Lab Grown Cushion Cut Diamonds
A cushion is a square or slightly rectangular stone with rounded corners and larger facets, a shape that has been cut for well over a century. It gives a softer, warmer, more antique look than the sharp geometry of a princess.
Use the filters above to narrow this lab grown cushion 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 cushion cut diamond
Cushions come in two faceting styles. Chunky cushions show broad flashes of light; crushed ice cushions scatter it into many small sparkles. Neither is graded as better, they simply look different, so decide which you prefer before you filter. The rounded corners also make it more durable than a princess.
Lab grown or natural cushion cut?
Every stone on this page is lab grown. If you want to price the same cushion cut stone as a mined diamond, the same carat, colour, clarity and cut is listed in our natural cushion 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 princess cut diamonds, lab grown radiant cut diamonds, lab grown oval diamonds. The whole lab grown diamond inventory lists every shape side by side with the same filters. To see natural and lab grown stones together along with the current specials, go to our loose diamonds at wholesale.
Frequently asked questions
What should I look for in a cushion cut diamond?
Cushions come in two faceting styles. Chunky cushions show broad flashes of light; crushed ice cushions scatter it into many small sparkles. Neither is graded as better, they simply look different, so decide which you prefer before you filter. The rounded corners also make it more durable than a princess.
Are lab grown cushion 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 cushion cut diamond set into a ring?
Yes. Every lab grown cushion 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.
