Looking for a specific style? Choose from our collections below:

A princess cut diamond is a square-shaped stone known for its clean lines and sharp corners. Rivalling even a round cut diamond for its dazzling brilliance, a princess cut displays a beautiful amount of sparkle — making it the perfect choice for those who prefer a modernised, sleek look.

A princess cut engagement ring is the perfect alternative to those who seek a more contemporary look to the traditional round cut engagement ring without compromising on sparkle. The sharp, symmetrical lines of a princess cut diamond allow the facets to reflect the maximum amount of light, resulting in the dazzling brilliance that round cut diamonds are more typically known for. Those who appreciate refined elegance and sleek geometric designs will value the chic look of a princess cut engagement ring.

Lab grown princess cut diamonds possess the same chemical composition, crystal structure, and physical properties as mined diamonds, making them virtually indistinguishable. They are also more ethical, sustainable, and often more affordable, making them an excellent choice for engagement rings and other jewellery.

The price of rings with princess cut centre stones at Cullen varies based on factors such as the chosen gemstone, carat weight, and setting design. We offer a range of designs to suit different budgets, and our team can help you find or create a ring that meets your preferences and price point.​

Although the princess cut has the word ‘princess’ in its name, this stone shape is not associated with any particular princess. In fact, the name was given to this type of cut because, when viewed from above, the facets of the diamond resemble a crown or tiara. Despite the fitting name, neither Kate Middleton nor Princess Diana’s engagement rings feature a princess cut diamond.

Yes, we offer complimentary resizing for all our engagement rings. If your ring doesn't fit perfectly, simply contact us, and we'll adjust it to ensure a comfortable fit.​

All gold and platinum jewellery from Cullen comes with a lifetime manufacturing warranty. This warranty covers any defects in materials or workmanship, giving you peace of mind that your ring is crafted to the highest standards.​
