Properties
| Property | Value | Authority |
|---|---|---|
| How it holds the stone | Prongs formed into a V so that they cup a corner or point rather than gripping a flat edge. [1] | — |
| Security | Protects the areas most susceptible to chipping. GIA prescribes V-shaped prongs for the princess cut specifically because its corners are vulnerable, and lists partial bezels alongside them for the same job. [1] | — |
| What to watch for | This is the setting that answers the cuts collection. A princess cut’s corners chip because they lie close to a cleavage plane — a direction in which the diamond’s atoms are less tightly bonded, so it breaks more readily. Marquise, pear and heart shapes have points with the same exposure. Buying one of those shapes is not the problem; buying one without a setting that guards its points is. [1] | — |
