MORE ABOUT SQUARE SHAPE DIAMOND RINGS

Princess cut diamonds and are a brilliant and scintillating choice for engagement rings. The Princess cut is a square diamond with sharp edges in the shape of an inverted pyramid. The best cut are those with a length:width ratio of between 1-1.05 for the most brilliance, avoiding those with a more rectangular shape.
The Princess cut as we know it today, can be traced back to the 1960’s. In 1971, the diamond cutter Basil Watermeyer patented a new diamond cut with the name “the Barion”. This looked already a bit like the princess, but the many symmetrical lines of the Barion made it very difficult to cut this shape correctly. Years later, this name changed into the Princess cut.

Our signature stone Ethica Diamond Princess cut moissanite and most Princess lab grown diamonds have between 50 and 58 facets, depending on how the stone is cut. The majority of the facets are on the pavilion and crown, with some on the girdle. Princess cuts also typically have two to four chevron patterns, which are cross patterns that can be seen when viewing the diamond from above.
A Princess diamond with two chevron patterns reflects bolder flashes of light, whereas a Princess with four chevron patterns will have more scintillation with more abundant, but smaller, flashes of light when the diamond moves.

Choosing the perfect Princess cut stone for your engagement ring is slightly more difficult than selecting a Round Brilliant cut, since the certification does not give any indication for how the stone will sparkle by giving a cut grade. The certificate gives you the grades for the colour, clarity symmetry and polish, but how the diamond actually looks is not indicated on the certificate, since fancy cut diamonds such as Princess cut is not given a cut grade. This is because standard cut parameters are unachievable due to the complex and unique structure of the Princess cut; there is no strict table % or depth %.

For a good balance of brilliance to size ratio, we recommend a depth of 65% – 73% and a table of less than 75%, although the table percentage is more down to personal preference.

The colour we recommend for a Princess cut diamond is between G-H for the best value for money. Being a brilliant cut, the Princess cut has a lot of light play which makes identifying the true colour of the rough material more difficult, meaning you can get away with a lower colour grade compared to other cuts such as Emerald. You can always go higher on the colour grade if you wish but at Ethica, we personally don’t think that the incremental difference you gain in whiteness is worth the much bigger increase in price you’d have to pay.

The Princess cut is a good cut for masking imperfections within the diamond. This means that the budget is better used elsewhere, such as the carat weight. Just be careful not to go too low on clarity though; just because the diamond may be eye clean, inclusions within the diamond are weaknesses within the structure, which makes the diamond more susceptible to chipping. A Princess cut diamond is already more vulnerable to chipping because of its sharp corners, that’s why we recommend a clarity of VS for the best value for money and balance of integrity.

It is best to purchase a Princess cut diamond that is already set within a ring for this reason rather than a loose stone which you then have to have set, since the setting of a Princess diamond is when it is most likely to be damaged. We also don’t recommend unsetting and resetting Princess cut diamonds for the same reason.
You need to ensure that you can view a video of a Princess diamond and ideally get it reviewed by an expert before you buy. At Ethica, we are very happy to take a look at the cut quality of the Princess diamond for your ring and advise you accordingly; just get in touch and we will be happy to help.
We have a collection of Princess cut engagement rings,  as well as the option to purchase a loose Princess cut Ethica Diamond or sustainably grown Princess cut lab grown diamond, which can be set in a piece of jewellery of your choice, or used for a proposal so that you can choose the engagement ring setting together as a couple.
