Good proportions for a Princess cut diamond involve a balanced length-to-width ratio, table percentage, depth percentage, and symmetry. A recommended range for the length-to-width ratio is approximately 1.00 to 1.05. The table percentage should be between 65% and 75%, ensuring a proper balance between brilliance and light dispersion. The depth percentage is ideally between 65% and 75%, allowing for optimal light reflection without excessive depth. Symmetry is also crucial, with symmetrical facets and sharp corner points. It's important to remember that these are general guidelines, and personal preference and individual diamond characteristics should be considered when selecting a Princess cut diamond. Lab Grown Princess Diamonds are great option allowing you to maximize size for a limited budget.
