.

There are quite a number of variants in the princess cut, some with a high crown and others are low and flat looking. Again, how good the cut is is crucial to the overall look of the diamond, and sound professional advice is a must if you want a great looking diamond. Low cost princess cut diamonds will often suffer from issues relating to the symmetry of their cut. For example, they may be off square, rhombic and/or have an off centre pavilion (the back of the diamond). A diamond with these issues should be avoided if the finished ring is to look its best.
