The princess cut is a square diamond with sharp corners and full brilliant faceting — modern, sparkly, and one of the best values per carat. It has long been a favourite for contemporary rings. The one thing to mind is protecting its pointed corners. Here is the guide.
Key takeaways
- The princess is a square brilliant — crisp, modern and very sparkly.
- It offers strong value per carat because it retains more of the rough crystal than a round.
- Its sharp corners are its vulnerable point and should be protected by the setting.
- The classic ratio is close to square (about 1.00–1.05).
- Its brilliance is fairly forgiving of minor colour and inclusions.
What is a princess cut?
Introduced in the 1960s–80s, the princess combined the brilliance of a round with clean, square lines — a modern silhouette with serious sparkle. It quickly became one of the most popular shapes for contemporary engagement rings, and remains a go-to for anyone who wants geometry and fire together.
Sparkle and value
The princess is brilliant-faceted, so it returns plenty of light and hides minor inclusions and a touch of colour the way a round does. And because cutting a princess wastes far less rough than a round, it usually costs less per carat — making it one of the best ways to get sparkle and size for the budget.
Every centre diamond is Triple Excellent, D–E, VVS and at least three carats — the hard calls are made for you.
Design your ringProtecting the corners
A princess's four pointed corners are where it can chip, so the setting matters. Look for protective prongs (V-prongs or corner claws) that cup and shield each corner. With a well-made setting it wears beautifully for a lifetime.
The best settings for a princess
The princess suits clean, modern settings: a solitaire with corner-protecting prongs, a halo for extra sparkle and size, or channel-set side stones for a sleek, contemporary line. Explore our guide to settings and compare shapes in our visual guide.
