A short history
The 1980s square brilliant, engineered to keep more rough than any other cut, which is why it costs less per carat than almost anything.

Works with a princess stone
PRICES AS OF 16 AUG 2026How it wears
Four sharp corners want four protective prongs; unprotected princess corners are how insurance claims begin. Geometric, modern, efficient.
The setting it wants
Corner-guard prongs or a channel setting in a band, where its square shoulders sit flush and safe.
What ratio should a princess diamond be?
We buy 1.00. Outside that window the shape starts reading as a different cut, or worse, as a mistake. The passport lists exact millimeter dimensions so you can check our judgment.
How many facets does a princess cut have?
57 to 76. More facets mean more sparkle but smaller flashes; fewer mean bolder, slower light. Neither is better; they are different personalities.
Is princess more expensive per carat?
Fancy shapes like this cost less per carat than rounds, because less rough is lost and fewer buyers compete for them. Same material, better math.
Natural or lab grown in this shape?
Both, cut to the same standard. Lab rough makes larger princess stones attainable; the passport names the origin either way, in the same type size as everything else.
