Lab Grown Radiant Diamonds
A radiant is the bridge between the two families. It takes the square or rectangular outline of an emerald cut, crops the corners, and fills it with brilliant faceting instead of step facets. The result is one of the liveliest stones in the range.
Use the filters above to narrow this lab grown radiant 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 radiant cut diamond
Because the faceting is busy, a radiant hides inclusions and colour better than almost any other shape, so it is the shape where you can drop a grade or two on clarity and colour and keep the saving. The cropped corners also make it durable. Check the length to width ratio to be sure you are getting the square or the rectangle you intended.
Lab grown or natural radiant cut?
Every stone on this page is lab grown. If you want to price the same radiant cut stone as a mined diamond, the same carat, colour, clarity and cut is listed in our natural radiant 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 cushion cut diamonds, lab grown emerald 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 radiant cut diamond?
Because the faceting is busy, a radiant hides inclusions and colour better than almost any other shape, so it is the shape where you can drop a grade or two on clarity and colour and keep the saving. The cropped corners also make it durable. Check the length to width ratio to be sure you are getting the square or the rectangle you intended.
Are lab grown radiant 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 radiant cut diamond set into a ring?
Yes. Every lab grown radiant 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.
