When selecting a princess cut diamond, you should avoid stones that have a table % that is larger than the depth % for optimum brilliance. My personal advice is to stick with a minimum of G color and SI1 clarity (it’s just my personal preference).
|Table %||64% – 75%||60% – 80%||56% – 82%||Outside Ranges|
|Depth %||64% – 75%||60% – 78%||58% – 80%||Outside Ranges|
|Polish/Symmetry||Excellent – Very Good||Good||Outside Ranges|
|Length to Width (Square)||1.00 – 1.02||1.00 – 1.04||1.00 – 1.05||Outside Ranges|
|Length to Width (Rectangle)||1.5 – 1.75||1.76 – 1.85||1.86 – 1.99||Outside Ranges|
|Girdle Thickness||V. Thin – Slightly Thick||V. Thin – Thick||Outside Ranges|
|Culet Size||None||Very Small||Small||Outside Ranges|
* Note: The table should be used as a reference only.
One of the most common mistakes that people make when buying fancy cuts is to buy sight unseen. To avoid such problems, I highly recommend that you work with vendors that offer photography technologies or enable you to check out the diamond with a virtual loupe before you lay down the money.
