Princess Cut Engagement Rings
The Princess Cut is a fancy diamond shape that’s only second in popularity to the Round Cut. The square design offers tremendous fire and brilliance, more than in other square diamonds. Princess cut diamonds are versatile enough for many styles of engagement rings, from channel set bands to elaborate vintage designs.
As with other diamond shapes, Cut is the most important quality to review. Look at each diamond closely before purchase or ask for the help of an expert. In general, we recommend a depth percentage of 65-75% and a table percentage below 75%. Aim for a length to width ratio of 1.00-1.05, meaning the length and width are nearly equal to form a symmetrical square.
Princess Cut diamonds yield a lot from the rough stone, making it a more affordable option than a Round Cut diamond. You can find stunning princess cut engagement rings in white gold, yellow gold, rose gold and platinum. To prevent the corners from chipping, look for a setting with prongs that secure all four corners.
