What are a Princess Cut Diamond’s Dimensions?
The princess cut is a sharp square with four sloping sides. It is designed from the inverted pyramid of a diamond stone. The cut can have anywhere between 50 and 58 facets.
The highest quality princess cuts are those with an obvious square shape with a length-to-width ratio of 1.00 - 1.05.
About the Princess Cut Diamond
One of the most popular cuts, the princess cut is also one of the youngest. In 1961, Arpad Nagy, a diamond cutter based in London created the profile cut. It was also referred to as the princess cut at the time. But it didn't become the standard name for many more years. This cut shows off the diamond’s sparkle without sacrificing too much of the rough stone.
The princess cut is the second most popular choice for engagement rings. It accounts for 30% of them. But this cut is also popular in necklaces, earrings, and bracelets.
Maximising Your Princess Cut Diamond’s Size
Big-carat Princess Cut Diamond Ring
Princesses look smaller than most diamonds of the same weight except for Asschers. This is because most of its weight is hidden in the pavilion. But you can compromise a little on clarity and color grades to increase the carat weight. Plus, the princess cut has a brilliant shine.
A princess cut is not as good as round brilliants at masking inclusions, but it’s still very, very good. A cut with a clarity grade of VS2 and SI1 will have inclusions and flaws concealed quite well.
Princess cuts show color slightly more than round cuts, but not as much as step cuts. An I grade stone will look perfectly fine on white or platinum setting. If you favor yellow or rose gold, a princess cut with J grade is fine.
FAQ
Does a princess cut diamond sparkle?
Yes. Princess cuts have exceptional sparkle, second to round diamonds.
What looks bigger, princess cut or round?
A princess cut diamond looks larger than a round cut diamond of the same carat size. This is because princess cut stones have larger tables than round cut stones.
Is a princess cut diamond worth it?
Princess cut diamonds are always less expensive than an equivalent round cut diamond. This makes princess cuts a better option for those on a budget. A 1 carat stone for example, might be more affordable in a princess cut. The same budget might only buy a 0.70 - 0.80 carat round cut of the same quality.
