Lab Grown Princess Cut Diamonds
A princess cut is a square stone with brilliant faceting, so it keeps much of the fire of a round in a sharp geometric outline. It is the most popular of the square shapes and the most contemporary looking.
Use the filters above to narrow this lab grown princess cut inventory by carat, colour, clarity and cut. Prices move with live supply, so the stone you are looking at is the stone available today, and every one is sold loose with its grading report.
Choosing a princess cut diamond
The four corners are the thinnest points on the stone and the most vulnerable to chipping, so a setting with claws that cover them is worth insisting on. Princess also loses far less rough in cutting than a round, which is why it is consistently better value per carat.
Lab grown or natural princess cut?
Every stone on this page is lab grown. If you want to price the same princess cut stone as a mined diamond, the same carat, colour, clarity and cut is listed in our natural princess cut diamonds, and the difference between the two is the clearest way to decide which you actually want. Both are real diamonds; the lab grown stone simply lets the same budget go further on size.
Other shapes and the full range
If you are still deciding on outline, compare this against lab grown radiant cut diamonds, lab grown cushion cut diamonds, lab grown asscher cut diamonds. The whole lab grown diamond inventory lists every shape side by side with the same filters.

Frequently asked questions
What should I look for in a princess cut diamond?
The four corners are the thinnest points on the stone and the most vulnerable to chipping, so a setting with claws that cover them is worth insisting on. Princess also loses far less rough in cutting than a round, which is why it is consistently better value per carat.
Are lab grown princess cut diamonds real diamonds?
Yes. A lab grown diamond is the same carbon crystal as a mined one, with the same hardness and the same optical properties, and the two cannot be told apart by eye. Every stone here carries an independent grading report that names it as laboratory grown and a laser inscription on the girdle matching that report.
Can I have a princess cut diamond set into a ring?
Yes. Every lab grown princess cut diamond here is sold loose, so you choose the stone first and the setting second. Diamond Story sets loose stones into engagement rings, pendants and earrings in our Melbourne workshop, and we will advise on the setting that suits the shape you have chosen.
