† Calculated estimate from nearby published sizes. Below the smallest reference, dimensions are scaled assuming unchanged proportions. These entries describe an illustrative size, not a measured stone.
Educational estimates. Carat measures weight: 1 ct = 0.2 g. Depth, girdle and proportions affect dimensions, so there is no exact mm-to-carat conversion. Check the individual stone’s measurements and grading report.

A generally square outline and pointed corners give the princess its geometric presence. Pavilion faceting creates an energetic pattern of reflections.
What to consider
Check corner condition and plan a protective setting. Face-up measurements, depth and symmetry matter when building matched layouts.
Ask for the actual measurements, report and images of the stone being offered. A shape illustration cannot establish its appearance, grading or availability.
