Princess-Cut Lab-Grown Diamonds for Wholesale Jewelry Buyers
Princess-cut buying briefs should control square outline, corner integrity, physical measurements and compatibility with a setting that protects all four points.
Request princess options
Square outline and measurements
State length, width and the accepted difference between them. A princess cut described as square can still vary enough to affect the setting seat, halo or matched-pair appearance.
Corner integrity
Review all four points for damage, asymmetry and compatibility with the planned prongs. The quotation and shipment checks should identify how the stone is protected during handling.
Facet appearance and grading
Compare the face-up pattern, contrast and clarity visibility using available media. Then connect the selected stone with its report, dimensions, weight and growth or treatment disclosure.
Setting fit and matching
Provide the seat dimensions and corner-clearance requirement. For pairs, compare length, width, square outline, grading relationship and face-up pattern.

How square should a princess cut be?
The buyer should define an acceptable length-to-width tolerance based on the setting and visual standard.
Why inspect the corners?
The pointed corners are vulnerable during handling and require compatible setting protection.
Can princess cuts be matched for earrings?
Yes. Compare dimensions, squareness, grading and face-up appearance rather than carat weight alone.
